Parameter Number Possible Solutions
• If torque or speed response are
C5-01 [ASR Proportional Gain
slow, increase the setting value
1]
in increments of 5.00.
• If hunting or oscillation occur,
C5-03 [ASR Proportional Gain
decrease the setting value.
2]
• If torque or speed response are
C5-02 [ASR Integral Time 1] slow, decrease the setting value.
• If hunting or oscillation occur,
C5-04 [ASR Integral Time 2] increase the setting value.
Change the ASR proportional gain
and ASR integral time to conform
to the output frequency.
If the rigidity of the machine is
unsatisfactory and vibration is
possible, increase the setting value
in increments of 0.010.
Refer to the motor nameplate or
test report and set E1-xx or E5-xx
correctly.
