Trio Motion Technology MC206x - Manual (Page 5)

An internal relay is used to enable external amplifiers when the
controller has powered up correctly and the system and application
software are ready. The amplifier enable is a single pole solid state
relay with a normally open “contact”. The enable relay contact will
be open circuit if there is no power on the controller OR a following
error exists on a servo axis OR the user program sets it open with
the WDOG=OFF command.
ALL STEPPER AND SERVO AMPLIFIERS MUST BE INHIBITED WHEN
THE AMPLIFIER ENABLE OUTPUT IS OPEN CIRCUIT
ANALOGUE INPUT AIN0: 0 TO 10V
