C5-12 Integral@Ac/Dec Operation
No.

C5-12
Integral@Ac/Dec Operation
(0386)
If you enable integral operation when you are driving a heavy load or a high inertia load, it could cause problems
with overshoot or undershoot at the end of acceleration and deceleration. If there are problems with overshooting
and undershooting, set this parameter to
0 : Disabled
Integral operation is not enabled during acceleration or deceleration. Integral operation is always enabled during
constant speed.
1 : Enabled
Integral operation is always enabled.

When A1-02 = 3 or 7 [Control Method = CLVector or PM CLVector], the drive automatically sets C5-17 to the
value of [Control Method] when you do Inertia Tuning or ASR Tuning.

C5-18
Inertia Ratio of Load
(0277)
Expert
When A1-02 = 3 or 7 [Control Method = CLVector or PM CLVector], the drive automatically sets C5-18 to the
load inertia ratio when you do Inertia Tuning or ASR Tuning.
C5-21 M2 ASR PGain 1
No.
Name
(Hex.)
C5-21
M2 ASR PGain 1
(0356)
RUN
The speed response increases as the weight of the load increases. Usually, the gain increases with larger loads.
Too much gain causes vibration.
Note:
• The drive usually sets Motor 2 ASR with C5-21 and C5-22 [M2 ASR PGain 1 and M2 ASR ITime 1]. You can also use C5-23 [M2 ASR
PGain 2] as an alternative to C5-21 when the speed is less than or equal to the frequency set in C5-27 [M2 ASR Gain Switchover
Freq]. To use C5-23 as an alternative to C5-21, set H1-xx = 45 [MFDI Function Select = ASR Gain Switch].
• The drive automatically adjusts C5-21 in ASR Tuning.
C5-22 M2 ASR ITime 1
No.
Name
(Hex.)
C5-22
M2 ASR ITime 1
(0357)
RUN
An integral time that is too long will decrease the responsiveness of the speed control and decrease drive response
to dynamic changes in motor load. An integral time that is too short can cause oscillation.
