2-28 Hardware Overview
Motion Coordinator MC206
Trio Motion Technology
I/O Connector 3
Amplifier Enable (Watchdog) Relay Output
An internal relay contact is used to enable external amplifiers when the control-
ler has powered up correctly and the system and application software is ready.
The amplifier enable is a single pole relay with a set of normally open contacts.
The enable relay contact will be open circuit if there is no power on the control-
ler OR a following error exists on a servo axis OR the user program sets it open
with the WDOG=OFF command.
The amplifier enable relay may, for example, be incorporated within a hold-up
circuit or chain that must be intact before a 3-phase power input is made live.

ALL STEPPER AND SERVO AMPLIFIERS MUST BE INHIBITED WHEN THE
