9. GENERAL GAIN ADJUSTMENT
9. GENERAL GAIN ADJUSTMENT
POINT
Before making gain adjustment, check that your machine is not being
operated at maximum torque of the servo motor. If operated over maximum
torque, the machine may vibrate and may operate unexpectedly. Make gain
adjustment with a safety margin considering characteristic differences of each
machine. It is recommended that generated torque during operation is under
90% of the maximum torque of the servo motor.
9.1 Different adjustment methods
9.1.1 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.
