5-41

5.8 Group 7: Motor Parameters

7 - 00 Motor Rated Current Factory Setting: d 85

Settings d 30 to d 120% Unit: 1%

This parameter can be set during operation.



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

overheating.

7 - 01 Motor No-load Current Factory Setting: d 50

Settings d 0 to d 90% Unit: 1%

This parameter can be set during operation.



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 Factory Setting: d 1

Settings d 0 to d 10 Unit: 1

This parameter can be set during operation.



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 Factory Setting: d 0.0

Settings d 0.0 to d 10.0 Unit: 0.1

This parameter can be set during operation.

 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.
