■ C5-01: ASR PGain 1
No.
(Hex.)
Name Description
Default
(Range)
C5-01
(021B)
RUN
ASR PGain 1
Sets the gain to adjust ASR response.
Determined by A1-02
(0.00 - 300.00)
A higher gain provides a higher speed response. Usually, the gain increases with larger loads. Too much gain will
cause vibration.
Note:
• When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
• The drive usually sets Motor 1 ASR with C5-01 and C5-02 [ASR ITime 1]. When you set H1-xx = 45 [MFDI Function Select = ASR
Gain Switch], you can switch between C5-01 and C5-03 [ASR PGain 2]. You can also use C5-01 as an alternative to C5-03 and C5-02
as an alternative to C5-04 when the speed is less than or equal to the frequency set in C5-07 [ASR Gain Switch Frequency].
• The drive automatically adjusts C5-01 in ASR Tuning.
■ C5-02: ASR ITime 1
No.
(Hex.)
Name Description
Default
(Range)
C5-02
(021C)
RUN
ASR ITime 1
Sets the ASR integral time.
Determined by A1-02
(0.000 - 60.000 s)
When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
Note:
When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
■ C5-03: ASR PGain 2
No.
(Hex.)
Name Description
Default
(Range)
C5-03
(021D)
RUN
ASR PGain 2
Sets the gain to adjust ASR response.
Determined by A1-02
(0.00 - 300.00)
A higher gain provides a higher speed response. Usually, the gain increases with larger loads. Too much gain will
cause vibration.
Note:
When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
■ C5-04: ASR ITime 2
No.
(Hex.)
Name Description
Default
(Range)
C5-04
(021E)
RUN
ASR ITime 2
Sets the ASR integral time.
Determined by A1-02
(0.000 - 60.000 s)
When you increase the integral time, the responsiveness will decrease. An integral time that is too short can cause
oscillation.
Note:
When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.
■ C5-05: ASR Limit
No.
(Hex.)
Name Description
Default
(Range)
C5-05
(021F)
ASR Limit
Sets the ASR output limit where E1-04 [Max Output Frequency] is 100%.
5.0%
(0.0 - 20.0%)
If the motor rated slip is high, it is necessary to increase the setting for correct motor speed control. Use U6-04
[ASR Output] to make sure that ASR is operating at the limit set in this parameter. When ASR is operating at the
limit, correctly set the encoder (PG) signal before you make changes to C5-05.
