7.1.6 Gain Select
Use the Gain Select function to meet performance requirements of varying loads. There are
di󰀨erent methods of using the Gain Select function. One of these is through an digital input.
Another is called automatic gain switching. These are explained in this section.
1) Increasing the gain can decrease and suppress vibration when doing position control.
2) Reducing the gain can decrease the settling time when the motor comes to a stop.
3) When the motor is running, increasing the gain can improve command following performance.
Example:
When the motor is running at low speed or stopped, a lower gain can be used to reduce noise,
but when the motor is running at high speed or positioning, switch to a higher gain to improve
command following performance.
