Motion Coordinator MC216
MC216 lower front panel
24v Power Supply Input
The MC216 is powered entirely via the 24v d.c.supply connections. The unit uses
internal DC-DC converters to generate independent 5v logic supply, the encoder
5v supply and other internal power supplies.
24V dc, Class 2 transformer or power source.
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.
Note:
ALL STEPPER AND SERVO AMPLIFIERS MUST BE INHIBITED WHEN THE
AMPLIFIER ENABLE OUTPUT IS OPEN CIRCUIT
