24V must be applied to power the outputs, analogue inputs and
DAC outputs on the axis connector.
aMplifier enable (WatChdog) relay oUtpUt
An internal solid-state relay is used to enable external amplifiers
when the controller has powered up correctly and the system and
application software are ready. The enable relay contact will be open
circuit if there is no power on the controller OR the user program
sets it open with the WDOG=OFF command. Each axis also has an
independent enable relay which operates in tandem with the main
relay as determined by the application program. See MC4 range
technical manuals for details.
