Faults and Alarms
Number / Fault Cause
F107 A fault has occurred during the test pulse
measurement
MLd = 0
F108 During the DC measurement, the
measurement results for the individual phases
Mld Unsym differ significantly. The fault value indicates
which quantity(ies) is(are) concerned and in
which phase the greatest deviation occurred.
F109 The rotor resistance determined during DC
measurement deviates too significantly from
Mld R(L) the value which was calculated by the
automatic parameterization from the rated slip.

Read out fault value from r949. The figures of
the grey shaded areas indicate which fault has
occurred.
O O X X xx = 01: Both current actual values
xx = 02: Motor-converter cable
xx = 03: Motor converter phase V
xx = 04: Motor-converter phase W
xx = 05: Current actual value I1
xx = 06: Current actual value I3
xx = 07: Valve U+ does not trigger
xx = 08: Valve U- does not trigger
xx = 09: Valve V+ does not trigger
xx = 10: Valve V- does not trigger
xx = 11: Valve W+ does not trigger
xx = 12: Valve W- does not trigger
xx = 13: Sign I1 incorrect
xx = 14: Sign I3 incorrect
xx = 15: Sign I1 and I3 incorrect
xx = 16: Sign I1 confused with I3
xx = 17: I1 confused with I3 and
The digit of the xth digit indicates where the
fault has occurred.
X O O O x = 0 = Single converter
x = 1 = Inverter 1
x = 2 = Inverter 2
x = 3 = Inverters 1 and 2
Check that all 3 motor feeder cables and the
motor windings do not have any interruption.
Check the connection between the current
converter and the electronics and check the
current converter itself. Check the correct input
of the rating plate data for the motor data set
valid during the measurement.
Read out fault value from r949. The digit of the
xth position indicates;
O O O X Transverse voltage too high
x = 1 = phase R
x = 2 = phase S
x = 3 = phase T
O O X O Dev. stator resistance
(1, 2, 3 as above)
X O O O Dev. dead-time compensation
(1, 2, 3 as above)
X O O O O Dev. valve voltage
(1, 2, 3 as above)
The motor, power section or actual-value
sensing are significantly non-symmetrical.
- Incorrect input of rated speed or rated
frequency
- Pole pair number incorrect
