Slip Compensation Gain Sets the gain for the slip compensation function. Usually it is not necessary to change this setting.
Note:
Correctly set these parameters before changing the slip compensation gain:
• E2-01 [Motor Rated Current (FLA)]
• E2-02 [Motor Rated Slip]
• E2-03 [Motor No-Load Current]
