C3-18: Output Voltage Limit Level
■
Sets the maximum percentage of output voltage reduction when C3-05 is enabled.
No.
C3-18
C3-21: Motor 2 Slip Compensation Gain
■
Used to improve speed accuracy for motor 2. Functions in the same way that C3-01 functions for motor 1.
Adjust this parameter only after the motor rated current (E4-01), motor rated slip (E4-02), and the motor no-load current
(E4-03) have all been set.
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.
No.

C3-22: Motor 2 Slip Compensation Primary Delay Time
■
Functions for motor 2 in the same way that C3-02 functions for motor 1.
Refer to C3-02: Slip Compensation Primary Delay Time on page 126

C3-23: Motor 2 Slip Compensation Limit
■
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 shown in
Figure 2.25.
