DisplayNo.
2020 OU Overvoltage in the DC bus Braking energy is too high.
(DC−bus voltage is higher than set
in C0173.)
l Use a braking unit or
regenerative module.
l Check dimensioning of the
brake resistor.
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.
Wrong mounting position Change mounting position.
x053 OH3 Motor temperature
> +150 °C threshold
(temperature detection via
resolver or incremental value
encoder)
Motor is thermally overloaded
due to:
l Impermissible continuous
current
l Frequent or too long
acceleration processes
l Check drive dimensioning.
l Switch off monitoring
(C0583 = 3).
No PTC/temperature contact
connected.
Correct wiring.
x054 OH4 Heatsink temperature > C0122
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.
l Switch off monitoring
(C0582 = 3).
Heatsink is very dirty. Clean heatsink
Wrong mounting position Change mounting position.
The value specified under C0122
is set too low.
Enter a higher value under C0122.
x057 OH7 Motor temperature > C0121
(temperature detection via
resolver or incremental value
encoder)
Motor is thermally overloaded
due to:
l Impermissible continuous
current
l Frequent or too long
acceleration processes
l Check drive dimensioning.
l Switch off monitoring
(C0584 = 3).
No PTC/temperature contact
connected.
Correct wiring.
The value specified under C0121
is set too low.
Enter a higher value in C0121.
x058 OH8 Motor temperature via inputs T1
and T2 is too high.
Motor is thermally overloaded
due to:
l Impermissible continuous
current
l Frequent or too long
acceleration processes
l Check drive dimensioning.
l Switch off monitoring
(C0585 = 3).
Terminals T1 and T2 are not
connected
Connect PTC/temperature
contact.
x061 CE0 Automation interface (AIF)
communication error
Faulty transfer of control
commands via AIF.
l Plug in the communication
module/keypad XT firmly,
screw down, if necessary.
l Switch off monitoring
(C0126 = 3).
