※ Note: Motor no load current (05-01) differs with the inverter capacities (12-00) (Refer to 06-01
note). It should be regulated according to actual conditions.
Group6- Motor parameter group
06-00 : Motor Rated Voltage (VAC)
06-01 : Motor Rated Current (Amp AC)
06-02 : Motor Rated Power (kW)
06-03 : Motor Rated Speed (RPM)
06-04 : Motor Rated Frequency (Hz)
06-06 : Torque boost gain (Vector)
Performance: If the motor load is determined to be too large increase the output torque.
(load current) (compensation gain)
• Torque/Speed curve pattern :
• Operating frequency range： 0~Motor rate frequency
• When the motor output torque is not enough and increase 06-06 setting value.
• When the motor is erratic or vibrates decrease 06-06 setting value.
• The max. Output torque limit to the inverter is current rated.
• If increase 06-06 setting value then the output current is too large. Please increase 06-07 setting
value on the same time.
