Rated Slip Frequency of Motor

Factory Setting: 0.00

Settings 0.00~20.00Hz Unit: 0.01

 This parameter is to set rated slip of loaded motor. Users need to input rated rotation speed according

to nameplate of loaded motor. If rated frequency of motor is 60Hz, number of motor poles is 4 and

rated rotation speed of motor is 1650rpm. The rated slip frequency of motor is 60Hz-(1650rpm X

4/120) = 5Hz.

 This parameter has relation with 07-04 slip compensation. To have the best slip compensation, this

parameter must be set correctly. Incorrect setting may cause above functions disable and even

damage the motor and AC drive.

Auto Torque Compensation Gain



Factory Setting: 0.0

Settings 0.0~10.0 Unit: 0.1

 This parameter is to set auto torque compensation gain.

 When motor loading is high, a part of output frequency of AC drive will be absorbed by impedance

of stator winding to make voltage of exciting inductance of motor is not enough. Therefore, the short

of gap magnet field will make a high output current but low output torque. Auto torque

compensation gain could adjust output voltage automatically according to loading to maintain in a

fixed gap magnet of the motor to get the best running situation.

 If the setting of compensation gain is too great, over-exciting magnet will cause the following

situation: output current of AC drive is too great, motor is over-heating or protection function occurs.

Torque Compensation Gain by Manual Operation



Factory Setting: 0.0

Settings 0.0~10.0 Unit: 1.0

 This parameter determines torque compensation gain by manual operation.

 Torque compensation gain by manual operation won’t refer to the loading situation and adds

compensation voltage on the setting V/f curve. Basically, it just changes V/f curve. It could be

reached by adjusting V/f curve.

Calculate Total Running Time of the Motor (Min)

Factory Setting: 00

Settings 00 to 1439 Min Unit: 1

07 - 09

Calculate Total Running Time of the Motor (Day)

Factory Setting: 00

Settings 00 to 65535 Day Unit: 1

 This parameter could display running time of the motor.
