Note!
In the case of a query via system bus (CAN), the fault messages are
represented as numbers (see first column of the table).
Fault message Description Cause Remedy
No. Display
−−− −−− No fault − −
0011 OC1 Short circuit of motor cable Short circuit l Search for cause of short
circuit.
l Check motor cable.
Excessive capacitive charging
current in the motor cable. Use motor cable which is shorter
or of lower capacitance.
0012 OC2 Motor cable earth fault One of the motor phases has
earth contact. l Search for cause of short
circuit.
l Check motor cable.
0015 OC5 I x t overload l Frequent and too long
acceleration with overcurrent
l Continuous overload with
I
motor
> 1.05 x I
rx.
Check drive dimensioning.
0016 OC6 I 2 xt overload l Frequent and too long
acceleration processes with
motor overcurrent.
l Permanent motor overload
with I

Check drive dimensioning.
1020 OU Overvoltage in DC bus Braking energy is too high.
(DC−bus voltage is higher than set
in C0173.) l Use braking unit or
regenerative module.
l Check dimensioning of the
brake resistance.
1030 LU Undervoltage in the DC bus DC bus voltage is lower than
specified in C0173. l Check mains voltage
l Check supply cable
x032 LP1 Motor phase failure A current−carrying motor phase
has failed. l Check motor.
l Check motor cable.
l Switch off monitoring
(C0597 = 3).
The current limit value is set too
low. l Set higher current limit value
via C0599.
0050 OH Heatsink temperature > +90 C Ambient temperature
T
u
> +40 C or > +50 C
l Allow module to cool and
ensure better ventilation.
l Check ambient temperature in
the control cabinet.
Heatsink is very dirty. Clean heatsink.
