Simple Data Setting Digital setting (Refer to 5. OPERATING THE INVERTER) and potentiometer setting are both available for simple accel/decel operation of the VS-606V7. Digital setting is set at the factory (n004=1). For the model with digital operator (with potentiometer) JVOP-140, factory setting is set by frequency setting potentiometer (n004=0). Following is an example in which the function LED’s are used to set frequency reference, acceleration time, deceleration time, and motor direction.
6. PROGRAMMING FEATURES Factory settings of the constants are shown as in the tables. Constant Set-up and Initialization Constant selection/initialization (n001) The following table describes the data which can be set or read when n001 is set. Unused constants among n001 to n179 are not displayed.
Using V/f Control Mode V/f control mode is preset at the factory. Control mode selection (n002)= 0: V/f control mode (initial setting) 1: Vector control mode Adjusting torque according to application Adjust motor torque by using “V/f pattern” and “full-range automatic torque boost”. • V/f pattern setting Set V/f pattern by n011 to n017 as described below. Set each pattern when using a special motor (high-speed motor, etc.) or when requiring special torque adjustment of machine.
• Typical setting of V/f pattern Set the V/f pattern according to the application as described below. For 400V class, the voltage values (n012, n015, and n017) should be doubled. When running at a frequency exceeding 50Hz/60Hz, change the maximum output frequency (n011). Note :Be sure to set the maximum output frequency according to the motor characteristics.
• Full-range automatic torque boost (when V/f mode is selected; n002=0) Motor torque requirement changes according to load conditions. Fullrange automatic torque boost adjusts voltage of V/f pattern according to the requirement. The VS-606V7 automatically adjusts the voltage during constant-speed operation as well as during acceleration. The required torque is calculated by the inverter. This ensures tripless operation and energy-saving effects.
Using Vector Control Mode Setting the control mode selection (n002) can use a vector control mode. n002 = 0: V/f control mode (factory setting) 1: Vector control mode Precaution for voltage vector control application Since vector control needs motor constants, the YASKAWA standard motor constants have been set at the factory prior to shipment.

Notes : 1. When UP/DOWN command is selected, the upper limit speed is set regardless of frequency reference. Upper limit speed = Maximum output frequency (n011) Frequency reference upper limit (n033)/100 2. Lower limit value is either minimum output frequency (n016) or frequency reference lower limit (n034) (whichever is larger.). 3. When the FWD (REV) run command is input, operation starts at the lower limit speed without an UP/DOWN command. 4.
Using multi-function analog input ( n077, n078, n079 ) The input analog signal (0 to 10V or 4mA to 20mA) for the CN2 terminal of the JVOP-140 digital operator can be used as an auxiliary function for the main speed frequency reference input to the control circuit terminals (FR or RP). Refer to the block diagram on page111 for details of the input signal.

Frequency Reference by Pulse Train Input Frequency reference can be set by pulse train input from the multi-function input terminal. • Input pulse specifications • Low-level voltage: 0.8V or less • High-level voltage: 3.5 to 32V • H duty: 30 to 70% • Pulse frequency: 0 to 33 kHz • Frequency reference method Frequency reference is a value obtained by multiplying the ratio of the maximum input pulse frequency and actual input pulse frequency by the maximum output frequency.
Preventing Motor from Stalling (Current Limit) Automatically adjusts the output frequency and output current according to the load to continue operation without stalling the motor. • Stall prevention (current limit) level during acceleration (n093) Sets the stall prevention (current limit) level during acceleration in units of 1%. (Inverter rated current = 100%) Factory setting: 170% A setting of 200% disables the stall prevention (current limit) during acceleration.
• Stall prevention (current limit) level during running (n094) Sets the stall prevention (current limit) level during running in units of 1%. (Inverter rated current = 100%) Factory setting: 160% A setting of 200% disables the stall prevention (current limit) during running. If stall prevention action current at agreed speed exceeds the value set for n094 for longer than 100msec, deceleration starts. When the output current exceeds the value set for n094, deceleration continues.
n115 Setting Setting 0 Function The stall prevention level becomes the level set for the constant n094 in all frequency areas. The following shows that the stall prevention level is automatically decreased in the constant output range (Max. frequency>Max. voltage output frequency). The lower limit is 40% of the set value of n094. Constant output area Operation level 1 Operation level = n094 x max.
Decreasing Motor Speed Fluctuation Slip compensation ( When n002 is set to 0 ) As the load becomes larger, motor speed is reduced and motor slip value is increased. The slip compensating function controls the motor speed at a constant value even if the load varies. When inverter output current is equal to the motor rated current (n036), the compensation frequency is added to the output frequency.
Motor Protection Motor overload detection The VS-606V7 protects against motor overload with a built-in electronic thermal overload relay. • Motor rated current (elctronic thermal reference current, n036) Set to the rated current value shown on the motor nameplate. Note : Setting to 0.0A disables the motor overload protective function.
• General-purpose motor and inverter motor Induction motors are classified as general-purpose motors or inverter motors, based on their cooling capabilities. Therefore, the motor overload function operates differently between these two motor types. Example of 200V class motor Cooling Effect General-purpose Motor Effective when operated at 50/60Hz from commercial power supply.
Selecting Cooling Fan Operation In order to increase lifetime, the cooling fan can be set to operate only when inverter is running. n039 = 0 (Initial setting) : Operates only when inverter is running (Continues operation for 1 minute after inverter is stopped.) = 1 : Operates with power ON Using MEMOBUS (MODBUS) Communications Serial communication is available with VS-606V7 using programmable controller (MEMOCON series) and MEMOBUS. Refer to MEMOBUS Instruction Manual (Manual No.: TOEZ-C736-70.

Message format For communications, the master (PLC) sends a command to the slave (VS-606V7) and the slave responds to it. The configuration for sending and receiving is as shown to the right. The length of the data varies according to the contents of commands (functions). The interval between messages must be maintained at the following amount.
• Read out holding register contents [03H] Reads out the contents of the holding registers with the continuous numbers for the specified quantity. The contents of holding register is divided into the upper 8 bits and the lower 8 bits. They become the data items in response message in the order of numbers. (Example) Reads out status signal, fault contents, data link status and frequency reference from the VS-606V7 (slave 2).
• Writing to several holding registers [10H] Specified data are written into the several specified holding registers from the specified number, respectively. Written data must be arranged in a command message in the order of the holding register numbers: from upper eight bits to lower eight bits. (Example) Set forward run at frequency reference 60.0 Hz to slave 1 VS-606V7 from the PLC.

VS-606V7 is 100,000; do not execute the ENTER command excessively. When a constant is changed from the digital operator, the constant data on the RAM is written to the non-volatile memory without ENTER command. Register number 0900H is used only for write-in. If this register is readout, register number error (error code: 02H) occurs. Error Codes Error Code 01H 02H 03H 21H 22H Contents Function code error • Function code from PLC is other than 03H, 08H or 10H.
Performing self-test VS-606V7 is provided with a function to perform self-diagnosis for operation check of the serial communication I/F circuit. This function is called self-test. In the self-test, connect the sending terminal with the receiving terminal in the communication section. It assures if the data received by VS-606V7 is not being changed. It also checks if the data can be received normally. Carry out the self-test in the following procedure. 1. Turn ON the VS-606V7 power supply.
Using Energy-saving Control Mode Verify that the constant n002 is set to 0 (V/f control mode) when performing energy-saving control. Setting n139 to 1 enables the energysaving control function. Energy-saving Control Selection (n139) Constant No. Name Unit Setting Range Initial Setting n139 Energy-saving control selection – 0 : Disabled 1 : Enabled 0 Normally it is not necessary to change the setting.
• Energy-saving voltage lower / upper limit (n141, n142, n159, n160) Sets the upper and lower limits of the output voltage. When the value calculated in the energy-saving control mode is larger than the upper limit (or smaller than the lower limit), the value is output as a voltage reference value. The upper limit is set to prevent over-excitation, and the lower limit is set to prevent stalls when the load is light. The voltage limit is set for machines using 6Hz/60 Hz.
Energy-saving search operation In the energy-saving control mode, the max. applicable voltage is calculated using the output power. However, a temperature change or the use of another manufacturer’s motor will change the fixed constants, and the max. applicable voltage may not be emitted. In the search operation, change the voltage slightly so that the max. applicable voltage can be obtained. • Search operation Voltage Limit (n144) Limits the range where the voltage can be controlled.
• Search operation power detection hold width (n161) When the power fluctuation is less than this value, the output voltage is held for 3 seconds. Then, the search operation mode is activated. Set the hold width in % of the power which is currently held.

Using Constant Copy Function Constant copy function The VS-606V7 standard digital operator JVOP-140 can store constants for one inverter. A backup power supply is not necessary since EEPROM is used. Constant copy function is possible only for the inverters with same product series, power supply specifications and control mode (V/f control or vector control). However, some constants may not be copied. It is also impossible to copy constants between VS-606V7 and VSmini J7 inverters.

Reading is not possible when this constant is set to 0. The constant data stored in the digital operator are safe from accidental overwriting.
READ function Reads out the constants in batch from the inverter and stores them in EEPROM inside the digital operator. When the read-out is executed, the previously stored constants data in the EEPROM are cleared and replaced with the newly entered constants.

Undertorque Detection An alarm signal can be output to a multi-function output terminal (MA, MB, P1, or P2) when the load on the machine side suddenly becomes lighter (i.e., when an undertorque occurs). To output an undertorque detection signal, set the output terminal function selection in n057, n058, or n059 to 8 (undertorque detected, NO contact) or 9 (undertorque detected, NC contact).
Underorque detection level (n118) Sets the undertorque detection current level in units of 1%. (Inverter rated current = 100%) when detected by torque is selected, motor rated torque becomes 100%. Initial setting = 10% Undertorque detection time (n119) If the time for which the motor current is less than the undertorque detection level (n118) is longer than the undertorque detection time (n119), the undertorque detection function operates.

Troubleshooting Trouble Cause The motor does not operate when an external operation signal is input. The operation method selection is wrong. The run command (n003) is not set to Control Circuit Terminal. Set the run command (n003) to Control Circuit Terminal. Corrective Actions A 3-wire sequence is in effect. The multi-function input method (n052) is set to 3-wire sequence,and the S2 control terminal is not closed.
Trouble The motor speed is unstable. The motor speed fluctuates when operating with a light load. Cause Corrective Actions The stall prevention level during running is too low. Because the stall prevention level during running (n094) is too low, the output current reaches the set level and the speed drops. Check if the stall prevention level during running (n094) is set to an appropriate value. The load is too heavy.
