This function does not affect the travel distance (i.e., the number of pulses).
6.1.3 Adjusting Gain
If speed loop gain or position loop gain exceeds the allowable limit for the servo
system (including the machine to be controlled), the system will tend to vibrate or
become too sensitive. Smooth operation is not possible under such conditions.
Reduce each loop gain value to an appropriate value.
Refer to 6.2.1 Setting Servo Gain for details regarding servo gain adjustment.
