Using Vector Control Mode - YASKAWA VS-606V7 Series Instruction Manual

• Using Vector Control Mode

Setting the control mode selection (n002) can use a vector control mode.
n002=0: V/f control mode (factory setting)
• Precaution for voltage vector control application
Since vector control needs motor parameters, the YASKAWA standard motor
parameters have been set at the factory prior to shipment. Therefore, when an
inverter exclusive-use motor is used or when a motor of any other manufacturer is
driven, the required torque characteristics or speed control characteristics may not
be maintained because the parameters are not matched. Set the following
parameters so that they can match the motor parameters.
No.
n106 Motor rated slip
n107 Motor resistance per phase=
n036 Motor rated current
n110 Motor no-load current
∗
Setting depends on inverter capacity.
To adjust for slip compensation gain (n111), induce load so that motor speed
reaches target value. Increase or decrease the value by 0.1.
• When speed is less than target value, increase slip compensation gain.
• When speed is more than target value, reduce slip compensation gain.
Adjustment of slip compensation gain time parameter (n112) is normally not
required.
Adjust under the following conditions:
• Reduce the setting when response is low.
• Increase the setting when speed is unstable.
