Remedy Cause Description Fault message Remedy Cause Description
Display No.
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).
x062 CE1 Communication error on the
process data input object
CAN1_IN CAN1_IN object receives faulty
data or communication is
interrupted. l Check wiring at X4.
l Check sender.
l Increase monitoring time
under C0357/1, if necessary.
l Switch off monitoring
(C0591 = 3).
x063 CE2 Communication error on the
process data input object
CAN2_IN CAN2_IN object receives faulty
data or communication is
interrupted. l Check wiring at X4.
l Check sender.
l Increase monitoring time
under C0357/2, if necessary.
l Switch off monitoring
(C0592 = 3).
x064 CE3 Communication error on the
process data input object
CAN3_IN CAN3_IN object receives faulty
data or communication is
interrupted. l Check wiring at X4.
l Check sender.
l Increase monitoring time
under C0357/3, if necessary.
l Switch off monitoring
(C0593 = 3).
