Number / Fault Cause
F085 A fault has occurred during initialization of the
CB board.
Add. CB initialization
fault
F087 A fault has occurred during initialization of the
SLB board.
SIMOLINK initialization

F099 Recording of the friction characteristic was
interrupted or not done at all.
Friction characteristic
record
F109 The rotor resistance determined during
measurement of the direct current deviates too
Mld R(L) greatly.
F111 A fault has occurred during the Mot Id.
MId DSP r949=1 The current does not build up when
voltage pulses are applied
r949=2 (only for P115=4) The difference
between speed setpoint and actual value is
too large during measurement
r949=3 (only for P115=4) The magnetizing
current determined is too high.
r949=121 The stator resistance P121 is not
determined correctly
r949=124 The rotor time constant P124 is
parameterized with the value 0 ms
r949=347 The valve voltage drop P347 is not
determined correctly
F112 A fault has occurred during measurement of
the motor inductances or leakages.
Mid X(L)
F114 The converter has automatically stopped the
automatic measurement due to the time limit
MId OFF up to power-up having been exceeded or due
to an OFF command during the measurement,
and has reset the function selection in P115.

Counter-measure
Fault value r949:
1: Board code incorrect
2: TB/CB board not compatible
3: CB board not compatible
5: Error in configuration data
6: Initialization timeout
7: TB/CB board double
10: Channel error
Check the T300 / CB board for correct
contacting and check the CB initialization
parameters:
- P918.02 CB Bus Address,
- P711.02 to P721.02 CB Parameters 1 to 11
- Replace CU (-A10), or replace the unit
(Compact PLUS type)
- Replace SLB
Fault value r949 gives the cause (bit coded):
Bit Meaning
0 Pos. speed limit
1 Neg. speed limit
2 Releases missing:
direction of rotation, inverter, controller
3 Speed controller connecting
4 Interrupt through cancellation of the 16
record command
5 Illegal dataset changover
6 Time exceeded
7 Measuring error
- Repeat measurement
- Enter data manually
- Repeat measurement
- When r949=1: Check motor cables
- When r949=2: Avoid mechanical stressing of
the motor during the measurement; if the fault
occurs directly after the start of the motor
identification check the encoder and motor
cables.
- When r949=3: Check the motor rating plate
data stored (ratio Vrated / Irated does not
correspond with the measured inductance
- Repeat measurement
Re-start with P115 function selection = 2
"Motor identification at standstill".The ON
command must be given within 20 sec. after
the alarm message A078 = standstill
measurement has appeared.
Cancel the OFF command and re-start
measurement.
