7.4 Gain switching function
Gain switching operation is performed through internal data or external signal:
1) Can switch to lower gain to suppress vibration in the state when the motor is stopped;
2) Can switch to higher gain to shorten the positioning time in the state the motor is stop;
3) Can switch to high gain to obtain better command follow -up performance in the state when the
motor is running.
4) Can switch between different gain settings through external signal according to the conditions of
load, equipment and so on.
