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.

(a) Gain Switching Input Signal
(b) Switchable Gain Combinations
Turning ON and OFF the gain switching signal /G-SEL switches the gains as follows.
