 Tip!
When the fault messages are retrieved via the system bus (CAN) they are
displayed as a number (see column fault number ˘number" in the following
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 TRIP (axis
module, fix 100 %)
Current overload of the axis
module, e.g. by:
l frequent and too long
acceleration processes
l continuous overload with
I
motor
> 1.05 x I
Nx
Check drive dimensioning.
0016 OC6 I
2
x t overload TRIP (motor, C0120) Current overload of the motor,
e.g. due to:
l frequent or too long
acceleration processes
l impermissible continuous
current
l Check drive dimensioning.
l Check setting of C0120.
x017 OC7 I x t overload warning (axis
module, C0123)
Current overload of the axis
module > C0123 (e.g. due to
frequent or too long acceleration
phases)
l Check drive dimensioning.
l Check setting of C0123.
x018 OC8 I
2
x t overload warning
(motor, C0127)
Current overload of the motor
> C0127 (e.g. due to frequent or
too long acceleration phases)
l Check drive dimensioning.
l Check setting of C0127.
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 DC bus DC−bus voltage is lower than
specified under C0174.
l Check mains voltage.
l Check power supply module.
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.
x041 AP1 Internal fault Contact Lenze.
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.
Wrong mounting position Change mounting position.
x: 0 = TRIP, 1 = Message, 2 = Warning, 3 = FAIL−QSP
