Acknowledging faults
The list of faults and alarms specifies how each fault is acknowledged after the cause has
been remedied.
1. Acknowledgment of faults with "POWER ON"
– Switch the drive unit on/off (POWER ON).
2. Acknowledgment of faults with "IMMEDIATE"
– 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"
3. Acknowledgment of faults with "PULSE INHIBIT"
– The fault can only be acknowledged with a pulse inhibit (r0899.11 = 0).
– The same options are available for acknowledging as described under
acknowledgment with IMMEDIATE.
Note
The drive cannot resume operation until all active faults have been acknowledged.
