Trio Motion Technology MC4N-ECAT - Manual (Page 7)

An internal relay may be used to
enable external amplifi ers when the
controller has powered up correctly
and the system and application
software are ready. The amplifi 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 an axis error exists OR
the user program sets it open with
the WDOG=OFF command.
EtherCAT drives will be enabled via the EtherCAT network so the
“Amplifi er Enable” connection is not normally required.
All non EtherCAT stepper and servo amplifi ers MUST be inhibited
when the amplifi er enable output is open circuit
An additional safety relay may be required so as to meet
machine safety approvals.
