Diagnostic Memory; Trend Recorder Function; Thyristor Test With P50830; Faults/Alarms - Siemens SINAMICS DCM 6RA80 Faq

Diagnostic memory: The diagnostic memory provides support in the case of
troubleshooting and handling problems experienced at the SINAMICS DCM. In this case,
diagnostic data is stored in a file format. A memory card is needed for saving the file. With
p50832 = 1, the file is copied to the memory card.
Send your recorded diagnostic file to: support.automation@siemens.com for evaluation.
See Section 10.33.1 of the Operating Instructions and Sheet 8052 from Section 2 of the List
Manual.
Trend recorder function: The trend recorder function enables data from 4 channels to be
recorded over an extended period with a large memory depth. A memory card is needed for
saving purposes.
The evaluation and visualization can be performed, for instance, with Excel.
See p51700 – p51706.
See Section 10.33.2 of the Operating Instructions and Sheet 8050 from Section 2 of the List
Manual

Thyristor test with p50830:

See Section 10.33.3 of the Operating Instructions
Perform a thyristor test with p50830 = 3. A test of the thyristors is run after the On command
(operating state o3.0). The thyristors are OK if the unit then starts operation without
disruptions.
The load (motor) on the SINAMICS DCM must be connected.
Note: The thyristor test does not return clear information on whether the thyristor cannot be
fired for all load states, particularly in the case of an inductive load.
The thyristor test cannot be applied in the event of series or parallel connection of SINAMICS
DCM.
Faults: See Sheet 8060, 8075 in Section 2 and Section 3 of the List Manual
Should a fault occur, Fxxxxx (xxxxx is the fault number) is displayed on the BOP20.
To change the fault reaction, see parameters p02100, p02101.
To change the type of message fault/alarm/no message: p02118, p02119
Acknowledge mode: p02126, p02127
In the case of a fault, bit 3 switches from status word 1 to high.
Acknowledge all faults via BI p2102. The source of the acknowledge command (BO) is
entered here. p2102 = 19.7 Acknowledge via the FN key at BOP20.
In the case of an alarm message, the diagnostic parameter r0949[0...63] must always be
read out.
See also parameters r0945, r0947, r 2109, r2130, r2133, r2136, r50047.
Current fault code in CO r02131.
Alarms: See Sheet 8065 in Section 2 and Section 3 of the List Manual
If an alarm occurs, Axxxxx (xxxxx is the number of the alarm) is displayed on the BOP20.
Bit 7 from status word 1 is set to high.
The occurrence of an alarm indicates a special state of the device, but does not initiate a
device response and has no effect on operation. The alarm message disappears
automatically when its cause has been eliminated.

Type of message fault/alarm: p02118, p02119
Current alarm code in the CO: r02132.
