The following 3 basic para. can be automatically adjusted according to the setting value of the operating speed response (basic para. 33).

Basic para. 37 to 39 can be automatically rewritten only when the “auto” has been selected in the tuning method (basic para. 31).
Remark :
The values of basic para. 37 to 39 are rewritten once the operating speed response (basic para. 33) is changed.
Basic para. 37 to 39 can also be set manually after these have been changed by the amplifier. Usually amplifier set value is
used.

Changeover of response rate
The motor response rate can be changed over between when the motor is rotating and when the motor is stopping. This is effective to
reduce the noise when stopping and suppress the resonance with the mechanical equipment system.

Remarks : “Operating speed response” and “speed response at stoppage” should be changed after the speed has been lower than the
stoppage detection width (basic para. 35) and the stoppage judgment time (basic para. 36) has elapsed. This can prevent the
motor shaft from starting rotating after the motor has stopped if the setting of “speed response at stoppage” is low. Set an
appropriate time for the stoppage judgment time as its initial value is 0.0s.

Speed feedback filter
When you use 16 bit serial encoder in GYC or GYS series, do not change the setting of the speed feedback filter.
