Hardware Faults - Siemens SIMOREG DC Master 6RA7028-6DS22 Operating Instructions Manual

Faults / Alarms
Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Fault value:
1 Speed controller actual value selection in P083 is still set to 0
2 Rated motor armature current in P100 is still set to 0.0
Rated motor field current in P102 is still set to 0.00 (fault message only when P082 ≠ 0)
3
F058 Parameter settings are not consistent
(active in operating states of ≤ o6)
Inconsistent values have been set in mutually dependent parameters.
Fault value:
2 The parameters for speed-dependent current limitation are not set correctly (the following applies: P105>P107 (I1>I2) and
P104 < P106 (n1<n2))
3 The field characteristic is not uniform
4 The first threshold for P gain adaptation of the speed controller set in parameter P556 is higher than the second threshold
setting in parameter P559
5 P557 is set to greater than P560
6 P558 is set to greater than P561
7 If P083=1 (analog tachometer), then P746 may not equal 0 (main actual value is not connected)
8 If P083=2 (pulse encoder), then P140 may not equal x0 (no pulse encoder installed)
9 If P083=3 (EMF control) then P082 may not equal x1x (field weakening operation)
10 P090 (stabilization time for supply voltage) >P086 (time for automatic restart)
11 P090 (stabilization time for supply voltage) >P089 (waiting time in state o4 or o5)
12 P445=1 is set (switch-on, shutdown and crawl act as a pushbutton) although no binector is parameterized as a shudown
button (P444=0)
F059 Time has elapsed for temporary enabling of technology option S00
(active in all operating statuses)
The temporary enabling of technology option S00 for 500 operating hours no longer applies. The functions are now no longer
available, but the parameter settings have been retained.
If you wish to continue using technology option S00, please contact to your nearest Siemens Regional Office for a PIN number
for permanent enabling of technology option S00.
You will need to know the serial number of your SIMOREG DC Master. For further details, please refer to the description of
parameters U977 and n978 in Chapter 11 of the Parameter List.

10.1.2.11 Hardware faults

F061 Fault message from thyristor check function
(active in operating state o3)
This fault message can be activated only if the thyristor check is activated via parameter P830.
If "Thyristor defective" or "Thyristor unable to block" is signalled, then the relevant thyristor module must be replaced.
Possible causes for irreparable damage to thyristors:
•
Interruption in snubber circuit
•
Current controller and precontrol are not optimized (excessive current peaks)
•
Inadequate cooling (e.g. fan is not operating, ambient temperature is too high, fan is rotating in wrong direction (incorrect
phase sequence), inadequate air supply, heatsink is very dirty)
•
Excessive voltage peaks in incoming supply system
•
External short circuit or fault to ground (check armature circuit)
If "Thyristor unable to block" is signalled, the cause can generally be attributed to a firing circuit fault, rather than to a defective
thyristor.
Possible causes:
•
Firing pulse cable to relevant thyristor is interrupted
•
Ribbon cable X101 or X102 is incorrectly inserted or interrupted
•
Defective electronics or gating board
•
Internal interruption in gating cable in thyristor module
The designations of the firing cables and associated thyristors can be found in Section 6.4 (power connections).
