M/S PAR CHK MISM (MDI/LED code = 97)
Cause
:
At start-up there is a mismatch in the parameter checksum between the
master and the supervisor microcontrollers.
Troubleshooting
:
Restore and save again the parameters list.
MOT.PHASE SH. XX (MDI/LED code = 47)
Cause
Short circuit between two motor phases. The hexadecimal value “XX”
identifies the shorted phases:
36: U – V short circuit
37: U – W short circuit
38: V – W short circuit
Troubleshooting
- Verify the motor phases connection on the motor side.
- Verify the motor phases connection on the inverter side.
- Check the motor power cables.
- Replace the controller.
- If the alarm does not disappear, the problem is in the motor. Replace it.
MOTOR TEMP. STOP (MDI/LED code = 65)
Cause:
The temperature sensor has overtaken the threshold defined by STOP
MOTOR TEMP. (if analog, see paragraph 8.2.3).
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.
MOTOR TEMPERAT. (MDI/LED code = 65)
Cause:
This warning occurs when the temperature sensor is open (if digital) or if it
has overtaken the MAX. MOTOR TEMP. threshold (if analog) (see paragraph
8.2.3).
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.
NO CAN MSG. XX (MDI/LED code = 67)
Cause
CANbus communication does not work properly. The hexadecimal value “XX”
identifies the faulty node.
