Speed control (ASR) proportional gain switch (switching between C5-01 and C5-03)
OFF: Use proportional gain in C5-01
ON: Use proportional gain in C5-03
No No No Yes Yes
At zero-speed, increase C5-01
(ASR P Gain 1) until there is no oscillation.
At zero-speed, decrease C5-02
(ASR I Time 1) until there is no oscillation.
Does oscillation develop when the motor
operates at the maximum normal operating
speed?
Decrease C5-01 (ASR P Gain 1).
Increase C5-02 (ASR I Time 1).
YES
NO
Adjustment completed.
(When there is higher-level position control,
adjust the position loop gain so that
overshooting/undershooting doesn’t occur.)
