Servo Responsiveness Setting - Mitsubishi Electric A173UHCPU Programming Manual

4. PARAMETERS FOR POSITIONING CONTROL
4.3.10

Servo responsiveness setting

(1) This parameter setting is used to increase servo responsiveness.
Changing the set value to a higher value in the sequence 1, 2..., 5 improves
servo responsiveness.
For machines with high friction, use the set values in the range 8 through C.
Response settings
1: Low-speed response
2:
3:
4:
5: High-speed response
8: Low-speed response
9:
A:
B:
C: High-speed response
(2) Increase the response setting step by step starting from the low-speed
response setting, observing the vibration and stop stabilization of the motor and
machine immediately before stopping as you do so. If the machine resonates,
decrease the set value.
If the load inertia is 5 times the motor inertia, make the set value 1 or more.
(3) The figure below shows how the motor's response changes according to the
servo responsiveness setting.
Command value
Change in motor response in accordance with response setting
(4) Change the servo responsiveness setting while the motor is stopped.
