Note:
If you enable integral control, overshoot or undershoot can occur when acceleration or deceleration complete. If there are problems with
overshooting and undershooting, set this parameter to
0
.
0 : Disabled
Integral operation is always enabled during constant speed. The drive will not enable integral operation during
acceleration or deceleration.
1 : Enabled
Integral operation is always enabled.

When
A1-02 = 3 [Control Method Selection = Closed Loop Vector Control]
,
C5-17
is automatically set to the
value of
[Motor Inertia]

RUN
Motor 2 ASR Proportional
Gain 1
Sets the gain to adjust ASR response.
Determined by E3-01
(0.00 - 300.00)
The speed response increases with the weight of the load. Usually, the gain increases with larger loads. Excessive
gain causes vibration.
Note:
•
Motor 2 ASR is usually set using
C5-21 and C5-22 [Motor 2 ASR Integral Time 1]
. Parameter
C5-23
can also be used in place of
C5-
21
when the speed is less than or equal to the frequency set in
C5-27 [Motor 2 ASR Gain Switchover Freq]
.
•
C5-21
is automatically adjusted when the ASR Tuning process is executed.

RUN
Motor 2 ASR Integral Time
1
Sets the ASR integral time.
Determined by E3-01
(0.000 - 60.000 s)
An integral time that is too long decreases the responsiveness of the speed control and weakens repulsion against
external force. An integral time that is too short can cause oscillation.
Note:
CLV control is usually set using
C5-21 [Motor 2 ASR Proportional Gain 1]
and
C5-22 [Motor 2 ASR Integral Time 1]
. Parameter
C5-22
can also be used instead of
C5-24 [Motor 2 ASR Integral Time 2]
when the speed is less than or equal to the frequency set to
C5-27
[Motor 2 ASR Gain Switchover Freq]
