2.2 Check frequency converter (FC) (if applicable)
Check whether the LED is blinking (not when you are
switching on/off the controller) (depending on the type
of FC you need to take off the cover) or if the error
code 33”WARN FU” appears in the display.
If this is the case, proceed to point 2.2.1, otherwise to
point 2.3
2.2.1 Fault remedy on FC
When the controller is switched off (min for 20 sec),
and switched on again, a failure reset takes place.
Whether the fault does not appear again is uncertain
as the cause can could be on the motor, its wiring or on the brake
Check motor (e.g. corrosion on terminals, water leaks, short circuit on motor housing) as
well as the brake for proper function and its wiring for damages.
If the FC fault is caused by overheating, the FC needs to cool down completely (this might
take sometimes several hours) ! Then the FC will be started up again in a state where he can
act again properly.
If this has been checked and everything is in order but no result has been achieved,
change the FC.
2.3 Check the travel recognition PCB
Switch off main switch, execute the work mentioned, switch on the main switch again
Unplug the 2 connectors
Check whether the fault is still present
If fault still present, plug in the
connectors again and proceed to point 3
If not, exchange the travel recognition PCB
