ACQUIRING
A.S.
Cause:
Controller is acquiring data from the absolute feedback sensor.
Troubleshooting:
The alarm ends when the acquisition is done.
175
SPEED FB.
ERROR
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.
177
COIL SHOR.
EB.
Cause
This alarm occurs when an overload of the EB driver occurs
Troubleshooting
- Check the connections between the controller outputs and the loads.
- Collect information about characteristics of the coil connected to the
driver and ask for assistance to a Zapi technician in order to verify that the
maximum current that can be supplied by the hardware is not exceeded.
- In case no failures/problems have been found, the problem is in the
controller, which has to be replaced
178
MOTOR TEMP.
STOP
Cause:
The temperature sensor has overtaken the STOP MOTOR TEMP. threshold
(if analog).
Troubleshooting:
- Check the temperature read by the thermal sensor inside the motor
through the MOTOR TEMPERATURE reading in the TESTER function.
- Check the sensor ohmic value and the sensor wiring.
- If the sensor is OK, improve the cooling of the motor.
- If the warning is present when the motor is cool, replace the controller.
179
STEER
SENSOR KO
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
Troubleshooting:
- Acquire the maximum and minimum values coming from the steering
potentiometer through the STEER ACQUIRING function. If the alarm is
still present, check the mechanical calibration and the functionality of the
potentiometer.
- If the problem is not solved, replace the logic board
