4 Faults and alarms
4.2 List of faults and alarms
Note 2:
For SINAMICS DCM with 2 CUD, the following applies:
After carrying out a reset (p0972 > 0 or p0976 = 200) at a CUD, then this fault is output at the other. In this case, the
fault has no significance and can be acknowledged.
Remedy:
Check the power supply.
Reaction upon N:
NONE
Acknowl. upon N:

System utilization high

Message value:
-
Message class:
General drive fault (19)
Drive object:
DC_CTRL
Reaction:
NONE
Acknowledge:
NONE
Cause:
The average computing time utilization (r9976[1]) for the system is greater than 95 %.
Remedy:
Reduce computing time utilization by.
The following options are available to do this:
- check the number of cyclically calculated blocks (DCC), and if required reduce.
- assign DCC blocks to runtime groups with a longer sampling time.
- check the number of cyclically calculated function blocks (FBLOCKS), and if required reduce.
- assign function blocks to runtime groups with a longer sampling time.
- remove DRIVE-CLiQ components that are not required.
- deactivate control blocks that are not required (p50899). This must be especially taken into account for a CUD right.
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowl. upon F:
IMMEDIATELY
Reaction upon N:
NONE
Acknowl. upon N:
NONE
F60099 (N, A)

System utilization too high

Message value:
-
Message class:
General drive fault (19)
Drive object:
DC_CTRL
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The average computing time utilization (r9976[1]) for the system is greater than 100 %.
Note:
r50047[1]: Averaged computing time utilization (in %)
r50047[2]: Maximum computing time utilization (in %)
Remedy:
Reduce computing time utilization by.
The following options are available to do this:
- check the number of cyclically calculated blocks (DCC), and if required reduce.
- assign DCC blocks to runtime groups with a longer sampling time.
- check the number of cyclically calculated function blocks (FBLOCKS), and if required reduce.
- assign function blocks to runtime groups with a longer sampling time.
- remove DRIVE-CLiQ components that are not required.
- deactivate control blocks that are not required (p50899). This must be especially taken into account for a CUD right.
