SINAMICS DCM
1168 List Manual (LH8), 02/2015, 6RX1800-0ED76
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: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A60098 (F, 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.
