Slip Comp 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 [Mot Rated Current (FLA)]
• E2-02 [Mot Rated Slip] (Set during Auto-Tuning when A1-02 = 2 [Control
Method = OLVector])
• E2-03 [Mot No-Load Current]

RUN
Slip Comp 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.
