6. NORMAL GAIN ADJUSTMENT
POINT
In the torque control mode, you do not need to make gain adjustment.
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. In addition, 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.
For the vibration suppression control tuning mode, the setting range of [Pr.
PB07] is limited. For the vibration suppression control tuning mode, the setting
range of [Pr. PB07] is limited. Refer to section 7.1.5 (4) for details.
