Remote Trip Alarm
The Remote trip alarm is designed to signal a network fault to the drive. When using the
Modbus Plus interface, all outputs are set to zero on link fail. If one of the outputs is REM
SEQUENCE [536] the drive will trip after a delay specified by REM TRIP DELAY (541). The
Drive will then need a low - > high transition on ACK Alarm and Start before the drive may run
again.
