Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
32)
EPS RELAY OPEN
Cause:
The controller receives from EPS information about the safety contacts being
open.
Troubleshooting:
Verify the EPS functionality.
33)
VACC NOT OK
Cause:
At key-on and immediately after that, the travel demands have been turned off.
This alarm occurs if the ACCELERATOR reading (in TESTER function) is more
than 1 V above the minimum value acquired during the PROGRAM VACC
procedure.
Troubleshooting:
-
Check the wirings.
-
Check the mechanical calibration and the functionality of the accelerator
potentiometer.
-
Acquire the maximum and minimum potentiometer value through the
PROGRAM VACC function.
-
If the problem is not solved, replace the logic board.
34)
STALL ROTOR
Cause:
The traction rotor is stuck or the encoder signal is not correctly received by the
controller.
Troubleshooting:
-
Check the encoder condition.
-
Check the wiring.
-
Through the TESTER function, check if the sign of FREQUENCY and
ENCODER are the same and if they are different from zero during a traction
request.
-
If the problem is not solved, replace the logic board.
35)
PARAM RESTORE
Cause:
The controller has restored the default settings. If a CLEAR EEPROM has been
made before the last key re-cycle, this warning informs you that EEPROM was
correctly cleared.
Troubleshooting:
-
A travel demand or a pump request cancel the alarm.
