Drive Enable To Enable the drive in remote mode the following parameters must be
TRUE: REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 1.
Drive Start To Start the drive in remote mode the following parameters must be
TRUE: REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 0.
Drive Jog To Jog the drive in remote mode the following parameters must be
TRUE: REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 3.
Jog Mode To select the jog setpoint in remote mode the following parameters must be TRUE:REM.SEQ.ENABLE[535] and
REM SEQUENCE [536] BIT 4.
ACK Alarm To Acknowledge an alarm the following parameter must be TRUE:REM SEQUENCE [536] BIT 8.
Note: If remote sequencing is not enabled then REM SEQUENCE [536] BIT 8 is forced TRUE.
Remote Trip Alarm The Remote trip alarm is designed to signal a network fault to the drive. When using the Profibus 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.
REM TRIP INHIBIT [540]
REM TRIP DELAY [541] REMOTE TRIP [542]
Disable remote trip. Delay before trip becomes active after bit
being cleared.
Status of the Remote trip alarm, OK, Warning (Remote
Seq Bit 9 FALSE and delay not expired), Active (Trip
active, timer expired and remote not inhibited).
