Table 3-3 Acknowledgement of faults
Acknowledg-
ment
Description
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 at an individual drive object (Points 1 to 3) or at all drive
objects (point 4) as follows:
1 Acknowledge by setting parameter:
p3981 = 0 --> 1
2 Acknowledge via binector inputs:
p2103
p2104
p2105
BI: 1. Acknowledge faults
BI: 2. Acknowledge faults
BI: 3. Acknowledge faults
3 Acknowledge using PROFIBUS control signal:
STW1.7 = 0 --> 1 (edge)
4 Acknowledging all faults
p2102 BI: Acknowledging all faults
All of the faults at 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 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.
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.
