12.4 C: Tuning
When A1-02 = 3 or 7 [Control Method Selection = CLV or CLV/PM], the drive automatically sets C5-18 to the
load inertia ratio when you do Inertia Tuning or ASR Tuning.

C5-21 Motor 2 ASR Proportional
Gain 1
(0356)
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 2 ASR with C5-21 and C5-22 [Motor 2 ASR Integral Time 1]. You can also use C5-23 [Motor 2 ASR
Proportional Gain 2] instead of C5-21 when the speed is less than or equal to the frequency set in C5-27 [Motor 2 ASR Gain
Switchover Freq]. You can switch between C5-21 and C5-23 by setting H1-xx = 77 [MFDI Function Selection = ASR Gain (C5-03)
Select].
• The drive automatically adjusts C5-21 in ASR Tuning.

When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
Note:
The drive usually sets Motor 2 ASR with C5-21 [Motor 2 ASR Proportional Gain 1] and C5-22. You can also use C5-24 [Motor 2 ASR
Integral Time 2] instead of C5-22 when the speed is less than or equal to the frequency set in C5-27 [Motor 2 ASR Gain Switchover
Freq].

When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
Note:
The drive usually sets Motor 2 ASR with C5-21 [Motor 2 ASR Proportional Gain 1] and C5-22 [Motor 2 ASR Integral Time 1]. You can
also use C5-24 [Motor 2 ASR Integral Time 2] instead of C5-22 when the speed is less than or equal to the frequency set in C5-27
