7. GENERAL GAIN ADJUSTMENT
7. GENERAL GAIN ADJUSTMENT
POINT
Consider individual machine differences, and do not adjust gain too strictly. It is
recommended to keep the servo motor torque to 90
or less of the maximum
torque of the servo motor during the operation.
For use in the torque control mode, you need not make gain adjustment.
7.1 Different adjustment methods
7.1.1 Adjustment on a single driver
The gain adjustment in this section can be made on a single driver. For gain adjustment, first execute auto
tuning mode 1. If you are not satisfied with the results, execute auto tuning mode 2 and manual mode in this
order.
