Faults / Alarms
Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
F052 Optimization run aborted as a result of external cause
(active in operating states of – –, I, II)
This fault message is activated when the converter ceases operating in the RUN state (state I, II or --) during an optimization run
(and thus in response to every FAULT) or if the EMERGENCY STOP or SHUTDOWN command is applied. The optimization run
is aborted. Only those parameters which had been fully optimized prior to activation of the fault message are altered .
When the STANDSTILL command is applied, this fault message is not activated if the optimization run for field weakening is
interrupted after the 1st field weakening measuring point has been recorded or, in the case of the optimization run for friction and
moment of inertia compensation, after the measuring point at 10% maximum speed has been determined. In these cases, the run
may be interrupted by STANDSTILL so as to be able to complete the run in several stages (by repeated restarts) for a limited
travel path.
Fault value:
1 Run was aborted because converter is no longer
operating in RUN mode
(For example, this can occur when r047i002=2 in the
case of a motor with a very high field circuit time constant
→ For help, see P051 = 26 in chapter 7.5)
2 Run was aborted because EMERGENCY STOP
command was applied (speed controller setpoint =0)
3 Run was aborted because STANDSTILL command was
applied (ramp-function generator setpoint=0)
4 Operation has been aborted because P051 was changed
during the optimization run
5 Run was aborted because SWITCH-ON command was
not applied within 30 s of selection of optimization run
6 Operation has been aborted because the OPERATING
ENABLE command was not entered within 1 minute of
selection of the optimization run.
7 Operation has been aborted because converter was not
in operating state < o7.2 15 s after selection of the
optimization run with P051 = 25, 26, 27 or 28 (input of
OFF1 command may have been forgotten)

10.1.2.10 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)

Description
Further information (r047.002 to r047.016)
r047 Index 002 to 016:
i002=1 Fault has occurred during optimization run for current
controller and precontrol for armature and field
(selected by means of P051=25)
i002=2 Fault has occurred during optimization run for speed
controller (selected through setting P051=26)
i002=3 Fault has occurred during optimization run for field
weakening (selected through setting P051=27)
i002=5 Fault has occurred in optimization run for friction and
moment of inertia compensation (selected through
setting P051=28)
