Problem
Possible Solutions
If
C5-12 = 1
or
C5-32 = 1 [Enabled]
in Closed Loop V/f
Control, over/undershoot occurs when you change speeds.
-
•
Decrease
C5-01/C5-03
.
•
Increase
C5-02/C5-04
.
•
Decrease the value set to
C5-05
.
Oscillation at low speed and response is too slow at high
speed.
Oscillation at high speed and response is too slow at low
speed.
-
•
Closed Loop V/f Control Mode:
Use
C5-03
and
C5-04
at maximum speed and
C5-01
and
C5-02
at minimum speed to set different ASR settings.
•
Closed Loop Vector Control, PM Advanced Open Loop
Vector Control, and PM Closed Loop Vector Control:
Use
C5-01 to C5-04
to set the best ASR settings for high
and low speed. Use
C5-07 [ASR Gain Switchover
Frequency]
to switch the ASR proportional gain and
ASR integral time as specified by the output frequency.

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:
•
The drive usually sets Motor 1 ASR with
C5-01
and
C5-02 [ASR Integral Time 1]
. You can switch between
C5-01
and
C5-03 [ASR
Proportional Gain 2]
by setting
H1-xx = 77 [MFDI Function Selection = ASR Gain (C5-03) Select]
. 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.

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.
