Hardware problem in the circuit for the management of high side driver. The
driver is turned ON but the output voltage does not increase.
Troubleshooting:
Verify that the coil is connected correctly between terminals PEB (pin A27) and
NEB (pin A28). The output of Smart driver is in fact evaluated checking the
voltage feedback of low side driver.
Verify that the parameter POSITIVE EB is set in accordance with the actual coil
positive supply (see paragraph 8.2.7). The software makes a proper diagnosis
depending on the parameter; a wrong setting could generate a false fault.
In case no failures/problems have been found, the problem is in the controller,
which has to be replaced.
SPEED FB. ERROR (MDI/LED code = 81)
Cause
This alarm occurs if the absolute position sensor is used also for speed
estimation. If signaled, it means that the controller measured that the engine was
moving too quick.
Troubleshooting
Check that the sensor used is compatible with the software release.
Check the sensor mechanical installation and if it works properly.
Also the electromagnetic noise on the sensor can be a cause for the alarm.
If no problem is found on the motor or on the speed sensor, the problem is inside
the controller, it is necessary to replace the logic board.
STALL ROTOR (MDI/LED code = 11)
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.
STBY I HIGH (MDI/LED code = 53)
Cause
In standby, the sensor detects a current value different from zero.
Troubleshooting
The current sensor or the current feedback circuit is damaged. Replace the
controller.
STEER SENSOR KO (MDI/LED code = 95)
Cause:
The voltage read by the microcontroller at the steering-sensor input is not within
the STEER RIGHT VOLT ÷ STEER LEFT VOLT range, programmed through the
STEER ACQUIRING function (see paragraph 9.3).
Troubleshooting:
Acquire the maximum and minimum values coming from the steering
potentiometer through the STEER ACQUIRING function. If the alarm is still
