Zapi DUALACE2 NEW GENERATION User Manual

AFNZPxxx– DUALACE2 NEW GENERATION – User Manual Page 137/169
This alarm occurs when there is an overload of the EB driver (pin A28). As soon
as the overload condition disappears, the alarm will be removed automatically by
releasing and then enabling a travel demand.
Troubleshooting:
The typical root cause is in the wiring harness or in the load coil. So the very first
check to carry out concerns the connections between the controller outputs and
the loads.
Collect information about characteristics of the coils connected to the two drivers
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.
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 TEMPERAT. (MDI/LED code = 65)
Cause:
This warning occurs when the temperature sensor has overtaken the MAX.
MOTOR TEMP. threshold (if analog) (see paragraph 8.2.5).
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 TEMP. STOP. (MDI/LED code = 65)
Cause:
This warning occurs when the temperature sensor is open (if digital) or if it has
overtaken the TEMP. MOT. STOP threshold (if analog) (see paragraph 8.2.5).
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)
