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]
