■ C5-01: ASR Proportional Gain 1
No.
(Hex.)
Name Description
Default
(Range)
C5-01
(021B)
RUN
ASR Proportional Gain 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 Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F
Control)] to enable this parameter.
• The drive usually sets Motor 1 ASR with C5-01 and C5-02 [ASR Integral Time 1]. When you set H1-xx = 77 [MFDI Function Select =
ASR Gain Switch], you can switch between C5-01 and C5-03 [ASR Proportional Gain 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 Switchover
Frequency].
• The drive automatically adjusts C5-01 in ASR Tuning.
■ C5-02: ASR Integral Time 1
No.
(Hex.)
Name Description
Default
(Range)
C5-02
(021C)
RUN
ASR Integral Time 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 Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F Control)]
to enable this parameter.
■ C5-03: ASR Proportional Gain 2
No.
(Hex.)
Name Description
Default
(Range)
C5-03
(021D)
RUN
ASR Proportional Gain 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 Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F Control)]
to enable this parameter.
■ C5-04: ASR Integral Time 2
No.
(Hex.)
Name Description
Default
(Range)
C5-04
(021E)
RUN
ASR Integral Time 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 Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F Control)]
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 [Maximum Output Frequency] is 100%.
