Motor Rated Current 

Unit: 1

 

Settings 

d30 to d120% 

Factory Setting: d85

 

This parameter will limit the AC drive output current in order to prevent the motor from 

overheating. 

 

Motor No-load Current 

Unit: 1

 

Settings 

d0 to d90% 

Factory Setting: d50

 

The rated current of the AC drive is regarded as 100%.  Motor setting of no-load current will 

effect the slip compensation.  The setting value must be less than motor rated current setting 

Pr.7-00 

 

Torque Compensation 

Unit: 0.1

 

Settings 

d0 to d10 

Factory Setting: d1

 

This parameter may be set so that the AC drive will increase its voltage output during start-up 

to obtain a higher initial starting torque. 

 

Slip Compensation 

Unit: 0.01

 

Settings 

d0.0 to d10.0 

Factory Setting: d0.0

 

While driving an asynchronous motor, load on the AC drive will increase, causing an increase 

in slip. This parameter may be used to compensate the nominal slip within a range of 0 to 10. 

When the output current of the AC drive is greater than the motor no-load current (Pr.7-01), 

the AC drive will adjust its output frequency according to this parameter.
