These inverter error messages are related to output short-circuit problems.
1
NO
Replace the inv erter
YES
Is the inv erter output short-

Is there a short-circuit on the
motor cable terminals?
Replace the belt motor

Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) Disconnect the motor cable from the inverter and place the tester probes between its U-V, U-
W and V-W terminals. The measured resistance should be very high, in the order of MOhm. It
is difficult to make a stable measurement of resistance, however a phase can be considered
short circuited or defective when the measured resistance is in the order of a few tens of
Ohms.
(2) Place the tester probes between the blue – black, blue – brown and black – brown conductors
of the motor cable. The measured resistance should be 3.3 Ohm.
