Parameter Number
• High speed • If torque or speed response are slow, increase the
C5-01 [ASR PGain 1] setting value in increments of 5.00.
• Low speed • If hunting or oscillation occur, decrease the setting
C5-03 [ASR PGain 2] value.
• High speed • If torque or speed response are slow, decrease the
C5-02 [ASR ITime 1] setting value.
• Low speed • If hunting or oscillation occur, increase the setting
C5-04 [ASR ITime 2] value.
C5-07 [ASR Gain Switch Change the ASR proportional gain and ASR integral
Frequency] time to conform to the output frequency.
If the rigidity of the machine is unsatisfactory and
C5-06 [ASR Delay Time] vibration is possible, increase the setting value in
increments of 10 ms.
