MELSERVO J2-Super 4 - 23
4.6 Gain
4.6.1 Gain adjustment
The gain adjustment in this section can be made on a single servo amplifier. For gain
adjustment, first execute auto tuning mode 1. If you are not satisfied with the movement
processes of the machine during operation, then carry out the following steps in the order that
they are specified:
● Auto tuning mode 2
● Manual setting of the gain factor 1
● Manual setting of the gain factor 2
The following table shows the items of the different gain setting methods:
