◆ C3: SLIP COMPENSATION
The Slip Compensation function improves the speed accuracy of an induction motor. As loads on induction
motors increase, motor slip increases and motor speed decreases. By adjusting the output frequency in accordance
with the motor load, it compensates the slip and makes the motor speed equal to the frequency reference.
■ C3-01: Slip Comp Gain
No.
(Hex.)
Name Description
Default
(Range)
C3-01
(020F)
RUN
Slip Comp Gain
Sets the gain for the slip compensation function. Usually it is not necessary to change this setting.
Determined by A1-02
(0.0 - 2.5)
Note:
Correctly set these parameters before changing the slip compensation gain:
• E2-01 [Mot Rated Current (FLA)]
• E2-02 [Mot Rated Slip]
• E2-03 [Mot No-Load Current]
Adjust this parameter as follows if necessary:
• If the motor speed is slower than the frequency reference, increase this parameter in 0.1-unit increments.
• If the motor speed is slower than the frequency reference value, decrease this parameter value in 0.1-unit
increments.
■ C3-02: Slip Comp Delay Time
No.
(Hex.)
Name Description
Default
(Range)
C3-02
(0210)
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.
Determined by A1-02
(0 - 10000 ms)
Use these settings to adjust this parameter as necessary:
• When the speed is not stable, increase the setting.
• When the slip compensation response is too slow, decrease the setting.
