A50020 (F)

PNCOMM BOARD: Second controller missing

Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: CBE20:
The PROFINET function "Shared Device" has been activated (p8829 = 2). However, only the connection to a
PROFINET controller is present.
See also: p8829 (CBE2x remote controller number)
Remedy: CBE20:
Check the configuration of the PROFINET controllers as well as the p8829 setting.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
F60004 (N, A)

Armature circuit phase failure detected

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: Phase failure in armature infeed.
The line voltage rms value calculated from the area of each line half-wave (rectifier average value * harmonic factor)
is less than the response value for phase failure monitoring or the distance between two line zero crossings in the
same phase is more than 270 degrees or the distance between two line zero crossings in different phases is not
between 30 and 90 degrees.
- Phase failure threshold set incorrectly (p50353)
- Armature phase failed
- Line contactor opened in operation
- Fuse blown on three-phase side of armature circuit
- Fuse blown in power unit
Fault value (r0949, interpret decimal):
1:
Power failure has occurred in armature infeed (UV, VW, WU)
r50047[1] = 0: First power failure in armature phase UV
r50047[1] = 1: First power failure in armature phase VW
r50047[1] = 2: First power failure in armature phase WU
r50047[2]: Incorrect voltage value as a % of p50078[0]
2:
Wait time for new zero crossing has expired in one armature phase (UV, VW, WU)
r50047[1] = 0: No zero crossing in armature phase UV in excess of 270 °
r50047[1] = 1: No zero crossing in armature phase VW in excess of 270 °
r50047[1] = 2: No zero crossing in armature phase WU in excess of 270 °
r50047[2]: Time without zero crossing (= duration 270 °) of armature phase r50047[1] in ms
3:
Line asymmetry in armature infeed (UV, VW, WU)
r50047[1]: Phase number of phase of last zero crossing (0 = UV, 1 = VW, 2 = WU)
r50047[2]: Phase number of phase of last-but-one zero crossing (0 = UV, 1 = VW, 2 = WU)
r50047[3]: Time of last raw zero crossing in ms
r50047[4]: Time of last-but-one raw zero crossing in ms
r50047[5]: Time of last positive refined zero crossing in phase UV in ms
r50047[6]: Time of last negative refined zero crossing in phase UV in ms
r50047[7]: Time of last positive refined zero crossing in phase VW in ms
r50047[8]: Time of last negative refined zero crossing in phase VW in ms
r50047[9]: Time of last positive refined zero crossing in phase WU in ms
