9.4.9 Switching Gain Settings
Gain switching by the external signal is possible with the SGDH SERVOPACK. For example, to use different
gains while the servomotor is running or stopped, set two values in the gain settings 1 and 2 and switch the gains
by the external signal.
(1) Gain Switching Input Signal
(2) Switchable Gain Combinations
Turning ON and OFF the gain switching signal /G-SEL switches the gains as follows.
