Fault
Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
27
Load torque is too high (nset=0% nmax results in |EMF| >100% setpoint EMF) (EMF monitoring at
≥
(P101 – P100 * P110)
does not start for 1 s after application of speed setpoint of nset=0)
Possible cause:
•
An excessively high load torque (in a positive or negative direction, e.g. suspended load) causes the drive to rotate (the
speed controller parameters are parameterized according to the factory setting during this run)
•
One of the armature current or torque limits is parameterized too low (the motor field may not be reaching full field
strength fast enough with the result that the initial motor torque is too low)
•
Maximum speed setting is incorrect
•
Pulse encoder parameters are incorrect (P140 to P143)
•
Parameters for tachometer adjustment are not correct (P741)
•
Setpoint EMF settings are incorrect (P101, P100, P110)
28
A steady-state actual speed corresponding to 0% of maximum speed cannot be reached within 0 s in speed-controlled
operation (the speed setpoint/actual value difference averaged over 90 firing cycles must be <1.0% nmax for a total of 4s)
Possible cause: As for fault value 26

The calculated armature circuit inductance is greater than 327.67 mH, therefore P111 = 327,67 mH has been set. All other
parameters (the current controller parameters P155 and P156 too) have been set correctly despite that. (For the real
armature circuit inductance in mH, see r047.i010).
Possible cause:
•
e.g. field supply from the armature terminals
30
The calculated armature circuit inductance is greater than 327.67 mH and the calculated armature circuit resistance is
greater than 32.767
Ω
, therefore P111 = 327,67 mH and P110 = 32,767
Ω
has been set. All other parameters have also
been set. However, the values of the current controller parameters P155 and P156 might differ from the optimum setting.
Possible cause:
•
e.g. field supply from the armature terminals
31
The calculated armature circuit resistance is greater than 32.767
Ω
, therefore P110 = 32,767
Ω
has been set. All other
parameters have also been set. Possibly the calculated P111 and therefore also the current controller parameters P155
and P156 have been distorted by the limitation in P110 .
Possible cause:
•
e.g. field supply from the armature terminals
r047 Index 002:
1
Fault has occurred during optimization run for current controller and precontrol for armature and field (selected by means of
P051=25)
2
Fault has occurred during optimization run for speed controller (selected through setting P051=26)
3
Fault has occurred during optimization run for field weakening (selected through setting P051=27)
4
Fault has occurred during internal offset adjustments (selected through P051=22)
5
Fault has occurred in optimization run for friction and moment of inertia compensation (selected through setting P051=28)
F051
No optimization run when permanent memory is disabled
[V2.1 and later]
(active in all operating states)
If P051.001 is set to 0 (write access to permanent memory disabled), it is not possible to execute an optimization run.
