Speed response is slow.
Overshoot or undershoot occurs at the end of acceleration
or deceleration.
Vibration and oscillation occur at constant speed.

C5-01 ASR Proportional Gain 1
(021B)
RUN
A higher gain provides a higher speed response. Usually, the gain increases with larger loads. Too much gain will
cause vibration.
Note:
• The drive usually sets Motor 1 ASR with C5-01 and C5-02 [ASR Integral Time 1]. You can set H1-xx = 77 [MFDI Function Selection =
ASR Gain (C5-03) Select] to switch between C5-01 and C5-03 [ASR Proportional Gain 2] . You can also use C5-01 and C5-02 as
alternatives to C5-03 and C5-04, respectively, when the speed is less than or equal to the frequency set in C5-07 [ASR Gain Switchover
Frequency].
• The drive automatically adjusts C5-01 in ASR Tuning.

C5-02: ASR Integral Time 1
No.

(Hex.)
C5-02 ASR Integral Time 1
(021C)
RUN
When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
■
C5-03: ASR Proportional Gain 2
No.
Name
(Hex.)
C5-03 ASR Proportional Gain 2
(021D)
RUN
A higher gain provides a higher speed response. Usually, the gain increases with larger loads. Too much gain will
cause vibration.
