6.5.2 Gain switching
The gain switching function includes "Manual Gain Switching" which uses an external input signal and "Auto Gain
Switching" which switches automatically.
By using the gain switching function, you can increase gain and shorten positioning time during positioning, and decrease
gain and suppress vibration when the motor is stopped.
Fn No.
