Group 7: Motor Parameters
07.00 Motor Rated Current Unit: 1
Settings 30% FLA to 120% FLA Factory Setting: FLA
Use the following formula to calculate the percentage value entered in this parameter:
(Motor Current / AC Drive Current) x 100%
with Motor Current=Motor rated current in A on type shield
AC Drive Current=Rated current of AC drive in A (see Pr.00.01)
07.01 Motor No-load Current Unit: 1
Settings 0% FLA to 90% FLA Factory Setting: 0.4*FLA
The rated current of the AC drive is regarded as 100%. The setting of the Motor no-load
current will affect the slip compensation.
The setting value must be less than Pr.07.00 (Motor Rated Current).
07.02 Torque Compensation Unit: 0.1
Settings 0.0 to 10.0 Factory Setting: 0.0
This parameter may be set so that the AC drive will increase its voltage output to obtain a
higher torque.
Too high torque compensation can overheat the motor.
07.03 Slip Compensation Unit: 0.01
Settings 0.00 to 10.00 Factory Setting: 0.00
While driving an asynchronous motor, increasing the load on the AC motor drive will cause an
increase in slip and decrease in speed. This parameter may be used to compensate the slip by
increasing the output frequency. When the output current of the AC motor drive is bigger than
the motor no-load current (Pr.07.01), the AC drive will adjust its output frequency according to
this parameter.
