Note!
If you use GDC or a fieldbus module to retrieve the fault (C0168/x), the error
message will be represented by an error number.

CCr x071 System fault Processor is overloaded or there is a
fault in the program processing Reduce processor load. Remove function
blocks that are not needed from the
processing table
Strong interference on control cables Shield control cables
Ground or earth loops in the wiring Check wiring
CE0 x061 Communication
error Fault during transmission of control
commands via automation interface X1 Plug in automation module firmly, bolt
down, if necessary
CE1 x062 Communication
error at the process
data input object
CAN−IN1 CAN−IN1 object receives faulty data, or
communication is interrupted l Check cable at X4
l Check sender
l Increase monitoring time under
C0357/1 if necessary
CE2 x063 Communication
error at the process
data input object
CAN−IN2 CAN−IN2 object receives faulty data, or
communication is interrupted l Check cable at X4
l Check sender
l Increase monitoring time under
C0357/2 if necessary
CE3 x064 Communication
error at the process
data input object
CAN−IN3 CAN−IN3 object receives faulty data, or
communication is interrupted l Check cable at X4
l Check sender
l Increase monitoring time under
C0357/3 if necessary
CE4 x065 BUS−OFF state Controller has received too many
incorrect telegrams via system bus X4,
and has disconnected from the bus l Check wiring
l Check bus termination (if any)
l Check shield contact of the cables
l Check PE connection
l Check bus load
l Reduce baud rate (observe cable
length)
EEr x091 External fault
(TRIP−Set) A digital input assigned with TRIP−set
function has been activated (in the most
basic configurations the input X5/E4 is
LOW−active and linked with the TRIP−set
function) l Check external encoder
l Check signal at the digital input
X5/E4:
– Either connect HIGH level or
– Change polarity in C0114 to
HIGH−active. CAUTION! When
changing to HIGH level, the
wire−break protection gets lost.
The two terminal strips at X5 are
reversed Check the position of the terminal
strips:
l If you look at the connection unit in
reading direction, the left terminal
strip X5 must be connected with the
input signals and the right terminal
strip X5 must be connected with the
output signals.
