■ C5-21: Motor 2 ASR Proportional Gain 1
No.
(Hex.)
Name Description
Default
(Range)
C5-21
(0356)
RUN
Motor 2 ASR
Proportional Gain 1
Sets the gain to adjust ASR response for motor 2.
Determined by E3-01
(0.00 - 300.00)
The speed response increases as the weight of the load increases. Usually, the gain increases with larger loads.
Too much gain causes 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] as an alternative to C5-21 when the speed is less than or equal to the frequency set in C5-27 [Motor 2 ASR Gain
Switchover Freq]. To use C5-23 as an alternative to C5-21, set H1-xx = 77 [MFDI Function Select = ASR Gain (C5-03) Select].
• The drive automatically adjusts C5-21 in ASR Tuning.
■ C5-22: Motor 2 ASR Integral Time 1
No.
(Hex.)
Name Description
Default
(Range)
C5-22
(0357)
RUN
Motor 2 ASR Integral
Time 1
Sets the ASR integral time for motor 2.
Determined by E3-01
(0.000 - 60.000 s)
An integral time that is too long will decrease the responsiveness of the speed control and decrease drive response
to dynamic changes in motor load. 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] as an alternative to C5-22 when the speed is less than or equal to the frequency set in C5-27 [Motor 2 ASR Gain
Switchover Freq].
■ C5-23: Motor 2 ASR Proportional Gain 2
No.
(Hex.)

RUN
Motor 2 ASR
Proportional Gain 2
Sets the gain to adjust ASR response for motor 2.

(0.00 - 300.00)
The speed response increases as the weight of the load increases. Usually, the gain increases with larger loads.
Too much gain causes vibration.
■ C5-24: Motor 2 ASR Integral Time 2
No.
(Hex.)
Name Description
Default
(Range)
C5-24
(0359)
RUN
Motor 2 ASR Integral
Time 2
Sets the ASR integral time for motor 2.
Determined by E3-01
(0.000 - 60.000 s)
An integral time that is too long will decrease the responsiveness of the speed control and decrease drive response
to dynamic changes in motor load. 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 can also be used 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].
