Acknowledging faults
The list of faults and alarms specifies how to acknowledge each fault after the cause has been
removed.
Table 4-3 Acknowledging faults
Acknowledgment
POWER ON The fault is acknowledged by a POWER ON (switch drive unit off and on again).
Note
If this action has not eliminated the fault cause, the fault is displayed again immediately after power up.
IMMEDIATELY Faults can be acknowledged on one drive object (Points 1 to 3) or on all drive objects (Point 4) as
follows:
1 Acknowledge by setting parameter:
p3981 = 0 --> 1
2 Acknowledge via binector inputs:
p2103
p2104
p2105
3 Acknowledging via a PROFIdrive control signal:
STW1.7 = 0 --> 1 (edge)
4 Acknowledge all faults
p2102
All of the faults on all of the drive objects of the drive system can be acknowledged using this
binector input.
Note
• These faults can also be acknowledged by a POWER ON.
• If the cause of the fault has not been eliminated, the fault will continue to be displayed after
acknowledgment.
• Safety Integrated faults
The "Safe standstill" (SH) function must be deselected before these faults are acknowledged.
PULSE INHIBIT The fault can only be acknowledged when the pulses are inhibited (r0899.11 = 0).
The same options are available for acknowledging as described under acknowledge IMMEDIATELY.
Fault buffer - saved when switching off
The contents of the fault buffer are saved to the non-volatile memory when the Control Unit is
switched off, i.e. the fault buffer history is still available when the unit is switched on again.
The fault buffer of a drive object comprises the following parameters:
• r0945[0...63], r0947[0...63], r0948[0...63], r0949[0...63]
• r2109[0...63], r2130[0...63], r2133[0...63], r2136[0...63]
The fault buffer contents can be deleted manually as follows:
• Delete fault buffer for all drive objects:
• Delete fault buffer for a specific drive object:
