Acknowledging faults
The list of faults and alarms specifies how to acknowledge each fault after the
cause has been remedied.
Table 3-3 Acknowledging faults
Acknowledge-
ment
POWER ON The fault is acknowledged by a POWER ON process (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 Acknowledge using PROFIBUS control signal:
STW1.7 = 0 --> 1 (edge)
Note:
• These faults can also be acknowledged by a POWER ON operation.
• If this action has not eliminated the fault cause, the fault will continue to be displayed
after acknowledgment.
• Safety Integrated faults
The "Safe Torque Off" (STO) function must be deselected before these faults are
acknowledged.
PULSE INHIBIT The fault can only be acknowledged with a pulse inhibit (r0899.11 = 0).
The same possibilities are available for acknowledging as described under acknowledge
IMMEDIATELY.
