- 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.
SMARTDRIVER KO
(MDI/LED code = 69)
Cause:
There is a hardware problem in the smart driver circuit (high-side driver on
pin
A2 ). The driver is set to be ON but the output voltage does not increase.
Troubleshooting:
- Verify that the EB coil is connected correctly between pin A2 and pin A4 .
- Verify that the parameter POSITIVE E.B.is set in accordance with the
actual configuration (see paragraph 8.2.5). The software, in fact,
depending on specific parameter value, makes a proper diagnosis; a
wrong configuration of this parameter could generate a false fault.
- In case no failures/problems have been found, the problem is in the
controller, which has to be replaced.
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 present, check the mechanical calibration and the functionality of the
potentiometer.
- If the problem is not solved, replace the logic board.
TH. PROTECTION
(MDI/LED code = 62)
Cause:
The temperature of the controller base plate is above 85 °C.
The maximum current is proportionally decreased with the temperature
excess from 85 °C up to 105 °C. At 105 °C the current is limited to 0 A.
