Useful Bit Patterns using SEQ STATUS
Tag 537, Mnemonic "ox" (Read Only) - for example:
Sequence Status Comment
0x1B0B Running
0x044B Tripped, Run High
0x0447 Tripped, Run Low, Enable Low
0x0C47 Trip Acknowledged, Healthy output TRUE Alarm stays high until drive is restarted.
Drive Enable
To Enable the drive in remote mode the following diagnostic must be TRUE:
REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 1.
Drive Start
To Start the drive in remote mode the following diagnostic must be TRUE:
REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 0.
Drive Jog
To Jog the drive in remote mode the following diagnostic 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 diagnostic must be TRUE:
REM.SEQ.ENABLE[535] and REM SEQUENCE [536] BIT 4.
ACK Alarm
Alarms are latched while ACK ALARM is FALSE.
To Acknowledge an alarm when in Remote Sequencing, use REM. SEQUENCE [536] BIT 8.
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).
