" 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. Installing a Molded-case Circuit Breaker Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded-case circuit breaker (MCCB) suitable for the Drive. • Choose an MCCB with a capacity of 1.5 to 2 times the Drive's rated current.
Wiring Main Circuit Terminals Installing a Magnetic Contactor If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used. When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Drive, however, the regenerative braking does not work and the Drive will coast to a stop. • The Drive can be started and stopped by opening and closing the magnetic contactor on the primary side.
• Incorrect Noise Filter Installation Power supply MCCB Drive MCCB Power supply Generalpurpose noise filter IM Other controllers MCCB Generalpurpose noise filter Drive IM MCCB Other controllers Do not use general-purpose noise filters. Generalpurpose noise filter can not effectively suppress noise generated from the Drive. Fig 2.7 Incorrect Power supply Noise Filter Installation !Wiring the Output Side of Main Circuit Observe the following precautions when wiring the main output circuits.
Wiring Main Circuit Terminals Do Not Use an Electromagnetic Switch Never connect an electromagnetic switch (MC) between the Drive and motor and turn it ON or OFF during operation. If the MC is turned ON while the Drive is operating, a large inrush current will be created and the overcurrent protection in the Drive will operate. When using an MC to switch to a commercial power supply, stop the Drive and motor before operating the MC. Use the speed search function if the MC is operated during operation.
Countermeasures Against Radio Interference Radio noise is generated from the Drive as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Drive in a totally enclosed steel box. The cable between the Drive and the motor should be as short as possible. Power supply Steel box Metal pipe MCCB Noise filter Drive Noise filter IM Fig 2.
Wiring Main Circuit Terminals !Connecting the Braking Resistor (ERF) A Braking Resistor that mounts to the Drive can be used with 200-240 V and 380-480 V Class Drives with outputs from 0.4 to 3.7 kW. Connect the braking resistor as shown in Fig 2.12. Table 2.7 L8-01 (Protect selection for internal DB resistor) 1 (Enables overheat protection) L3-04 (Stall prevention selection during deceleration) (Select either one of them.
Wiring Control Circuit Terminals " Wire Sizes and Closed-loop Connectors For remote operation using analog signals, keep the control line length between the Digital Operator or operation signals and the Drive to 50 m (164 ft) or less, and separate the lines from high-power lines (main circuits or relay sequence circuits) to reduce induction from peripheral devices.

Basic settings (Quick programming mode) Vector (A1-02 = 2, 3, or 4)*5 V/f control? YES V/f (Default: A1-02 = 0) V/f with PG (A1-02 = 1) PG? Set E1-03. V/f default: 200 V/60 Hz(400 V/60 Hz) Set E1-03, E2-04, and F1-01.
Trial Operation Procedures Trial Operation Procedures The procedure for the trial operate is described in order in this section. " Setting the Power Supply Voltage Jumper (380-480 V Class Drives of 55 kW or Higher) Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 380-480 V Class Drives of 55 kW or higher. Insert the jumper into the voltage connector nearest to the actual power supply voltage. The jumper is factory-set to 440 V when shipped.
" Checking the Display Status If the Digital Operator's display at the time the power is connected is normal, it will read as follows: -DRIVE-DRIVE- Display for normal operation Rdy Frequency RefRef Frequency U1- 01 01= 60.0 0Hz U1-01= 0 0 0.0 0Hz U1-02=60.00Hz U1-03=10.05A The frequency reference monitor is displayed in the data display section. When an fault has occurred, the details of the fault will be displayed instead of the above display. In that case, refer to Chapter 7 Troubleshooting.
Trial Operation Procedures " Basic Settings Switch to the quick programming mode (“QUICK” will be displayed on the LCD screen) and then set the following user 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 user parameters. Parameters that must be set are listed in Table 4.1 and those that are set according to the application are listed in Table 4.2. Table 4.
Table 4.2 Parameters that Are Set as Required Parameter Number b1-03 C6-02 Name Stopping method selection Description Select stopping method when stop command is sent. 0: Deceleration to stop 1: Coast to stop 2: DC braking stop 3: Coast to stop with timer Carrier frequency selection Setting Range Factory Setting 0 to 3 0 1 to F Depends on capacity, voltage, and control mode. 1 to 4 Depends on kVA setting. 0.00 to 400.00 Hz d1-01 to d1-04: 0.00Hz d1-17: 6.00Hz 0.0 to 1000.
Trial Operation Procedures " Settings for the Control Methods Autotuning methods depend on the control method set for the Drive. Make the settings required by the control method. !Overview of Settings Make the required settings in quick programming mode and autotuning mode according to the following flowchart. START NO Vector (A1-02 = 2, 3, or 4)*3 V/f control? YES V/f (A1-02 = 0 or 1) Control mode selection PG? YES (A1-02 = 1) NO (Default: A1-02 = 0) Set E1-03.
!Setting the Control Method Any of the following five control methods can be set.
Trial Operation Procedures • Set the number of rotations per pulse in F1-01 (PG Constant). If there is a reduction gear between the motor and PG, set the reduction ratio in F1-12 and F1-13 in advanced programming mode. • Perform stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for the actual installation or the load is heavy enough to produce stalling. Refer to the following section on Autotuning for details on stationary autotuning.
Stationary Autotuning for Line-to-Line Resistance Only (T1-01 = 2) Stationary autotuning for line-to-line resistance only can be used in any control method. This is the only autotuning possible for V/f control and V/f control with PG modes. Autotuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable length has changed since installation or when the motor and Drive have different capacities.
Trial Operation Procedures !Precautions for Rotational and Stationary Autotuning Lower the base voltage based on Fig 4.4 to prevent saturation of the Drive’s output voltage when the rated voltage of the motor is higher than the voltage of the power supply to the Drive. Use the following procedure to perform autotuning. 1. Input the voltage of the input power supply to T1-03 (Motor rated voltage). 2.

Frequency Reference This section explains how to input the frequency reference. " Selecting the Frequency Reference Source Set parameter b1-01 to select the frequency reference source.
Frequency Reference !Inputting the Frequency Reference Using Voltage (Analog Setting) When b1-01 is set to 1, you can input the frequency reference from control circuit terminal A1 (voltage input), or control circuit terminal A2 (voltage or current input). Inputting Master Speed Frequency Reference Only When inputting a voltage for the master speed frequency reference, input the voltage to control circuit terminal A1.
Switch between 2 Step Speeds: Master/Auxiliary Speeds When switching between the master and auxiliary speeds, connect the master speed frequency reference to control circuit terminal A1 or A2 and connect the auxiliary speed frequency reference to terminal A3. The reference on terminal A1 or A2 will be used for the Drive frequency reference when the multi-function input allocated to multi-speed command 1 is OFF and the reference on terminal A3 will be used when it is ON.
Frequency Reference " Using Multi-Step Speed Operation With Varispeed-G7 series Drives, you can change the speed to a maximum of 17 steps, using 16 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.
Setting Precautions When setting analog inputs to step 1 to step 3, observe the following precautions. • When setting terminal A1's analog input to step 1, set b1-01 to 1, and when setting d1-01 (Frequency Ref- erence 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 1F (do not use analog inputs).
Run Command Run Command This section explains input methods for the run command. " Selecting the Run Command Source Set parameter b1-02 to select the source for the run command. !Related Parameters Name Parameter Number Display Run Command Selection b1-02 Run Source Control Methods Description Setting Range Factory Setting Change during Operation V/f V/f with PG Openloop Vector 1 Flux Vector Open Loop Vector 2 Selects the run command input source.
Performing Operations Using a 3-wire Sequence When any parameter from H1-01 to H1-10 (multi-function contact input terminals S3 to S12) is set to 0, terminals S1 and S2 are used for a 3-wire sequence, and the multi-function input terminal that has been set functions as a forward/reverse run command terminal. When the Drive is initialized for 3-wire sequence control with A1-03, multi-function input 3 becomes the input terminal for the forward/reverse run command.
Stopping Methods Stopping Methods This section explains methods of stopping the Drive. " Selecting the Stopping Method when a Stop Command is Sent There are four methods of stopping the Drive when a stop command is sent: • Deceleration to stop • Coast to stop • DC braking stop • Coast to stop with timer Set parameter b1-03 to select the Drive stopping method. A DC braking stop and coasting to a stop with a timer cannot be set for flux vector control.
Name Parameter Number b2-02 Setting Range Factory Setting Sets the DC injection braking current as a percentage of the Drive rated current. Note: The DC excitation current is determined by the setting in E2-03 when operating in flux loop vector control mode 0 to 100 50% No A A A No No Sets the time of DC injection braking at start in units of 0.01 seconds. 0.00 to 10.00 0.00sec No A A A A A 0.00 to 10.00 0.
Stopping Methods The operation after stopping depends on the setting of b1-05 when flux vector control is selected (A1-02 = 3). Run command OFF ON OFF Frequency reference via analog input E1-09 0 b1-05=0 (frequency reference) Run command turns OFF and zero speed control start when motor speed drops to b2-01.
!DC Braking Stop If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 2, a wait is made for the time set in L2-03 (Minimum Baseblock (BB) Time) and then the DC injection brake current set in b2-02 is sent to the motor to apply a DC injection brake to stop the motor. The DC injection brake time is determined by the set value in b2-04 and the output frequency when the stop command is input.
Stopping Methods " Using the DC Injection Brake Set parameter b2-03 to apply the DC injection brake voltage to the motor while it is coasting to a stop, to stop the motor and then restart it. Set b2-03 to 0 to disable the DC injection brake at start. Set the DC injection brake current using b2-02. DC injection braking is used at startup for flux vector control with the current set in E2-03 (Motor no-load current).
!Changing the DC Injection Brake Current Using an Analog Input If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog Input Terminal A3 Function Selection) to 6 (DC injection brake current), you can change the DC injection brake current level using the analog input. At 10Vinput (voltage) or 20mA input (current), 100% of the Drive rated current will be applied. DC injection brake voltage level Drive rated current Fig 6.
Acceleration and Deceleration Characteristics Acceleration and Deceleration Characteristics This section explains the acceleration and deceleration characteristics of the Drive. " Setting Acceleration and Deceleration Times Acceleration time indicates the time taken for the output frequency to climb from 0% to 100%. Deceleration time indicates the time taken for the output frequency to reduce to 0%.
Name Parameter Number C1-11 Acc/Dec SW Freq S-Curve Characteristic at Accel End SCrv Acc @ End C2-03 Setting Range Factory Setting Sets the frequency for automatic switching of accel / decel times. Fout < C1-11: Accel/Decel Time 4 Fout ≥ C1-11: Accel/Decel Time 1 Multi-function inputs "Multi-Acc/Dec 1" and "Multi-Acc/Dec 2" have priority over C1-11. Note: with Multi-Function Input, Accel/Decel Time 1 and 2 will take precedence. 0.0 to 400.0 *1 0.0Hz No A A A A A 0.00 to 2.50 0.
Acceleration and Deceleration Characteristics !Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal Commands Using the Drive, you can set four acceleration times and four deceleration times. 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.
Acceleration/deceleration time gain (set value: 5) (Acceleration/deceleration gain from 1 to 10 V) = 10 V/Input voltage (V) x 10 (%) Fig 6.19 Acceleration/Deceleration Time Gain Using an Analog Input !Entering S-curve Characteristics in the Acceleration and Deceleration Time By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and stopping the machine.
Acceleration and Deceleration Characteristics " Accelerating and Decelerating Heavy Loads (Dwell Function) The dwell function stores the output frequency when starting or stopping heavy loads. By temporarily storing the output frequency, you can prevent the motor from stalling. When using the dwell function, you must select a deceleration stop. Set b1-03 (Stopping Method Selection) to 0.
" Preventing the Motor from Stalling During Acceleration (Stall Prevention During Acceleration Function) The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed on the motor, or sudden rapid acceleration is performed. If you set L3-01 to 1 (enabled) and the Drive output current exceeds the -15% level of the set value in L3-02, the acceleration rate will begin to slow down. When L3-02 is exceeded, acceleration will stop.
Acceleration and Deceleration Characteristics !Time Chart The following figure shows the frequency characteristics when L3-01 is set to 1. Output current Stall level during acceleration Time Output frequency Output frequency is controlled to prevent the motor stalling. Time Fig 6.
" Preventing Overvoltage During Deceleration (Stall Prevention During Deceleration Function) The Stall Prevention During Deceleration function makes the rate of deceleration more gentle to suppress increases in DC bus voltage when the DC bus voltage exceeds the set value during motor deceleration. This function automatically lengthens the deceleration time with respect to the bus voltage, even if the deceleration time has been set to a considerably small value.
Acceleration and Deceleration Characteristics !Setting Example An example of stall prevention during deceleration when L3-04 is set to 1 as shown below. Output frequency Deceleration time controlled to prevent overvoltage Time Deceleration time (set value) Fig 6.23 Stall Prevention During Deceleration Operation !Setting Precautions • The stall prevention level during deceleration differs depending on the Drive capacity. Refer to the follow- ing table for details.
Adjusting Frequency References This section explains methods of adjusting frequency references. " Adjusting Analog Frequency References Gain and bias are among the parameters used to adjust analog inputs.
Adjusting Frequency References Name Parameter Number Display Terminal A2 Signal Level Selection H3-08 Term A2 Signal H3-09 Terminal A2 Function Selection Terminal A2 Sel Terminal A2 Gain Setting H3-10 Terminal A2 Gain Terminal A2 Bias Setting H3-11 Terminal A2 Bias H3-12 Control Methods Description Setting Range Factory Setting Change during Operation Selects the signal level of terminal A2. 0: 0 to 10Vdc (switch S1-2 must be in the OFF position).
!Adjusting Frequency Gain Using an Analog Input When H3-09 or H3-05 is set to 1 (frequency gain), you can adjust the frequency gain using the analog input terminal A2 or A3. Frequency gain Multi-function analog input terminal A2 input level Fig 6.25 Frequency Gain Adjustment (Terminal A2 Input) The frequency gain for terminal A1 is the sum of H3-02 and terminal A2 gain. For example, when H3-02 is set to 100% and terminal A2 is set to 5 V, the terminal A1 frequency reference will be 50%.
Adjusting Frequency References For example, if H3-02 is 100%, H3-03 is 0%, and terminal A2 is set to 1 V, the frequency reference from terminal A1 when 0Vis input to A1 will be 10%. Frequency reference H3-02 10% Bias Terminal A1 input voltage 0V 10 V " Operation Avoiding Resonance (Jump Frequency Function) The jump frequency function operates the motor while avoiding resonance caused by characteristic frequencies in the machinery. This function is effective in creating a frequency reference dead band.
Output frequency Frequency reference descending Jump frequency width d3-04 Frequency reference ascending Jump frequency Jump width d3-04 frequency width d3-04 Jump frequency reference Jump frequency 3 (d3-03) Jump frequency 2 (d3-02) Jump frequency 1 (d3-01) Fig 6.
Adjusting Frequency References " Adjusting Frequency Reference Using Pulse Train Inputs The frequency reference can be adjusted when b1-01 (Reference Selection) is set to 4 (Pulse Train Input). Set the pulse frequency in parameter H6-02 to 100% reference, and then adjust the gain and bias accordingly using H6-03 and H6-04. !Related Parameters Name Parameter Number H6-01 Description Setting Range Factory Setting Selects the function of pulse train terminal RP.
Speed Limit (Frequency Reference Limit Function) This section explains how to limit the motor speed. " Limiting Maximum Output Frequency If you do not want the motor to rotate above a given frequency, use parameter d2-01. Set the upper limit value of the Drive output frequency as a percent, taking E1-04 (Maximum Output Frequency) to be 100%.
Speed Limit (Frequency Reference Limit Function) " Limiting Minimum Frequency If you do not want the motor to rotate at below a given frequency, use parameters d2-02 or d2-03. There are two methods of limiting the minimum frequency, as follows: • Adjust the minimum level for all frequencies. • Adjust the minimum level for the master speed frequency (i.e., the lower levels of the jog frequency, multistep speed frequency, and auxiliary frequency will not be adjusted).
Improved Operating Efficiency This section explains functions for improving motor operating efficiency. " Reducing Motor Speed Fluctuation (Slip Compensation Function) When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip compensation function controls the motor at a constant speed, regardless of changes in load.
Improved Operating Efficiency !Adjusting Slip Compensation Gain You can switch the C3-01 parameter settings as shown below by changing the control method. • V/f control without PG: 0.0 • Open-loop vector control: 1.0 • Flux vector control: 1.0 Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status. Adjust the slip compensation gain using the following procedure. 1. Set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current) correctly.
Slip compensation limit Output frequency E1-06: Base frequency E1-04: Maximum output frequency Fig 6.31 Slip Compensation Limit !Selecting Slip Compensation Function During Regeneration Set whether to enable or disable the slip compensation function during regeneration. If the slip compensation function operates during regeneration, you might have to use the braking option (braking resistor, Braking Resistor Unit, and Braking Unit) to momentarily increase the regenerative amount.
Improved Operating Efficiency " Compensating for Insufficient Torque at Startup and Low-speed Operation (Torque Compensation) The torque compensation function detects that the motor load has increased, and increases the output torque. V/f control calculates and adjusts the motor primary loss voltage according to the output voltage (V), and compensates for insufficient torque at startup and during low-speed operation.
!Adjusting Torque Compensation Gain Normally, there is no need to make this adjustment. Do not adjust the torque compensation gain when using open-loop vector control. Adjust the torque compensation gain using V/f control in the following circumstances. • If the cable is very long, increase the set value. • If the (maximum applicable) motor capacity is smaller than the Drive capacity, increase the set value. • If the motor is vibrating, reduce the set value.
Improved Operating Efficiency " Hunting-prevention Function The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function can be used in V/f without PG and V/f with PG. !Related Parameters Name Parameter Number n1-01 Description Factory Setting Change during Operation V/f V/f with PG Open Loop Vector 1 Flux Vector Open Loop Vector 2 If the motor vibrates while lightly loaded, hunting prevention may reduce the vibration.
" Stabilizing Speed (Speed Feedback Detection Function) The speed feedback detection control (AFR) function measures the stability of the speed when a load is suddenly applied, by calculating the amount of fluctuation of the torque current feedback value, and compensating the output frequency with the amount of fluctuation.
Machine Protection Machine Protection This section explains functions for protecting the machine. " Reducing Noise and Leakage Current The switching frequency of the Drive’s output transistor can be changed to reduce carrier noise and leakage current from the motor.
!Control Mode and Carrier Frequency Settings Carrier frequency settings are restricted as listed in the following table according to the control mode selection. Control Mode V/f control with or without a PG Open-loop vector control 1 or Flux vector control Open-loop vector control 2 Carrier Frequency 1: 2.0 kHz 2: 5.0 kHz 3: 8.0 kHz 4: 10.0 kHz 5: 12.5 kHz 6: 15.0 kHz F: Any setting* Detailed settings are available in C6-03, C6-04, and C6-05. 1: 2.0 kHz 2: 5.0 kHz 3: 8.0 kHz 4: 10.0 kHz 5: 12.
Machine Protection • With vector control, the carrier frequency is fixed to the Carrier Frequency Upper Limit in C6-03 if user- set or by the carrier frequency set in C6-02. • To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0. • If the settings are as shown below, OPE11 (Parameter setting error) will occur. If Carrier Frequency Proportional Gain (C6-05) > 6 and C6-03 < C6-04. • Depending on the carrier frequency setting, the Drive’s overload level may be reduced.
" Limiting Motor Torque (Torque Limit Function) The motor torque limit function is enabled only with open-loop torque control. In the open-loop vector control method, the user-set value is applied to the torque limit by calculating internally the torque output by the motor. Enable this function if you do not want a torque above a specified amount to be applied to the load, or if you do not want a regeneration value above a specified amount to occur.
Machine Protection !Setting the Torque Limit in Parameters Using L7-01 to L7-04, you can set individually four torque limits in the following directions: Forward drive, reverse drive, forward regeneration, and reverse regeneration. !Set the Torque Limit Value Using an Analog Input You can change the analog input level torque limit value by setting the torque limit in multi-function analog input terminals A2 and A3.
!Setting Precautions • When the torque limit function is operating, control and compensation of the motor speed is disabled because torque control is given priority. • When using the torque limit to raise and lower loads, do not carelessly lower the torque limit value, as this may result in the motor falling or slipping. • Torque limits using an analog input are the upper limit value (during 10Vor 20mA input) of 100% of the motor rated torque.
Machine Protection " Changing Stall Prevention Level during Operation Using an Analog Input If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog Input Terminal A3 Function Selection) to 8 (stall prevention level during run), you can change the stall level during operation by setting H3-10 (Gain (Terminal A2)) and H3-11 (Bias (Terminal A2)) or H3-06 (Gain (Terminal A3)) and H3-07 (Bias (Terminal A3).

Use this setting for applications in which reverse motor rotation can cause problems (e.g., fans, pumps, etc.
Continuing Operation Continuing Operation This section explains functions for continuing or automatically restarting Drive operation even if an error occurs. " Restarting Automatically After Power Is Restored Even if a temporary power loss occurs, you can restart the Drive automatically after power is restored to continue motor operation. To restart the Drive after power is restored, set L2-01 to 1 or 2. If L2-01 is set to 1, when power is restored within the time set in L2-02, the Drive will restart.
!Related Parameters Name Parameter Number Control Methods Description Setting Range Factory Setting Change during Operation Enables and disables the momentary power loss function. 0: Disabled - Drive trips on (UV1) fault when power is lost.
Continuing Operation " Speed Search The speed search function finds the actual speed of the motor that is rotating using inertia, and then starts smoothly from that speed. When restoring power after a temporary power loss, the speed search function switches connection from the commercial power supply, and then restarts the fan that is rotating using inertia.

Sets the time to approximately 0.7 times the motor secondary circuit time parameter. When an overcurrent or overvoltage occurs when starting a speed search or DC injection braking, increase the set values.
Continuing Operation !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 may 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, the Unit will start from the fre- quency detected by PG.
!Speed Search Selection Set whether to enable or disable speed search at startup, and set the type of speed search (estimated speed or current detection) using setting b3-01. To perform speed search when inputting the run command, set b3-01 to 1 or 3. Search Name Search Method Estimated Speed Current Detection Estimates the motor speed when the search starts, and accelerates and decelerates from the estimated speed to the set frequency. You can also search including direction of motor rotation.

Continuing Operation " Continuing Operation at Constant Speed When Frequency Reference Is Lost The frequency reference loss detection function continues operation using 80% speed of the frequency reference before loss when the frequency reference using an analog input is reduced 90% or more in 400ms.
" Restarting Operation After Transient Error (Auto Restart Function) If a Drive error occurs during operation, the Drive will perform self-diagnosis. If no error is detected, the Drive 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. If an error not listed below occurs, the protection function will operate and the auto restart function will not.
Drive Protection Drive Protection This section explains the functions for protecting the Drive and the braking resistor. " Performing Overheating Protection on Mounted Braking Resistors Perform overheating protection on Drive-mounted braking resistors (Model: ERF-150WJ ##). When overheating in a mounted braking resistor is detected, an alarm RH (Mounted braking resistor overheating) is displayed on the Digital Operator, and the motor coasts to a stop.
" Reducing Drive Overheating Pre-Alarm Warning Levels The Drive detects the temperature of the cooling fins using the thermistor, and protects the Drive from overheating. You can receive Drive overheating pre-alarms in units of 10°C. The following overheating pre-alarm warnings are available: Stopping the Drive as error protection, and continuing operation, with the alarm OH (Radiation fins overheating) on the Digital Operator flashing.
Input Terminal Functions Input Terminal Functions This section explains input terminal functions, which set operating methods by switching functions for the multi-function contact input terminals (S3 to S12). " Temporarily Switching Operation between Digital Operator and Control Circuit Terminals You can switch the Drive run command inputs and frequency reference inputs between local (i.e., Digital Operator) and remote (input method using b1-01 and b1-02).
" Blocking Drive Outputs (Baseblock Commands) Set 8 or 9 (Baseblock command NO/NC) in one of the parameters H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection) to perform baseblock commands using the terminal's ON/OFF operation, and prohibit Drive output using the baseblock commands. Clear the baseblock command to restart the operating using speed search from frequency references from the previous baseblock command input.
Input Terminal Functions " Stopping Acceleration and Deceleration (Acceleration/Deceleration Ramp Hold) The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output frequency at that point in time, and then continues operation.
!Application Precautions • When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If performing operations using this frequency after the Drive has also been turned OFF, input the run command with the Acceleration/Deceleration Ramp Hold turned ON. • When d4-01 is set to 0 and a run command is input while the Acceleration/Deceleration Ramp Hold is turned ON, the output frequency will be set to zero.
Input Terminal Functions !Precautions When setting and using UP and DOWN commands, observe the following precautions. Setting Precautions If multi-function input terminals S3 to S12 are set as follows, operation error OPE03 (Invalid multi-function input selection) will occur: • Only either the UP command or DOWN command has been set. • UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.
Output frequency Upper limit Accelerates to lower limit Same frequency Lower limit Forward operation/stop UP command Reference frequency reset DOWN command Frequency matching signal* Power supply * The frequency matching signal turns ON when the motor is not accelerating/ decelerating while the run command is ON.

Input Terminal Functions " Accelerating and Decelerating Constant Frequencies in the Analog References (+/- Speed) The +/- speed function increments or decrements the frequency set in analog frequency reference d4-02 (+/Speed Limit) using two contact signal inputs. To use this function, set One of the parameters H1-01 to H1-10 (multi-function contact terminal inputs S3 to S12 function selection) to 1C (Trim Control Increase command) and 1D (Trim Control Decrease command).
" Hold Analog Frequency Using User-set Timing When one of H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection) is set to 1E (sample/hold analog frequency command), the analog frequency reference will be held from 100ms after the terminal is turned ON, and operation will continue thereafter at that frequency. The analog value 100ms after the command is turned ON is used as the frequency reference. Sample/hold command Analog input Frequency reference Fig 6.
Input Terminal Functions !Setting Precautions To switch command inputs between the Communications Option Card and the control circuit terminals, set the following parameters. • Set b1-01 (Reference Selection) to 1 (Control circuit terminal [analog input]) • Set b1-02 (Operation Method Selection to 1 (Control circuit terminal (sequence inputs]) • Set one of the parameters H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selec- tion) to 2 (Option/Drive selection).
" Stopping the Drive by Notifying Programming Device Errors to the Drive (External Fault Function) The external fault function performs the error contact output, and stops the Drive operation if the Drive peripheral devices break down or an error occurs. The digital operator will display EFx (External fault [input terminal Sx]). The x in EFx shows the terminal number of the terminal that input the external fault signal. For example, if an external fault signal is input to terminal S3, EF3 will be displayed.

Individual Functions This section explains the individual functions used in special applications. " Using MODBUS Communications You can perform serial communications with MEMOCON-series Programmable Controllers (PLCs) or similar devices using the MODBUS protocol. !MODBUS Communications Configuration MODBUS 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 slave responds.
Individual Functions !Communications Connection Terminal MODBUS communications use the following terminals: S+, S-, R+, and R-.

MODBUS communications can perform the following operations regardless of the settings in b1-01 and b1-02. • Monitoring operation status from the PLC • Setting and reading parameters • Resetting errors • Inputting multi-function commands An OR operation is performed between the multi-function commands input from the PLC and commands input from multi-function contact input terminals S3 to S7. !Message Format In MODBUS communications, the master sends commands to the slave, and the slave responds.
Individual Functions Error Check Errors are detected during communications using CRC-16. Perform calculations using the following method. 1. The factory setting for CRC-16 communications is usually 0, but when using the MODBUS system, set the factory setting to 1 (i.e., set all 16 bits to 1). 2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data. 3. Also calculate CRC-16 for response messages from the slaves, and compare them to the CRC-16 in the response messages.
Loopback Test The loopback test returns command messages directly as response messages without changing the contents to check the communications between the master and slave. You can set user-defined test code and data values. The following table shows a message example when performing a loopback test with the slave 1 Drive.
Individual Functions Set the number of data specified using command messages as quantity of specified messages x 2. Handle response messages in the same way.

!Self-Diagnosis The Drive has a built-in function for self-diagnosing the operations of serial communications interface circuits. This function is called the self-diagnosis function. The self-diagnosis function connects the communications parts of the send and receive terminals, receives the data sent by the Drive, and checks if communications are being performed normally. Perform the self-diagnosis function using the following procedure. 1.
Individual Functions " Using the Timer Function Multi-function contact input terminals S3 to S7 can be designated as timer function input terminals, and multifunction output terminals M1-M2, M3-M4, and M5-M6 can be designated as timer function output terminals. By setting the delay time, you can erase chattering from the sensors and switches. • Set one of the parameters H1-01 to H1-10 (multi-function contact input terminal S3 to S12) to 18 (timer function input).
" Using PID Control PID control is a method of making the feedback value (detection value) match the set target value. By combining proportional control (P), integral control (I), and derivative control (D), you can even control targets (machinery) with play time. The characteristics of the PID control operations are given below. P control Outputs the amount of operation proportional to the deviation. You cannot, however, set the deviation to zero using P control alone.

Output of the PID regulator as a percentage of maximum frequency (E1-04).
!PID Control Methods There are four PID control methods. Select the method by setting parameter b5-01. Set Value Control Method 1 PID output becomes the Drive output frequency, and D control is used in the difference between PID target value and feedback value. 2 PID output becomes the Drive output frequency, and D control is used in the PID feedback value.
Individual Functions !PID Adjustment Methods Use the following procedure to adjust PID while performing PID control and measuring the response waveform. 1. Set b5-01 (PID Control Mode Selection) to 1 or 2 (PID control enabled). 2. Increase b5-02 (Proportional Gain (P)) to within a range that does not vibrate. 3. Reduce b5-03 (Integral (I) time) to within a range that does not vibrate. 4. Increase b5-05 (Derivative (D) time) to within a range that does not vibrate.
Suppressing Short Cycle Vibration If vibration occurs when the vibration cycle is short, and the cycle is almost identical to the derivative time (D) set value, the differential operation is too strong. Shorten the derivative time (D) to suppress the vibration. If vibration continues even when the derivative time (D) is set to 0.00 (D control disabled), reduce the proportional gain (P), or increase the PID primary delay time constant.

!PID Feedback Loss Detection When performing PID control, be sure to use the PID feedback loss detection function. If PID feedback is lost, the Drive output frequency may accelerate to the maximum output frequency. When setting b5-12 to 1 and the status of the PID feedback value detection level in b5-13 is insufficient and continues for the time set in b5-14, an FbL (PID feedback reference lost) alarm will be displayed on the Digital Operator and Drive operation will continue.

Protective and Diagnostic Functions " Errors During Autotuning The errors that can occur during autotuning are given in the following table. If an error is detected, the motor will coast to a stop and an error code will be displayed on the Digital Operator. The error contact output and alarm output will not function. Table 7.4 Errors During Autotuning Display Meaning Probable causes Corrective Actions Data Invalid Motor data error There is an error in the data input for autotuning.
Table 7.4 Errors During Autotuning (Continued) Display Meaning Corrective Actions V/f Over Setting V/f settings excessive* The torque reference exceeded 100% and the no-load torque exceeded 70% during autotuning. • Check and correct the settings. • Disconnect the load from the motor.
Protective and Diagnostic Functions " Errors when Using the Digital Operator Copy Function The errors that can occur when using the copy function from the Digital Operator are given in the following table. An error code will be displayed on the Digital Operator. If a Digital Operator key is pressed when an error code is being displayed, the display will be cleared and 03-01 will be displayed. The error contact output and alarm output will not function. Table 7.
Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Drive and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures. If the contents of the fault are displayed, refer to Protective and Diagnostic Functions. " If Parameters Cannot Be Set Use the following information if an Drive parameter cannot be set. !The display does not change when the Increment and Decrement Keys are pressed.
Troubleshooting " If the Motor Does Not Operate Use the following information if the motor does not operate. !The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Drive is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to display the drive mode, and enter the drive mode by pressing the DATA/ENTER Key. “-Rdy-” will be displayed when drive mode is entered.
The operation method selection is wrong. If parameter b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation. In that case press the LOCAL/REMOTE Key* again to return to the original setting.
Troubleshooting " If the Direction of the Motor Rotation is Reversed If the motor operates in the wrong direction, the motor output wiring is faulty. When the Drive T1(U), T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a forward run command is executed. The forward direction depends on the manufacturer and the motor type, so be sure to check the specifications.
" If the Motor Operates Higher Than the Reference Use the following information if the motor operates higher than the reference. !The analog frequency reference bias setting is wrong (the gain setting is wrong). The frequency reference bias set in parameter H3-03 is added to the frequency reference. Check to be sure that the set value is suitable. !A signal is being input to the frequency reference (current) terminal A1.
Troubleshooting " If Motor Deceleration is Slow Use the following information when the motor deceleration is slow. !The deceleration time is long even when braking resistor is connected. The following causes are possible. “Stall prevention during deceleration enabled” is set. When braking resistor is connected, set parameter L3-04 (Stall Prevention Selection during Deceleration) to 0 (disabled) or 3 (with braking resistor).
" If the Motor Overheats Take the following steps if the motor overheats. !The load is too big. If the motor load is too heavy and the motor is used with the effective torque exceeding the motor's rated torque, the motor will overheat. Some motor rating are given for short period performance and are not continuous ratings. Reduce the load amount by either lightening the load or lengthening the acceleration/deceleration time. Also consider increasing the motor capacity.
Troubleshooting " If the Ground Fault Interrupter Operates When the Drive is Run The Drive performs internal switching, so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more), or one that incorporates high frequency countermeasures (i.e.
!Oscillation and hunting are occurring with V/f w/PG control. The gain adjustment may be insufficient. Adjust the various types of speed control loop (ASR) gain. If the oscillation cannot be eliminated in this way, set the hunting prevention selection (parameter n1-01) to 0 (disabled) and then try adjusting the gain again. !Oscillation and hunting are occurring with flux vector control. The gain adjustment is insufficient. Adjust the various gains for speed control (ASR).
Troubleshooting " If Output Frequency Does Not Rise to Frequency Reference Use the following information if the output frequency does not rise to the frequency reference. !The frequency reference is within the jump frequency range. When the jump frequency function is used, the output frequency does not change within the jump frequency range. Check to be sure that the Jump Frequency (parameters d3-01 to d3-03) and Jump Frequency Width (parameter d3-04) settings are suitable.

Table 10.1 provides an overview of the control modes and their features. Table 10.
Varispeed G7 Control Modes Table 10.
!Application Function Precautions Observe the following precautions when using the application functions. • Perform rotational autotuning during trial operation whenever it is possible to separate the motor and machine. To achieve the characteristics of vector control described in Table 10.1, the control must be adjusted within a range that the machine will not vibrate after rotational autotuning has been performed. • With vector control, the motor and Drive must be connected 1:1.
Varispeed G7 Control Modes Load torque (%) 200 Driving torque 100 Speed (Hz) 0 1 3 6 60 0.3 -100 Regenerative torque -200 With torque control, operate within a speed control range of 1:10 on the regenerative side. Precautions on Setting Parameters If the parameters are not set properly, performance may be adversely affected. • If there is a possibility of starting with the motor already rotating, enable the speed search function (b3- 01=1).
" Control Modes and Applications !V/f Control without PG (A1-02 = 0) V/f control without a PG is suitable for applications where multiple motors are operated with a single Drive, such as with multi-motor drives. (Thermal relay) M1 Inverter M2 M3 Fig 10.1 !V/f Control with PG (A1-02 = 1) V/f control with a PG enables precise control of machine line speed. Speed control using the speed feedback of the machine shaft is possible in this mode.
Drive Application Precautions Drive Application Precautions This section provides precautions for selecting, installing, setting, and handling Drives. " Selection Observe the following precautions in selecting Drive. !Installing Reactors A large peak current will flow in the power input circuit when the Drive is connected to a large-capacity power transformer (600 kVA or higher) or when switching a phase capacitor. Excessive peak current can destroy the convertor section.
" Installation Observe the following precautions when installing Drive. !Installation in Enclosures Either install the Drive in a clean location not subject to oil mist, airborne matter, dust, and other contaminants, or install the Drive in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Drive does not go beyond the allowable temperature. Do not install the Drive on wood or other combustible materials.
Drive Application Precautions " Handling Observe the following precautions when wiring or performing maintenance for Drive. !Wiring Check The Drive will be internally damaged if the power supply voltage is applied to output terminal U/T1, V/T2, or W/T3. Check wring for any mistakes before supplying power. Check all wiring and sequences carefully. !Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line.
Motor Application Precautions This section provides precautions for motor application. " Using the Drive for an Existing Standard Motor When a standard motor is operated with the Drive, power loss is slightly higher than when operated with a commercial power supply. Observe the following precautions when using Drive for an existing standard motor. !Low Speed Ranges Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature.
Motor Application Precautions " Using the Drive for Special Motors Observe the following precautions when using a special motor. !Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Drive according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped.
