6. GENERAL GAIN ADJUSTMENT
POINT
Consider differences among machines, and adjust the gain. It is recommended that
the amount of torque generated from the servo motor in operation be set to 90 of
the maximum torque of the servo motor.
The torque loop mode does not require the gain adjustment.
6.1 Different adjustment methods
6.1.1 Adjustment on a single servo amplifier
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 results, execute auto tuning mode 2 and manual mode in
this order.
