C5-07 ASR Gain
Switchover
(0221)
Frequency
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.
Note:
An MFDI set for H1-xx = 77 [MFDI Function Select = ASR Gain (C5-03) Select] will have priority over the ASR gain switching
frequency.

C5-12 Integral Operation @
Accel/Decel
(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.

Expert
When A1-02 = 3 or 7 [Control Method Selection = CLV or CLV/PM], the drive automatically sets C5-17 to the
value of [Motor Inertia] when you do Inertia Tuning or ASR Tuning.
■
C5-18: Load Inertia Ratio
No.
Name
(Hex.)
C5-18 Load Inertia Ratio
(0277)
Expert
When A1-02 = 3 or 7 [Control Method Selection = CLV or CLV/PM], the drive automatically sets C5-18 to the
load inertia ratio when you do Inertia Tuning or ASR Tuning.
