10.3.5 Automatic Gain Switching Function
The automatic gain switching function switches the gain setting between the gain setting 1 and 2 according to the
condition:
Whether position reference is specified or not, or
Position error level, or
AND logic of the above two conditions
The position reference of the automatic gain switching condition indicates the reference pulses from CN1.
Note that the automatic gain switching function is disabled for the control modes other than position control.
And, the real-time autotuning function is disabled while gain setting 2 is selected.
The existing gain switching function by /G-SEL signal is also available. However, it cannot be used with the
automatic gain switching function.
Note that automatic gain switching function is enabled only in position control mode. In the control modes other
than position control, gain setting 1 is used.
When the automatic gain switching is enabled by setting 1 to 3 of Pn10B.2, the gain switching function by /G-
SEL signal is disabled.
