An internal relay may be 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 an axis error exists OR
the user program sets it open with
the WDOG=OFF command.
RTEX drives will be enabled via the RTEX network so the
“Amplifier Enable” connection is not normally required.
All non RTEX stepper and servo amplifiers MUST be inhibited
when the amplifier enable output is open circuit
An additional safety relay may be required so as to meet
machine safety approvals.
