Slip Compensation Gain
0.0 to 2.5
Determined by A1-02
Note: When A1-02 = 0 (Open-Loop V/F Control), the default setting is 0.0. When A1-02 = 0 (Open-Loop Vector
Control), the default setting is 1.0.
 C5- 01 Slip Compensation Primary Delay Time
Sets the slip compensation primary delay time to stabilize the motor speed or to improve the
speed response. Normally there is no need to change this parameter. However, adjust the
setting in the following situations.
· Decrease the setting if the slip compensation response is too slow.
· Increase the setting if the motor speed is unstable.

The slip compensation limit is constant within the constant torque range (frequency command
≤ d1-04). In the output range (frequency command ≥ d1-04), it is increased based on the
setting in this parameter and the output frequency as shown in the following figure.
