9.4.9 Switching Gain Settings

Gain switching functions by the external signal, or by using automatic gain switching that is enabled only at posi-

tion control, are built into the SGDM/SGDH SERVOPACK. For example, to use different gains while the servo-

motor is running or stopped, set two values in the gain settings 1 and 2 and switch the gains.
