Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. Wiring Main Circuit Inputs Observe the following precautions for the main circuit power supply input. 2 2-14 Installing Fuses To protect the inverter, it is recommended to use semiconductor fuses like they are shown in the table below. Table 2.
Installing a Moulded-case Circuit Breaker When connecting the power input terminals (R/L1, S/L2, and T/L3) to the power supply using a moulded-case circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter. • Choose an MCCB with a capacity of 1.5 to 2 times of the inverter's rated current. • For the MCCB's time characteristics, be sure to consider the inverter's overload protection (one minute at 150% of the rated output current).
Wiring the Output Side of Main Circuit Observe the following precautions when wiring the main output circuits. Connecting the Inverter and Motor Connect output terminals U/T1, V/T2, and W/T3 respective to the motor lead wires U, V, and W. Check that the motor rotates forward with the forward run command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run command.
Ground Wiring Observe the following precautions when wiring the ground line. • Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that of the 400 V Inverter with a ground resistance of less than 10 Ω. • Do not share the ground wire with other devices, such as welding machines or power tools. • Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire.
Connecting a Braking Resistor Unit (LKEB) and Braking Unit (CDBR) Connect a Braking Resistor Unit and Braking Unit to the Inverter as shown in the Fig 2.8. The internal braking resistor overheat protection must be disabled (See table below). 2 L8-01 (Protection selection for internal DB resistor) 0 (Disable overheat protection) L3-04 (Stall prevention selection during deceleration) (Select either of them.
Connecting Braking Units in Parallel When connecting two or more Braking Units in parallel, use the wiring and jumper settings like shown in Fig 2.9. There is a jumper for selecting whether each Braking Unit is to be a master or slave. Select “Master” for the first Braking Unit only, and select “Slave” for all other Braking Units (i.e. from the second Unit onwards).
Wiring Control Circuit Terminals Wire Sizes For remote operation using analog signals, keep the control line length between the Analog Operator or operation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control circuits to reduce induction from peripheral devices.
Wiring Method Use the following procedure to connect wires to the terminal block. 1. Loosen the terminal screws with a thin-slot screwdriver. 2. Insert the wires from underneath the terminal block. 3. Tighten the terminal screws firmly Screwdriver Blade of screwdriver Control circuit terminal block Strip the end for 7 mm if no solderless terminal is used. 2 Solderless terminal or wire without soldering Wires 3.5 mm max. Blade thickness: 0.6 mm max. Fig 2.

Trial Operation Procedure......................................................4-2 Trial Operation .......................................................................4-3 Adjustment Suggestions ......................................................
Trial Operation Procedure Perform trial operation according to the following flowchart. When setting the basic parameters, always set C6-01 (Heavy/Normal Duty Selection) according to the application. START Installation Wiring Set power supply voltage jumper.*1 Turn ON power. Confirm status. Select operating method. Basic settings (Quick programming mode) V/f control? 4 NO Vector Control (A1-02=2 or 3)*5 YES V/f Control with PG (A1-02=1) YES PG? NO V/f control Set E1-03.
Trial Operation Application Confirmation For applications with quadratic torque characteristic like pumps, fans or blowers set C6-01 (Heavy/Normal Duty selection) to 1 or 2 (Normal Duty 1 or 2). Select the Normal Duty mode (1 or 2) regarding the required overload capability. For applications with constant torque characteristics like conveyors etc. always set C6-01 to 0 (Heavy Duty). The default setting is of C6-01 is 0 (Heavy Duty).
Power ON Confirm all of the following items and then turn ON the power supply. • Check that the power supply is of the correct voltage. 200 V class: 3-phase 200 to 240 VDC, 50/60 Hz 400 V class: 3-phase 380 to 480 VDC, 50/60 Hz • Make sure that the motor output terminals (U, V, W) and the motor are connected correctly. • Make sure that the Inverter control circuit terminal and the control device are wired correctly. • Set all Inverter control circuit terminals to OFF.
Basic Settings Switch to the quick programming mode (“QUICK” will be displayed on the LCD screen) and set the following parameters. Refer to Chapter 3 Digital Operator and Modes for Digital Operator operating procedures and to Chapter 5 User Parameters and Chapter 6 Parameter Settings by Function for details on the parameters. Table 4.1 Basic Parameter Settings : Must be set.

ParameClass ter Number 4 Name Description Setting Range E1-01 Input voltage set- Sets the Inverter's nominal input voltage ting in volts. 155 to 255 V (200 V class) 310 to 510 V (400 V class) E2-01 Motor rated current 10% to 200% of Inverter's rated current H4-02 and H4-05 Can be used to adjust the analog output FM and AM terwhen an instrument is connected to the minal output gain FM or AM terminal.
Settings for the Control Methods The usable Autotuning methods depend on the control method setting of the Inverter. Overview of Settings Make the required settings in quick programming mode and autotuning mode according to Fig 4.1. Setting the Control Method Select the appropriate control mode as required by the application. Table 4.2 shows the main properties of each control mode. Table 4.
Open Loop Vector Control (A1-02 = 2) Always perform autotuning. If the motor can be operated, perform rotating autotuning. If the motor cannot be operated, perform non-rotating autotuning. Refer to the following section on Autotuning for details on autotuning. Closed Loop Vector Control (A1-02=3) Always perform autotuning. If the motor can be operated, perform rotating autotuning. If the motor cannot be operated, perform non-rotating autotuning.
Precautions Before Using Autotuning Read the following precautions before using autotuning. • Autotuning an Inverter is fundamentally different from autotuning a servo system. Inverter autotuning automatically adjusts parameters according to detected motor data, whereas servo system autotuning adjusts parameters according to the detected size of the load. • When speed precision or torque precision is required at high speeds (i.e.
Precautions for Rotating and Non-rotating Autotuning • If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown in Fig 4.3 to prevent saturation of the Inverter’s output voltage. Use the following procedure to perform autotuning. 1. Input the voltage of the input power supply to T1-03 (Motor rated voltage). 2.
Parameter Settings for Autotuning The following parameters must be set before autotuning. Table 4.3 Parameter Settings before Autotuning Parameter Number *1 T1-00 T1-01 Name Display Motor 1/2 selection Select Motor Autotuning mode selection Tuning Mode Sel T1-02 T1-03 Setting Range Factory Setting V/f V/f with PG Open Loop Vector Closed Loop Vector Set the location where the autotuned motor data are to be stored.
Application Settings Parameters can be set as required in advanced programming mode (i.e. “ADV” is displayed on the LCD screen). All the parameters which can be set in quick programming mode are also displayed and can be set in the advanced programming mode. Setting Examples • The following points are examples of settings for applications. • When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor overheating protection.
Operation using the Digital Operator • Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation. • If fault occurs during operation, make sure that the STOP key on the Digital Operator is accessible easily. • At first, set the frequency reference to a low speed, e.g. to one tenth of the normal operating speed.
Adjustment Suggestions If hunting, vibration, or other problems originated in the control system occur during trial operation, adjust the parameters listed in the following table according to the control method. This table lists the most commonly used parameters only.

Application and Overload Selections Select the Overload to Suit the Application Set C6-01 (Heavy Duty: constant torque, Normal Duty: High carrier, variable torque) depending on the application. The setting ranges for the Inverter carrier frequency, overload capability and maximum output frequency depend on the setting of C6-01. For applications like fans and blowers (quadratic torque characteristic) set C6-01 to 1 or 2 (Normal Duty 1 or 2).
Setting Precautions C6-01 (Heavy/Normal Duty Selection) The inverter supplies Heavy/Normal Duty modes Heavy Duty, Normal Duty 1 and Normal Duty 2. The setting ranges and factory settings of some parameters change with the setting of C6-01. See page 5-74, Parameter Initial Values that Change With the Setting of C6-01 and page 5-75, Parameter Setting Ranges that Change With the Setting of C6-01. The table below shows the main differences of the three modes.
• When using V/f control or V/f control with PG, the carrier frequency can be set to vary depending on the output frequency, as shown in the following diagram by setting C6-03 (Carrier Frequency Upper Limit), C6-04 (Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain). Carrier Frequency C6-03 Output frequency x C6-05 x K* C6-04 Output frequency E1-04 Max. Output Frequency *K is the coefficient determined by the set value in C6-03. C6-03 ≥ 10.0 kHz: K=3 10.0 kHz > C6-03 ≥ 5.
Carrier Frequency and Inverter Overload Capability The inverter overload capability depends among other things on the carrier frequency setting. If the carrier frequency setting is higher than the factory setting, the overload current capability must be reduced. Heavy Duty (C6-01=0) The default carrier frequency for the Heavy Duty mode is 2 kHz. The overload capability is 150% of the Heavy Duty rated current for 1 minute.
Normal Duty 1 (C6-01=1) The default carrier frequency for the Normal Duty 1 mode depends on the inverter capacity. The overload capability is 120% of the Normal Duty 1 rated current for 1 minute. If the carrier frequency is set to a higher value than the factory setting, the overload capability is reduced like shown in Fig 6.3. 200V Class 37 to 90kW 400V Class 75 to 110kW 200V Class 0.4 to 22kW 400V Class 0.4 to 22kW 120% 96% 90% Output Current for 1 min.
Frequency Reference Selecting the Frequency Reference Source Set parameter b1-01 to select the frequency reference source. Related Parameters Parameter No.
2-Step Switching: Master/Auxiliary If performing 2-step switching between master and auxiliary speed frequencies, input the master speed frequency reference to control circuit terminal A1, and input the auxiliary speed frequency reference to A2.
Setting Frequency Reference Using Pulse Train Signals When b1-01 is set to 4, the pulse train input signal at terminal RP input is used as the frequency reference. Set H6-01 (Pulse Train Input Function Selection) to 0 (frequency reference), and then set the reference pulse frequency that is equal to 100% of the reference value to H6-02 (Pulse Train Input Scaling). Inverter Pulse Input Specifications Low level voltage 0.0 to 0.8 V High level voltage 3.5 to 13.
Using Multi-Step Speed Operation The inverter supports a multi step speed operation with a maximum of 17 speed steps, using 16 multi-step frequency references, and one jog frequency reference. The following example of a multi-function input terminal function shows a 9-step operation using multi-step references 1 to 3 and jog frequency selection functions. Related Parameters To switch frequency references, set multi-step references 1 to 3 and the jog reference selection in the multifunction digital inputs.
Setting Precautions When setting analog inputs to step 1 and step 2, observe the following precautions. • When setting terminal A1's analog input to step 1 set b1-01 to 1, when setting d1-01 (Frequency Reference 1) to step 1 set b1-01 to 0. • When setting terminal A2's analog input to step 2 set H3-09 to 2 (auxiliary frequency reference). When setting d1-02 (Frequency Reference 2) to step 2 set H3-09 to an other setting than 2.
Run Command Input Methods Selecting the Run Command Source Set parameter b1-02 to select the source for the run command. Related Parameters Parameter No. Name Factory Setting Change during Operation b1-02 RUN command source selection 1 No V/f Q Control Methods Open Closed V/f with Loop Loop PG Vector Vector Q Q Q Performing Operations Using the Digital Operator When b1-02 is set to 0, you can perform Inverter operations using the Digital Operator keys (RUN, STOP, and FWD/REV).
Performing Operations Using 3-Wire Control If one of the parameter H1-01 to H1-05 (digital input terminals S3 to S7) is set to 0, the terminals S1 and S2 are used for a 3-wire control, and the multi-function input terminal that has been set to 0 works as a forward/ reverse selection command terminal. When the Inverter is initialized for 3-wire control with A1-03, multi-function input 3 becomes the input terminal for the forward/reverse run command.
Stopping Methods Selecting the Stopping Method when a Stop Command is Input There are four methods of stopping the Inverter when a stop command is input: • Deceleration to stop • Coast to stop • DC braking stop • Coast to stop with timer Set parameter b1-03 to select the Inverter stopping method. DC injection braking to stop (b1-03=2) and coast to stop with a timer (b1-03=3) can not be set for Closed Loop Vector control. Related Parameters Parameter No.
When Closed Loop Vector control is selected, the stopping behavior depends on the setting of b1-05. RUN OFF ON fref Analog frequency reference E1-09 0 The Run command turns OFF and zero speed control starts when the motor speed feedback drops below b2-01.
DC Braking to Stop (b1-03=2) After the stop command has been input and the minimum baseblock time (L2-03) has elapsed, DC injection will be applied to the motor. The applied DC injection current can be set in parameter b2-02. The DC injection braking time depends on the set value of b2-04 and on the output frequency at the moment when the stop command is input and.
Using the DC Injection Brake The DC injection brake can be used to stop a coasting motor before restarting it or to hold it at the deceleration end when the inertia is large. Set parameter b2-03 to apply DC injection to the motor, before it starts to accelerate. Set parameter b2-04 to apply a DC injection brake to the motor at stopping. Setting b2-03/04 to 0 to disables the DC injection brake at start/stop. Set the DC injection brake current using b2-02.
Changing the DC Injection Brake Current Using an Analog Input If you set H3-09 (Analog Input Terminal A2 Function Selection) to 6 (DC injection brake current), you can change the DC injection brake current level using the analog input. At 10 V input (voltage) or 20 mA input (current), 100% of the Inverter rated current will be applied. DC injection brake current level Inverter rated current Fig 6.
Acceleration and Deceleration Characteristics Setting Acceleration and Deceleration Times The acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum output frequency (E1-04). The deceleration time indicates the time to decrease the output frequency from 100% to 0% of (E1-04). The accel./decel. times 1 are used with the factory setting, the accel./decel. times 2 to 4 can be selected using a multifunction digital input. Related Parameters Parameter No.
Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal Commands Four different acceleration times and deceleration times can be set. When the multi-function input terminals (H1) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/deceleration time selection 2), you can switch the acceleration/deceleration time even during operation by combining the ON/ OFF status of the terminals.
Adjusting Acceleration and Deceleration Time Using an Analog Input If you set H3-09 (Analog Input Terminal A2 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the acceleration/deceleration time using terminal A2's input voltage. The resulting acceleration time is as follows: Acceleration time = C1-01 set value x acceleration/deceleration time gain Acceleration/deceleration time gain (Acceleration/deceleration gain from 1 to 10 V) = 10 V/Input voltage (V) x 10 (%) Fig 6.
Accelerating and Decelerating Heavy Loads (Dwell Function) The dwell function holds the output frequency temporarily when starting or stopping heavy loads. When using the dwell function, deceleration to stop must be set as stopping method (b1-03 = 0). Related Parameters Parameter No.

Preventing Overvoltage During Deceleration The stall prevention during deceleration function lengthens the deceleration time automatically with respect to the DC-bus voltage to avoid overvoltage tripping. Related Parameters Parameter No.
Setting Example An example of stall prevention during deceleration when L3-04 is set to 1 is shown below. Output frequency Deceleration time controlled to prevent overvoltage Time Deceleration time (set value) Fig 6.28 Stall Prevention During Deceleration Operation Setting Precautions • The stall prevention level during deceleration differs depending on the inverter rated voltage and input voltage. Refer to the following table for details.

Adjusting Frequency Gain Using an Analog Input When H3-09 is set to 1 (frequency gain), the frequency gain can be adjusted using analog input A2. Frequency gain Multi-function analog input terminal A2 input level Fig 6.30 Frequency Gain Adjustment (Terminal A2 Input) The frequency gain for terminal A1 is the product of H3-02 and gain which is input at terminal A2. For example, when H3-02 is set to 100% and the terminal A2 input is 5 V, the frequency reference gain will be 50%.
Operation Avoiding Resonance (Jump Frequency Function) The jump frequency function allows the prohibition or “jumping” of certain frequencies within the Inverter’s output frequency range so that the machine can operate without oscillations caused by resonant frequencies of the machine. It can also be used for deadband control. During acceleration and deceleration the output frequency goes linear through the prohibited frequency ranges, i.e.
Setting Jump Frequency Reference Using an Analog Input When parameter H3-09 (analog input A2 function selection) is set to A (jump frequency), the jump frequency can be changed by the terminal A2 input value. Jump frequency Max. output frequency E1-04 Multi-function analog input terminal A2 input level Fig 6.35 Jump Frequency Setting Using an Analog Input Setting Precautions • Set the jump frequencies according to the following formula: d3-01 ≥ d3-02 ≥ d3-03 > Analog input.
Speed Limit (Frequency Reference Limits) Limiting the Maximum Output Frequency If the motor is not allowed to rotate above a certain frequency, use parameter d2-01 to set a frequency reference upper limit. The limit value is set as a percentage, taking E1-04 (Maximum Output Frequency) to be 100%. Related Parameters Parameter No. d2-01 Name Frequency reference upper limit Factory Setting Change during Operation 100.

Related Parameters Parameter No. Name Factory Setting Change during Operation V/f Control Methods Open Closed Loop Loop Vector Vector V/f with PG L4-01 Speed agreement detection level 0.
Time Charts The following table shows the time charts for each of the speed agreement functions.
Improving the Operation Performance Reducing the Motor Speed Fluctuation (Slip Compensation Function) When the load is large, the motor slip also grows and the motor speed decreases. The slip compensation function keeps the motor speed constant, regardless of changes in load. When the motor is operating at the rated load, parameter E2-02 (Motor Rated Slip) × the slip compensation gain value in parameter C3-01 is added to the output frequency. Related Parameters Parameter No.
Adjusting Slip Compensation Primary Delay Time Constant (C3-02) The slip compensation delay time constant is set in ms. The setting value of C3-02 depends on the control method. The factory settings are: • V/f control without PG: 2000 ms • Open loop vector control: 200 ms Normally, there is no need to change these settings. When the slip compensation response is low, lower the set value. When the speed is unstable, increase the set value.
Torque Compensation for Sufficient Torque at Start and Low-speed Operation The torque compensation function detects a rising motor load, and increases the output torque. In V/f control the inverter calculates the motor primary loss voltage using the terminal resistance value (E205) and adjusts the output voltage (V) to compensate insufficient torque at startup and during low-speed operation. The compensation voltage is calculated by the calculated Motor primary voltage loss × parameter C4-01.
Adjusting the Torque Compensation Primary Delay Time Constant (C4-02) The setting value of C4-02 depends on the control method. The factory settings are: • V/f control without PG: 200 ms • V/f control with PG: 200 ms • Open loop vector control: 20 ms Normally, there is no need to change this setting. If adjustments are necessary do the following: • If the motor is vibrating, increase the set value. • If the torque response is slow, decrease the set value.
In V/f control with PG the ASR adjusts the output frequency in order to eliminate the deviation between the speed reference and the measured speed (PG feedback). Fig 6.41 shows the ASR structure for V/f control with PG. Frequency Reference + Output Frequency C5-01/03 + Motor Speed + P - + + C5-05 ASR Limit I C5-02/04 Fig 6.41 ASR Structure for V/f control with PG Related Parameters Parameter No.
ASR Gain and Integral Time Adjustments for Closed Loop Vector Control General Procedure 1. Operate the motor at zero speed. 2. Increase C5-01 (ASR proportional gain 1) to a level where no oscillation in the motor speed occurs. 3. Decrease C5-04 (ASR integral time 2) to a level where no oscillation in the motor speed occurs. 4. Increase the speed and observe the motor speed. If oscillations occur at any speed the gain must be decreased and/or the integral time must be increased. 5.
Different Gain Settings for Low-speed and High-speed Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the mechanical system at low speed or high speed. The gain and integral time can be switched according to the motor speed, as shown in Fig 6.43. P=C5-01 I=C5-02 P,I P=C5-03 I=C5-04 0 Motor Speed C5-07 Fig 6.43 Low-speed and High-speed Gain Settings If C5-07 is set to 0, the gain in C5-01 and the integral time in C5-02 are used for the whole speed range.
ASR Gain and Integral Time Adjustments for V/f control with PG When using V/f control with PG, set the ASR gain and the integral time at E1-09 (minimum output frequency) and E1-04 (maximum output frequency). See Fig 6.45 for details. P,I P=C5-01 I=C5-02 P=C5-03 I=C5-04 0 E1-09 Min. Output Frequency E1-04 Max. Output Frequency Motor Speed Fig 6.
Hunting-Prevention Function The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function can be used in the V/f control modes only. If high response has the priority to vibration suppression this function should be disabled (N1-01 = 0). Related Parameters Parameter No. Name N1-01 Hunting-prevention function selection N1-02 Hunting-prevention gain Factory Setting Change during Operation 1 1.
Stabilizing Speed (Automatic Frequency Regulator) The speed feedback detection control (AFR) function controls the stability of the speed when a load is suddenly applied or removed. It calculates the amount of speed fluctuation using the torque current (Iq) feedback value and compensates the output frequency with the amount of fluctuation. fout fref Iq Fig 6.46 AFR Control Loop Related Parameters Parameter No.
Machine Protection Limiting Motor Torque (Torque Limit Function) This function allows limitation of motor shaft torque independently for each of the four quadrants. The torque limit can be set as fixed value using parameters or as variable value using an analog input. The torque limit function can be used with Open Loop Vector and Closed Loop Vector control only. Related Parameters Parameter No.
Set the Torque Limit Value Using an Analog Input The analog input A2 can be used to input several torque limits. The table below shows the possible analog input settings (H3-09) for the torque limit function.
Setting Precautions • When the output torque reaches the torque limit, control and compensation of the motor speed is disabled to prevent the output torque from exceeding the torque limit. The torque limit has the priority. • When using the torque limit for hoist applications, do not carelessly lower the torque limit value, as this may result in motor stalling.
Motor Torque Detection If an excessive load is applied to the machinery (overtorque) or the load drops suddenly (undertorque), an alarm signal can be output to one of the digital output terminals M1-M2, M3-M4, or M5-M6. To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/NC) in one of the parameter H2-01 to H2-03 (digital output terminals M1-M2, M3-M4, and M5-M6 function selection).
L6-01 and L6-04 Set Values and Operator Display The relationship between alarms displayed on the digital operator when overtorque or undertorque is detected, and the set values in L6-01 and L6-04, is shown in the following table. Set Value Operator Display Overtorque/ Overtorque/ Undertorque Undertorque Detection 1 Detection 2 Function 0 Overtorque/undertorque detection disabled. 1 Overtorque detection only with speed agree; operation continues (warning is output).
Changing Overtorque and Undertorque Detection Levels Using an Analog Input If parameter H3-09 (Analog Input A2 Function Selection) is set to 7 (overtorque/undertorque detection level), the overtorque/undertorque detection level can be changed using the analog input A2 (refer to Fig 6.53). Only the overtorque/undertorque detection level 1 can be changed using the analog input. Overtorque/undertorque detection level 2 cannot be changed by an analog input signal.
Setting Motor Overload Protection Characteristics (L1-01) Set the overload protection function in L1-01 according to the used motor. The induction motor's cooling abilities vary with the motor type. Consequently, you must select the electronic thermal protection characteristics. Set L1-01 to: 0: to disable the thermal motor protection function. 1: to enable the thermal motor protection for a fan cooled general purpose motor (self-cooled).
Motor Overheating Protection Using PTC Thermistor Inputs This function provides a motor overheating protection using a thermistor (PTC characteristic – Positive Temperature Coefficient) which is built into the windings of each motor phase. The thermistor must be connected to an analog input. Related Parameters Parameter No.
Terminal Connection The terminal connection for the motor overheat function is shown in Fig 6.56. The following points have to be considered: • Pin 2 of the DIP-switch S1 on the control terminal board has to be turned to OFF for A2 voltage input. The factory setting is ON (A2 current input). • Parameter H3-09 has to be set to “E” • Parameter H3-08 (analog input terminal A2 signal level) has to be set to 0 (0-10V input).
Automatic Restart This section explains functions for continuing or automatically restarting inverter operation after a momentary power loss. Restarting Automatically After Momentary Power Loss If a temporary power loss occurs, the inverter can be restarted automatically to continue motor operation. To restart the Inverter after the power has returned, set L2-01 to 1 or 2. If L2-01 is set to 1, the inverter will restart as long as the power is recovered within the time set in L2-02.
Speed Search The speed search function detect the actual speed of a motor that is coasting without control and restart it smoothly from that speed. It is also activated after momentary power loss detection when L2-01 is set to enabled. Related Parameters Parameter No.
Setting Precautions • When both external search commands 1 and 2 are set for the multi-function contact terminals, an OPE03 (invalid multi-function input selection) operation error will occur. Set either external search command 1 or external search command 2. • If speed search during startup is selected when using V/f control with PG or Closed Loop Vector control the unit will start from the frequency detected by PG.
Speed Calculation Search at Startup The time chart for when speed search at startup and speed search to multi-function input terminals is shown below.

Continuing Operation at Constant Speed when the Frequency Reference is Lost The frequency reference loss detection function detects a loss of the frequency reference value. If an analog frequency reference source is selected, a frequency reference loss is detected, when the reference value drops over 90% in 400 ms or less. The operation after a reference loss can be set in parameter L5-01 as follows: • L5-01=0 The inverter operation is stopped.
Restarting Operation After Transient Error (Auto Restart Function) If an Inverter error occurs during operation, the Inverter will perform self-diagnosis. If no error is detected, the Inverter will automatically restart. This is called the auto restart function. Set the number of auto restarts in parameter L5-01. The auto restart function can be applied to the following errors.
Inverter Protection Overheating Protection for an Inverter-Mounted Braking Resistor This function provides overheat protection for inverter-mounted braking resistors (Model: ERF-150WJ ). When overheating of a mounted braking resistor is detected, an fault RH (mounted braking resistor overheating) is displayed on the Digital Operator, and the motor coasts to stop. The fault can be output using one of the multi-function contact outputs as well.
Inverter Overheat Protection The Inverter is protected against overheating using a thermistor that detects the heatsink temperature. When the overheat temperature level is reached the inverter output is switched off. To prevent a suddenly and unexpected stop of the inverter due to an over temperature, an overheating prealarm can be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using parameter L8-03 the inverter operation when an over temperature occurs can be selected.
Output Open Phase Protection This function detects an open output phase by comparing the output current value of each phase with an internal set output open phase detection level (5% of inverter rated current). The detection will not work when the output frequency is below 2% of the base frequency (E1-13).
Selecting the Cooling Fan Control Using parameter L8-10 two modes can be selected: 0:The fan is ON only when the inverter output is ON, i.e. a voltage is output. This is the factory setting. 1:The fan is ON whenever the inverter power supply is switched ON. If L8-10 is set to 0, the turn OFF delay time for the fan can be set in parameter L8-11. After a stop command the inverter waits for this time before switching OFF the cooling fan. The factory setting is 60 sec.
OL2 Characteristics at Low Speed At output frequencies below 6 Hz the overload capability of the inverter is lower than at higher speeds, i.e. an OL2 fault (inverter overload) may occur even if the current is below the normal OL2 current level (see Fig. 6.61). OL2 Detection Level* 150% (120%)* for 1 min. 75% (60%)* for 1 min. -6 Hz 0 Hz Output Speed 6 Hz * Note that the OL2 level depends on the setting of C6-01. The values are given for Heavy Duty.
Input Terminal Functions Temporarily Switching Operation between Digital Operator and Control Circuit Terminals The Inverter run command inputs and frequency reference inputs can be switched over between Local and Remote. • Local:The digital operator is used as frequency reference and run command source. • Remote:The frequency reference and run command source can be set in the parameters b1-01 and b1-02.

Application Precautions • Frequency references which use the UP/DOWN commands are limited by the frequency reference upper and lower limits set in parameters d2-01 to d2-03. In this case the value from the input A1 becomes the frequency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either parameter d2-02 or d2-03, the larger limit value will become the frequency reference lower limit.

Hold Analog Frequency Using User-set Timing When one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selection) is set to 1E (sample/hold analog frequency command), the analog frequency reference will be held from 100 ms after the terminal is turned ON, and operation will continue at that frequency. The analog value 100 ms after the command is turned ON is used as the frequency reference. Sample/hold command Analog input Frequency reference Fig 6.
Switching Operation Source to Communication Option Card The source of frequency reference and RUN command can be switched between a Communication option card and the sources selected in b1-01 and b1-02. Set one of the parameters H1-01 to H1-05 (digital inputs S3 to S7 function selection) to 2 to enable operation source switch over. If a RUN command is active, the switch over will not be accepted.
Stopping the Inverter on External Device Errors (External Error Function) The external error function activates the error contact output and stops the Inverter operation. Using this function the inverter operation can be stopped on peripheral devices break down or other errors. The digital operator will display EFx (External error [input terminal Sx]). The x in EFx shows the number of the terminal at which the external error signal is input.
Output Terminal Functions The digital multifunction outputs can be set for several functions using the H2-01 to H2-03 parameters (terminal M1 to M6 function selection). These functions are described in the following section. Related Parameters Parameter No.
Inverter Operation Ready (Setting: 6) If a multifunction output is programmed for this function the output will be switched ON when the initialisation of the inverter at startup has finished without any faults. During DC Bus Undervoltage (Setting: 7) If a multifunction output is programmed for this function the output is switched ON as long as a DC bus undervoltage is detected.
Motor 2 Selection (Setting: 1C) If a multifunction output is programmed for this function the output is switched ON when motor 2 is selected. During Regenerative Operation (Setting: 1D) If a multifunction output is programmed for this function the output is switched ON when the motor works regenerative, i.e. when energy is fed back to the inverter. During Run 2 (Setting: 37) When a multifunction output is set to this function the output is switched ON when a frequency is output.

Individual Functions Using MEMOBUS Communications Serial communications with a Programmable Logic Controls (PLCs) or similar devices can be performed using the MEMOBUS protocol. MEMOBUS Communications Configuration MEMOBUS communications are configured using 1 master (PLC) and a maximum of 31 slaves. Serial communications between master and slave are normally started by the master and the slaves respond. The master performs serial communications with only one slave at a time.
Communications Connection Terminal The MEMOBUS communications use the following terminals: S+, S-, R+, and R-.

Function Code The function code specifies commands. The three function codes shown in the table below are available. Command Message Function Code (Hexadecimal) Function Response Message Min. (Bytes) Max. (Bytes) Min. (Bytes) Max.
The following example clarifies the calculation method. It shows the calculation of a CRC-16 code with the slave address 02H (0000 0010) and the function code 03H (0000 0011). The resulting CRC-16 code is D1H for the lower and 40H for the higher byte. The example calculation in this example is not done completely (normally data would follow the function code).
MEMOBUS Message Example An example of MEMOBUS command/response messages is given below. Reading Inverter Memory Register Contents The content of maximum 16 inverter memory registers can be readout at a time. Among other things the command message must contain the start address of the first register that is to be read out and the quantity of registers that should be read out. The response message will contain the content of the first and the consecutive number of registers that has been set for the quantity.
Writing to Multiple Inverter Memory Registers The writing of inverter memory registers works similar to the reading process, i.e. the address of the first register that is to be written and the quantity of to be written registers must be set in the command message. The to be written data must be consecutive, starting from the specified address in the command message. The data order must be higher 8 bits, then lower 8 bits. The data must be in memory register address order.
Data Tables The data tables are shown below. The types of data are as follows: Reference data, monitor data, and broadcast data. Reference Data The reference data table is shown below. These data can be read and written. They cannot be used for monitoring functions.
Monitor Data The following table shows the monitor data. Monitor data can only be read. Register Address.
Register Address.

Register Address.
Broadcast Data Using broadcast data a command can be given to all slaves at the same time. The slave address in the command message must be set to 00H. All slaves will receive the message. They will not respond. The following table shows the broadcast data. You can also write this data.
ENTER Command When writing parameters to the Inverter from the PLC using MEMOBUS communications, the parameters are temporarily stored in the parameter data area of the Inverter. To enable these parameters in the parameter data area the ENTER command must be used.
Slave Not Responding In the following cases, the slave will ignore the write function. • When a communications error (overrun, framing, parity, or CRC-16) is detected in the command message. • When the slave address in the command message and the slave address in the Inverter do not agree. • When the gap between two blocks (8 bit) of a message exceeds 24 bits. • When the command message data length is invalid.
Using the Timer Function The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and multifunction output terminals M1-M2, M3-M4, and M5-M6 can be used as timer function output terminals. By setting the delay time, you can prevent chattering of the sensors and switches. • Set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7) to 18 (timer function input).
Using PID Control PID control is a method of making the feedback value (detection value) matching the set target value. By combining proportional control (P), integral control (I), and differential control (D), you can even control system with load fluctuation. The characteristics of the PID control operations are given below. P element The output of a P-element is proportional to the input (deviation). With using a P-element alone it is not possible to eliminate the deviation completely.

PID Input Methods PID Target Value Input Sources Normally, the frequency reference source selected in b1-01 is the PID target value source. Alternatively the PID target value can be set as shown in the following table. PID Target Input Method Setting Conditions Multi-Function Analog Terminal A2 Input Set H3-09 to C (PID target value). Either the pulse train input or the analog input A1 can be selected as PID feedback value.
PID Adjustment Examples Suppressing Overshoot If overshoot occurs, reduce Proportional gain (P), and increase integral time (I). Response Before adjustment After adjustment Time Set a Rapidly Stabilizing Control Condition To rapidly stabilize the control even if overshoot occurs, reduce integral time (I), and lengthen differential time (D).
Setting Precautions • In PID control, the b5-04 parameter is used to prevent the calculated integral control value from exceeding a specified amount. When the load varies rapidly, the Inverter response is delayed, and the machine might get be damaged or the motor may stall. In this case, reduce the set value to speed up Inverter response. • The b5-06 parameter is used to prevent the output value of the PID control calculation from exceeding a specified amount.

PID Feedback Loss Detection When performing PID control, be sure to use the PID feedback loss detection function. Otherwise if the PID feedback gets lost, the Inverter output frequency may accelerate to the maximum output frequency.
PID Sleep The PID sleep function stops the Inverter when the PID output value falls below the sleep operation level (b515) for the sleep operation time set in parameter b5-16. The inverter operation will resume, if the PID output value exceeds the sleep operation level for the time set in parameter b5-16 or longer. The PID sleep function works as well when the PID control is disabled. In this case the frequency reference value is observed by the sleep function instead of the PID output value.
Multifunction Digital Input Settings: H1-01 to H1-05 (Terminal S3 to S7) PID Control Disable: “19” • If a multifunction input is set for this function it can be used to disable the PID function by switching the input to ON. • The PID target value becomes the frequency reference value. PID Control Integral Reset: “30” • Using this function the integral share value of the PID control can be reset by setting a multifunction input to ON.
Energy-saving To use the energy saving function, set b8-01 (Energy Saving Mode Selection) to 1. Energy-saving control can be performed in all control methods. The parameters to be adjusted are different for each. In the V/f control modes adjust b8-04 to b8-05. In Open Loop and Closed Loop Vector control adjust b8-02 and b8-03. Related Parameters Parameter No.
Open Loop and Closed Loop Vector Control In Open Loop and Closed Loop Vector control, the slip frequency is controlled so that motor efficiency is maximized. • Taking the motor rated slip for the base frequency as optimum slip, the inverter calculates the slip for the optimal motor efficiency depending on the output frequency. • Before using energy saving always perform autotuning.
Field Forcing The field forcing function controls the motor flux and compensates the flux establishment delay of the motor. Thereby it improves the motor responsiveness on changes in the speed reference or the load. Field forcing is applied during all operation conditions except DC Injection. Using parameter d6-04 a field forcing limit can be applied. A setting of 100% is equal to the no-load current set in parameter E2-03. Related Parameters Parameter No.

Setting V/f Pattern (E1-02) The V/f pattern can be selected using parameter E1-03. There are two methods of setting the V/f pattern: Select one of the 15 preset pattern types (set value: 0 to E), or set a user-defined V/f pattern (set value: F). The factory setting for E1-03 is F. To select one of the existing patterns, refer to the following table.

Setting an Individual V/f Pattern If E1-03 is set to F the V/f pattern can be set individually using the parameters E1-04 to E1-10. See Fig 6.84 for details. Output voltage (V) Frequency (Hz) Fig 6.84 Individual V/f pattern setting INFO • If E1-03 is set to anything other than F, you can only read parameters E1-04 to E1-10. • To set the V/f characteristics linear, set E1-07 and E1-09 to the same value. In this case, E1-08 will be ignored.
Setting Motor 2 Parameters The E4parameters are for setting the motor data for motor 2. In the Vector Control modes the motor data are set automatically by autotuning. If the autotuning does not complete normally, set them manually (refer to page 6-109, Manual Setting of the Motor Parameters). To switch over between motor 1 and 2 a digital input must be set for the motor switch over command (one of the parameters H1-01 to H1-05 must be set to 16). Motor 2 is selected when the input is switched ON.
Setting the V/f Pattern 2 Using the E3- parameters the V/f pattern for motor 2 can be set as needed. It is not recommended to change the settings when the motor is used in open loop vector mode.

Torque Control With Closed Loop Vector control the motor's output torque can be controlled by a torque reference from an analog input. Torque control can be enabled by setting parameter d5-01 to 1. Related Parameters Parameter No.
Torque Control Operation In torque control a torque value can be given as reference for the motor output. If the torque command and the load are not balanced, the motor accelerates or decelerates. The speed limit circuit prevents the motor speed from rising above certain value set by an analog input or parameter d5-04. The speed limit function mainly consists of two parts, the priority circuit and the speed limiter circuit.
The direction of the torque output from the motor will be determined by the sign of the analog signal input or a digital input command. It does not depend on the direction of the run command. The direction of torque will be as follows: • Positive analog reference: Torque reference for forward motor rotation (counterclockwise as viewed from the motor output axis). • Negative analog reference: Torque reference for reverse motor rotation (clockwise as viewed from the motor output axis).
Speed Limit Bias Setting The speed limit bias can be set to limit both the forward and reverse speed to the same value. This differs from the operation of the speed limit setting. To use the speed limit bias, set d5-04 to 0 and set the bias in d5-05 as a percentage of the maximum output frequency. To set 50% forward and reverse speed limits, set the speed limit setting to 0 (d5-03 = 2, d5-04 = 0, and d5-05 = 50). The range of torque control will be from -50% to 50% of the maximum output speed.
put by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant speed.
Setting the Speed/Torque Control Switching Timer (d5-06) The delay between a change in the speed/torque control switching function input (ON to OFF or OFF to ON) and the corresponding change in the control mode can be set in parameter d5-06. During the timer delay, the value of the 2 analog inputs will retain the values they had when the ON/OFF status of speed/torque control switching signal was changed. Use this delay to complete any changes required in external signals. Fig 6.
Droop Control Function Droop control is a function that allows to achieve a load sharing between two motors that drive a single load. The Droop Control function must be enabled at one inverter only. If by this inverter the torque rises, the speed is reduced and the other inverter takes over more load. Thereby the load is shared automatically to both motors. Related Constants Parameter No.
Zero-Servo Function The Zero-Servo function holds the motor when the motor is stopped in a so called Zero-Servo status. This means, that if the frequency reference falls below the Zero-Speed level (parameter b2-01) a position loop is activated and the motor is kept at the position, even if a load is applied. The zero-servo function must be enabled using a digital input, which is programmed for is set to Zero-Servo command (H1= 72).
Timing Chart An example timing chart for the Zero-Servo function showing the input and output signals is given in the figure below. Run command OFF ON ON Zero Servo Command OFF Frequency (speed) reference Excitation level b2-01 Motor speed Zero Servo End signal Zero-servo status Fig 6.89 Time Chart for the Zero-Servo Function Application Precautions • Be sure to leave the run command input activated.
Kinetic Energy Buffering The kinetic energy buffering function can be used to decelerate to stop after a sudden power loss using the kinetic energy of the rotating machine to maintain the DC bus voltage. Thereby an uncontrolled coasting of a machine can be prevented. The function can be activated using a multifunction input that i.e. can be operated by a DC bus undervoltage alarm output or by a voltage drop relay. A wiring example is shown in Fig. 6.80.
Adjusting the Kinetic Energy Buffering Deceleration Time (C1-09) The fast stop time set in parameter C1-09 is used to decelerate to stop when a Kinetic Energy Buffering command is input. To set up this parameter do the following: • Increase C1-09 until a UV1 fault is detected during deceleration. (If L2-01 is set to 2, no UV1 will be detected, but the motor will start to coast when the DC bus voltage drops too much.

Changing the Units for Frequency Parameters Related to V/f settings (o1-04) Using parameter o1-04 the unit for frequency parameters related to the V/f setting can be changed. If o1-04 is set to 0 it will be Hz. If o1-04 is set to 1 it will be rpm. Changing the Display Contrast (o1-05) Using o1-05 the contrast of the LCD display on the digital operator can be raised or lowered. Lowering the o105 value will decrease the contrast and vice versa.
Cumulative Operation Time (o2-07 and o2-08) The inverter has a function that counts the operation time of the inverter cumulatively. Using parameter o2-07 the cumulative operation time can be changed, e.g. after a replacement of the control board. If parameter o2-08 is set to 0 the inverter counts the time whenever the power supply is switched ON. If o2-08 is set to 1 the time when a RUN command is active is counted only. The factory setting is 0.

Displaying User-set Parameters Only The A2 parameters (user-set parameters) and A1-01 (parameter access level) can be used to establish a parameter set that contains only the most important parameters. Set the number of the parameter to which you want to refer in A2-01 to A2-32, and then set A1-01 to 1. Using the advanced programming mode you can read and modify A1-01 to A1-03 and the parameters set in A2-01 to A2-32 only. Related Parameters Parameter No.
Option Cards Using PG Feedback Option Cards To get a more precise speed control the inverter can be equipped with a PG option card to connect a pulse generator. Two different PG cards can be used, the PG-B2 and the PG-X2. Refer to page 2-28, Option Card Models and Specifications to see details. Related Parameters Parameter No.
Suit the PG Rotation Direction and Motor Rotation Direction (F1-05) Parameter F1-05 suits the PG rotation direction to the motor rotation direction. If the motor is rotating forwards, set whether it is A-phase leads or B-phase leads.
Setting PG Pulse Monitor Output Dividing Ratio (F1-06) This function is enabled only when using PG speed control card PG-B2. Set the dividing ratio for the PG pulse monitor output. The set value is expressed as n for the higher place digit, and m for the two lower place digits. The dividing ratio is calculated as follows: Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32 F1-06 = n m The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1.
Analog Reference Cards When using a AI-14B or A1-14U analog reference card, set parameter b1-01 (Reference selection) to 3 (Option Card). The AI-14B provides 3 bi-polar input channels with 14-bit (plus sign) A/D conversion. If b1-01 is set to 1 and F2-01 is set to 0, the channel 1 and 2 replace the analog inputs A1 and A2. A1 becomes the frequency reference input and the function of A2 can be selected using parameter H3-09.
Selecting Input Terminal Functions for the DI-16H2 Digital Reference Card The frequency reference from the DI-16H2 Card is determined by the setting of F3-01 and the 12/16-bit switch on the Option card. The possible settings are listed in the table below. Terminal 1 Bit 0 (20) Bit 0 (20) 3-digit BCD with Sign F3-01 = 0 to 5 S1: 12 bit 1 2 Bit 1 (21) Bit 1 (21) 2 Pin No.
Selecting the Input Terminal Function for a DI-08 Digital Reference Card The frequency reference from a DI-08 Card is determined by the setting of F3-01, as shown in the following table. Terminal Pin No.
Selecting the Digital Reference The setting range of the digital references is determined by the combination of the settings of o1-03 and F3-01. The information monitored in U1-01 (Frequency reference) will also change. DI-16H2 Reference Setting Ranges With the DI-16H2 option card setting ranges can be set like shown in table below.
7 Troubleshooting This chapter describes the fault displays and countermeasures for Inverter and motor problems. Protective and Diagnostic Functions......................................7-2 Troubleshooting ...................................................................
Protective and Diagnostic Functions This section describes the fault and alarm functions of the Inverter. These functions include fault detection, alarm detection, operator programming error detection and auto-tuning error detection. Fault Detection When the Inverter detects a fault, the fault contact output operates and the Inverter output is switched OFF causing the motor to coast to stop. (The stopping method can be selected for some faults.) A fault code is displayed on the Digital Operator.

Alarm Detection Alarms are Inverter protection function that do not operate the fault contact output. The system will automatically return to its original status when the cause of the alarm has been removed. During an alarm condition, the Digital Operator display flashes and an alarm output is generated at the multifunction outputs (H2-01 to H2-03) if programmed When an alarm occurs, take appropriate countermeasures according to the table below. Table 7.

Check application/machine status to eliminate fault.
Table 7.
Operator Programming Errors An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual parameter setting is inappropriate. The Inverter will not operate until the parameter is set correctly; however, no alarm or fault outputs will occur. If an OPE occurs, change the appropriate parameter by checking the cause shown in Table 7.3. When OPE error is displayed, press the ENTER key to display U1-34 (OPE Detected).

Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started. If that occurs, use this section as a reference and perform the appropriate countermeasures. If the contents of the fault are displayed, refer to page -2, Protective and Diagnostic Functions. If A Parameter Cannot Be Set Use the following information if a parameter cannot be set.
If the Motor Does Not Operate Properly The following causes are possible: Ensure the Digital Operator is securely connected to the Inverter. The motor does not operate when the RUN key on the Digital Operator is pressed. The following causes are possible: The LOCAL/REMOTE mode is not selected properly. The status of the SEQ and the REF LEDs have to be OFF for LOCAL mode.
The motor only rotates in one direction. "Reverse run disabled" may be selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run prohibited), the Inverter will not accept any reverse run commands. If the Direction of the Motor Rotation is Reversed If the motor rotates in the wrong direction, the motor output wiring may be incorrect.
If the Motor Operates at Higher Speed than the Frequency Reference PID control is enabled. If the PID control is enabled (b5-01 = 1 to 4), the Inverter output frequency will change to regulate the process variable to the desired set point. The PID can command a speed up to Maximum Output Frequency (E1-04) even though the reference is much lower. If There is Low Speed Control Accuracy Above Base Speed in Open Loop Vector Control Mode The Inverter’s maximum output voltage is determined by its input voltage.
If the Motor Overheats The following causes are possible: The load is too large. If the motor load is too large and the torque exceeds the motor’s rated torque, the motor may overheat. Reduce the loads by either reducing the load or increasing the acceleration/deceleration times. Also consider increasing the motor size. The ambient temperature is too high. The motor rating is determined by a particular ambient operating temperature range.
If There is Mechanical Oscillation Use the following information when there is mechanical vibration: The application is making unusual sounds. The following causes are possible: There may be resonance between the mechanical system's natural frequency and the carrier frequency. This is characterized by the motor running with no noise generation, but the machinery vibrates with a highpitched whine. To prevent this type of resonance, adjust the carrier frequency with parameters C6-02 to C6-05.
If auto-tuning has not been performed, proper performance may not be achieved for Closed Loop Vector Control. Perform auto-tuning or set the motor parameters through hand calculations. Alternatively, change the Control Mode Selection to V/f Control (A1-02 = 0 or 1). Oscillation and hunting occur with PID control. If there is oscillation or hunting during PID control, check the oscillation cycle and individually adjust P, I, and D parameters. (Refer to page -96, Using PID Control.

8 Maintenance and Inspection This chapter describes basic maintenance and inspection for the Inverter. Maintenance and Inspection ..................................................
Maintenance and Inspection Periodic Inspection Check the following items during periodic maintenance. • The motor should not vibrate or make unusual noises. • There should be no abnormal heat generation from the Inverter or motor. • The ambient temperature should be within the Inverter’s specifications. • The output current value shown in U1-30 should not be higher than the motor or the Inverter rated current for extended period of time. • The cooling fan in the Inverter should be operating normally.
Periodic Maintenance of Parts In order to keep the Inverter operating normally over a long period of time, and to prevent down time due to an unexpected failure, it is necessary to perform periodic inspections and replace parts according to their service life. The data indicated in the following table is to be used as a general guideline only. Periodic inspection standards vary depending on the Inverter’s installation environment conditions and usage.
Cooling Fan Replacement 200 V and 400 V Class Inverters of 18.5 kW or Less A cooling fan is attached to the bottom of the Inverter. If the Inverter is installed using the mounting holes on the back of the Inverter, the cooling fan can be replaced without removing the Inverter from the installation panel. If the Inverter is mounted with the heatsink external to the enclosure, the cooling fan can only be replaced by removing the Inverter from the enclosure. Removing the Cooling Fan 1.
200 V and 400 V Class Inverters of 22 kW or More The heatsink cooling fan is attached to the top of the heatsink inside the Inverter. The cooling fan(s) can be replaced without removing the Inverter from the installation panel. Removing the Cooling Fan 1. Always turn OFF the input power before removing and installing the heatsink cooling fan assembly. 2. Remove the terminal cover, Inverter cover, Digital Operator, and front cover from the Inverter. 3.
Removing and Mounting the Terminal Card The Terminal Card can be removed and mounted without disconnecting the control wiring. Removing the Terminal Card 1. Remove the terminal cover, Digital Operator and front cover. 2. Remove the wires connected to FE and/or NC on the terminal card. 3. Loosen the mounting screws on the left and right sides of the terminal card (“1“) until they are free. It is not necessary to remove these screws completely. They are captive and self-rising. 4.

10 Appendix This chapter provides precautions for the Inverter, motor, and peripheral devices and also provides lists of constants. Inverter Application Precautions ..........................................10-2 Motor Application Precautions .............................................10-5 User Constants ....................................................................
Inverter Application Precautions Selection Observe the following precautions when selecting an Inverter. Installing Reactors A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a compensating capacitor. Excessive peak current can destroy the rectifier section. To prevent this, install a DC or AC reactor to improve the power supply power factor.
Installation Observe the following precautions when installing an Inverter. Installation in Enclosures Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter on wood or other combustible materials.
Handling Observe the following precautions when wiring or performing maintenance for an Inverter. Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully. Magnetic Contactor Installation If a magnetic contactor is installed in the power supply line do not exceed one start per hour.
Motor Application Precautions Using the Inverter for an Existing Standard Motor Observe the following precautions when using an Inverter for an existing standard motor. Low Speed Ranges If a standard cooled motor is used at low speed the cooling effects are diminished. If the motor is used in constant torque applications in low speed area the motor may overheat. If full torque is required at low speed continuously an externally cooled motor must be used.
Synchronous Motor A synchronous motor is not suitable for Inverter control. Single-phase Motor Do not use an Inverter for a single-phase capacitor motor. Any capacitors directly connected to the inverter output may damage the Inverter. Power Transmission Mechanism (Speed Reducers, Belts and Chains) If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will be affected when the motor operates only in the low speed range.
