Slip Compensation Gain

Sets the gain for the slip compensation function. Usually it is not necessary to change this setting.

Note:

•

When

A1-02 = 4 [AOLV]

, you cannot change the setting while the drive is running.

•

Correctly set these parameters before you change the slip compensation gain:

–

E2-01 [Motor Rated Current (FLA)]

–

E2-02 [Motor Rated Slip]

–

E2-03 [Motor No-Load Current]

Slip Compensation Delay
Time

Sets the slip compensation delay time when speed is unstable or when the slip compensation
response is too slow. Usually it is not necessary to change this setting.
