large, the deviation pulse can be maintained without convergence.
4) Important points when using Gain 1 and Gain 2 in the position control mode
- Gain switching method by contact
: When sound is generated when the motor stops, select the contact to apply high gain in
normal operation and select the contact to apply low gain after motor stop.
- Gain switching method by speed
: The gain switching method by contact is aimed at setting low gain in the motor stop area,
while the speed gain switching method requires high-precision machining which requires
high gain at low speed and low gain at high speed. This can be used for machines.
- Gain switching method by torque
: If the gain is set high when the servo motor is operated with high torque, it may cause
vibration. In addition, when the servo motor is operated at low torque, the low gain causes
the speed ripple and control performance to deteriorate. In this case, by using the gain
switching method for torque, stable and excellent control performance can be realized in
the whole operating area.
