Acknowledgement of faults
The list of faults and alarms specifies how to acknowledge each fault after the
cause has been remedied.
Table 3-3 Acknowledgement of faults
List
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 Starting from a drive object, the fault can be acknowledged by the following methods:
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 is displayed again immedi-
ately after power up.
• Safety Integrated faults
The "Safe Stop" (SH) function must be deselected before these faults are acknowl-
edged.
READY The fault can be acknowledged only in the READY state.
In this state, the DC link is charged and the pulses disabled.
