2.5.15. Connecting a Limit switch override push button
DANGER!
The Limit switch override is used to disconnect safety limitations. Make sure the Limit switch
override function is not active longer than absolutely necessary.
If the option SafeMove is implemented, Limit switch override must never be used at all. The
SafeMove safety controller has its own override function.
General
The override circuit enables the possibility to jog an axis out of a forbidden (limited) zone.
Limitations
The switch has to be placed inside the controller to eliminate the risk of electrical noise.
