Diagnostics for some fault/alarm messages

Fault in the armature input circuit:

F60004 occurs

F60004 occurs whenever a device is switched on:
Evaluate fault value of F60004 acc. to Operating Instructions to locate the cause.
Check the following parameters:
p50078[0]: Rated voltage of supply network for the armature circuit (neither output voltage of
SINAMICS DCM nor rated motor voltage)
p50353: Response threshold of phase failure monitoring as a percentage of p50078[0]
p50086: Duration of voltage failure on automatic restart
p50089: Maximum waiting time for voltage on power unit
p50090: Stabilization time for line voltage
Observe setting instructions of parameter descriptions.
Check voltages of the armature circuit infeed:
Acknowledge pending alarm messages, set shutdown by opening terminal X177.12
Switch off field supply with p50082 = 0
Suppress F60004 with p02118 and p02119 (set to no message)
Switch on via terminal X177.12 but do not set operating enable via terminal X177.13
Operating state at r50000 must be between o4 and o1 (check r50000)
Operating state o4: Wait for voltage (armature)
Measure voltage with a voltmeter between all phases 1U1 / 1V1 / 1W1 directly at the device
input
r50015: Compare display of line voltage (armature) with measured voltage
If measured voltages are not OK:
Check line fuses
Measure voltage in front of and behind the main contactor
Measure voltage at the contactor coil.
Check output for the main contactor relay terminal 109/110.
If measured voltage is OK, but operating state o4 and r50015 still not OK:
The line voltage is recorded via the ignition cables for thyristors; check whether all are
correctly plugged in.
On devices with arm fuses (> 900 A rated DC current), check arm fuses.
If all checks are OK but still operating state o4:
Fault on the power interface module of the SINAMICS DCM
After diagnostics / repair, set p50082, p02118 and p02119 back to the original values.
F60004 occurs sporadically:
Evaluate fault value of F60004 acc. to Operating Instructions to locate the cause.
Check parameters as above. Check control of main contactor.
Perform trace recording with triggering in response to fault.

Field fault

F60005 occurs:

Evaluate fault value for F60005 to locate the cause
p50078[1]: Rated voltage of supply network for field circuit (neither output voltage of
SINAMICS DCM nor rated motor voltage for the field)
p50353: Response threshold of phase failure monitoring as a percentage of p50078[1]
p50351: Check undervoltage threshold, refers to p50078[1]
p50352: Check overvoltage threshold, refers to p50078[1]
p50086: Duration of voltage failure on automatic restart
Observe setting instructions of parameter descriptions.
Check voltages of field circuit infeed 3U1 / 3W1:
Check fuses.
