Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
1
the binector wired via parameter U103 Index.005 is in the state log."1"
2
the binector wired via parameter U103 Index.006 is in the state log."1"
3
the binector wired via parameter U103 Index.007 is in the state log."1"
4
the binector wired via parameter U103 Index.008 is in the state log."1"
9.1.2.10
Start-up faults
F055
No field characteristic recorded
(active in operating states of – –, I, II)
Possible fault causes
♦ The optimization run for field weakening (P051=27) has not yet been executed.
Fault value:
1
P170 = 1 ("torque control") selected, but "no valid field characteristic has been recorded" (P117=0) yet
2
P081 = 1 ("speed-dependent field weakening") selected, but "no valid field characteristic has been recorded" (P117=0) yet
(P117=0)
F056
Important parameter is not set
(active in operating states of ≤ o6)
This fault message is activated if certain parameters are still set to 0.
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
4
Rated DC current of external field device is still set to 0.00 in U838 (error message if P082 >= 21 only)
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
4
P557 is set to greater than P560
5
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)
13
If P067 > 1, then P075 must also be > 0
14
Parameter U673 > U674 (this setting is not permitted; see function diagram B152)
15
Parameter P169 = 1 and P170 = 1 (impermissible setting)
F059
Technology option S00 is disabled/will be disabled soon
(active in all operating statuses)
