Group 7: Motor Parameters

 

 

 

 

 

 

 

 

7-00

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.

 

 

 

 

 

 

 

 

 

7-01

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

7-02

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.

7-03

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.
