An internal relay is used to enable external amplif ers when the
controller has powered up correctly and the system and application
software are ready. The amplif er 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
