Fehlerbeseitigung / Fault clearance
If the safety functions recognize a fault, the controller changes to the fault state.
In this case the driver block and the safety relay are deactivated first.
A fault state is indicated by flashing codes of the two LEDs on the controller:
First the red LED flashes rapidly, then it lights up continuously for approx. 20 seconds. During these 20 seconds
the green LED flashes in accordance with the fault code x times. The cycle repeats until the user resets the fault.
Example: Green LED flashes 4 times, i.e. Fault code 4. This corresponds to a defective oscillator.

Green LED
The following system states have been defined for the fault recognition:
Fault
code
Name Description Fault elimination
0 System OK No fault
1 Unknown fault Unknown cause of fault
X
Switch mains voltage off/on.
X
Carry out a reset as described in
Chapter 16.2 .
X
Replace the controller if neces-
sary.
2 Self-test – several faults The self-test has recognised several faults
4 Self-test – oscillator fault The self-test has recognised a defective
oscillator
X
Replace the controller.
5 Self-test – relay defective The self-test has recognised a defective
relay

ment defective
The current measurement does not func-
tion properly
X
Switch mains voltage off/on.

Carry out a reset as described in
Chapter 16.2 .
X
Replace the motor and/or con-
troller if necessary.
8 Self-test – driver fault recog-
nition defective
The power driver no longer outputs a fault
message
9 Hardware – encoder fault The encoder is not connected correctly or
is defective
X
Check the encoder connection.
X

10 Hardware – voltage impos-
sible
The supply voltage lies outside the per-
missible range

Replace the controller.
12 Memory – ROM defective The programme memory has been
changed or is defective
13 Memory – EEPROM defec-
tive
The data memory is defective
