Probable Cause and Consequent Action
The CAN-BUS line diagnosis is present. The alarm appears if the inverter does not
receive any message from the CAN-BUS line. First, check the wiring. If this is cor-
rect, the problem is with the motherboard, which needs to be replaced.
The temperature sensor range of the AC-0 inverter is always checked and a warning
message appears in the event of a fault.
If this alarm occurs, wait and check the connection of the sensors.
The AC-0 controller signals the start. Usually appears when the key is ON.
The μP system controls the application of the electromechanical brake. The alarm
appears if the output status of the drive does not match the signal from the μP sys-
tem. Possible cause:
a. The electromechanical brake of the traction unit is not connected. Check the wir-
ing connection. Check the integrity of the cables.
b. Electromagnetic brake damaged. Check the ohmic coil of the electromagnetic
brake.
c. defective mechanism.
