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 you change the slip compensation gain:
When A1-02 = 2 [Control Method Selection = Open Loop Vector], you can use
Auto-Tuning to set E2-02 [Motor Rated Slip].
–E2-01 [Motor Rated Current (FLA)]
–E2-02 [Motor Rated Slip]
–E2-03 [Motor No-Load Current]
• When A1-02 = 4 [Advanced Open Loop Vector], you cannot change the setting
while the drive is running.
