C3-21: Motor 2 Slip Compensation Gain
n
Improves speed accuracy for motor 2 and functions in the same way that C3-01 functions for motor 1. Adjust this
parameter only after setting the motor rated current (E4-01), motor rated slip (E4-02), and the motor no-load current
(E4-03).
Adjustments might be needed in the following circumstances:
• Increase C3-21 if the motor at constant speed is slower than the frequency reference.
• Decrease C3-21 if the motor at constant speed is faster than the frequency reference.

C3-23: Motor 2 Slip Compensation Limit
n
Sets the upper limit for the slip compensation function as a percentage of the motor rated slip (E4-02).
No.
C3-23 Motor 2 Slip Compensation Limit
The slip compensation limit is constant throughout the constant torque range (frequency reference
constant power range (frequency reference > E3-06), it is increased based on C3-23 and the output frequency as
illustrated in Figure 2.26.
