7 Error display
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.
The following system states have been defined for the fault recognition:
Fault Name
code
0 System OK
1 Unknown fault
2 Self-test – several faults
4 Self-test – oscillator fault
5 Self-test – relay defective
6 Self-test – driver defective
7 Self-test – current measure-
ment defective
8 Self-test – driver fault recog-
nition defective
9 Hardware – encoder fault
10 Hardware – voltage impos-
sible
11 Memory – RAM defective
12 Memory – ROM defective
13 Memory – EEPROM defec-
tive
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.
