Overcurrent At least one of the power unit’s
three phase currents has overwrit

ten the value of 1,3 x I
max
(= 1,3 x
P113)
Inhibit pulses im-
mediately
Check the current control-
ler’s setting
0203
hex
Error current An error current was determined in
the power unit that exceeded a
specific amount. (For more de
-
tailed information, refer to the
power unit description.)
Inhibit pulses im-
mediately
Check the mains connec-
tion and the intermediate
circuit connection for a
ground fault
0204
hex
Disturbance in auxiliary
voltage supply
There is no power supply for tran-
sistor control in the power unit.
Inhibit pulses im-
mediately
Check control of the safety
relay
0205
hex
Overtemperature of
power unit
The temperature of the power unit
has risen above 85° C.
Inhibit pulses im-
mediately
The disturbance cannot be
acknowledged until the
power unit temperature
shown in P118 has fallen
below 85° C.

CE
monitoring of one or more
power transistors has tripped due,
for example, to a short circuit or
ground fault or because of defects
in the transistor.
Inhibit pulses im-
mediately
Check the motor cables
for a short circuit or
ground fault.
Allow the power unit to
cool down.
If the disturbance keeps
occurring, replace the
power unit.
020E
hex
Power unit ID unknown The control unit does not know the
read identifier
Inhibit pulses im-
mediately
Read off the power unit
version from the rating
plate and compare it with
the list in P117. The error
cannot be acknowledged.
020F
hex
Wrong power unit type The stored power unit type does
not match the one the system
read, e.g. because no data set has
been stored yet or you plugged
the control unit into another power
unit.
Inhibit pulses im-
mediately
Check the parameteriza-
tion and, if necessary,
change it. Save the data
set and acknowledge the
error.
0210
hex
Disturbance in power
unit
The ready for use signal from the
power unit is missing even though
there are no other power unit dis
-
turbance messages.
Inhibit pulses im-
mediately
Refer to the power units
operating instructions.

Short circuit tempera-
ture sensor
The power unit temperature is
below the temperature threshold
of -40°C. Normally, this distur
-
bance occurs if there is a short cir-
cuit in the temperature detection
during operation.

defective, the disturbance
cannot be eliminated.
