● General properties of faults and alarms
Acknowledgement of faults
The list of faults and alarms specifies how each fault is acknowledged after the cause has
been remedied.
1. Acknowledgement of faults by "POWER ON"
2. Acknowledgement of faults by "IMMEDIATE"
3. Acknowledge faults with "PULSE INHIBIT"

– Must be acknowledged once the cause has been remedied.
– Status via Control Unit and LED RDY.
– Status via PROFIBUS status signal ZSW1.3 (fault active).
– Entry in the fault buffer.
– Are identified by Axxxxx.
– Have no further effect on the drive.
– The alarms are automatically reset once the cause has been remedied. No
acknowledgement is required.
– Status via PROFIBUS status signal ZSW1.7 (alarm active).
– Entry in the alarm buffer.
– Can be configured (e.g. change fault to alarm, fault reaction).
– Triggering on selected messages possible.
– Initiation of messages possible via an external signal.
– Switch the drive on/off (POWER ON)
– Press the RESET button on the Control Unit
– Via PROFIBUS control signal
STW1.7 (reset fault memory): 0/1 edge
Set STW1.0 (ON/OFF1) = "0" and "1"
– Via external input signal
Binector input and interconnection with digital input
p2103 = "Requested signal source"
p2104 = "Requested signal source"
p2105 = "Requested signal source"
Across all of the drive objects (DO) of a Control Unit
p2102 = "Requested signal source"
– The fault can only be acknowledged with a pulse inhibit (r0899.11 = 0).
– The same possibilities are available for acknowledging as described under
