C5-23: Motor 2 ASR Proportional Gain 2
No.

Description
Default

C5-23
(0358)
RUN
Motor 2 ASR Proportional
Gain 2
Sets the gain to adjust ASR response for motor 2.
Determined by E3-01
(0.00 - 300.00)
A higher gain provides a higher speed response. 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)
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 [Motor 2 ASR
Gain Switchover Freq]
.
■
C5-25: Motor 2 ASR Limit
No.

Description
Default

C5-25
(035A)
Motor 2 ASR Limit
Set the motor 2 ASR output limit as a percentage of
E1-04 [Maximum Output Frequency]
.
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 PG signal and these parameters before you make changes to
C5-25
.

C5-26: Motor 2 ASR Delay Time
No.
(Hex.)
Name
Description
Default
(Range)
C5-26
(035B)
Motor 2 ASR Delay Time
Sets the motor 2 filter time constant of the torque reference output from the speed loop. Usually it is
not necessary to change this setting.
Determined by E3-01
(0.000 - 0.500 s)
If you have a load with low rigidity or if oscillation is a problem, decrease
C5-21
in 2-unit decrements or decrease
C5-26
in 0.001-unit decrements.
■
C5-27: Motor 2 ASR Gain Switchover Freq
No.
(Hex.)
Name
Description
Default
(Range)
C5-27
(035C)
Motor 2 ASR Gain
Switchover Freq
Sets the frequency where the drive will switch between these parameters:
C5-21 and C5-23 [Motor 2 ASR Proportional Gain 1/2]
C5-22 and C5-24 [Motor 2 ASR Integral Time 1/2]
0.0
(0.0 - 400.0)
Switching the proportional gain and integral time in the low or high speed range can help operation become stable. A
good switching point is 80% of the frequency where oscillation occurs or at 80% of the maximum output frequency.
