6.4.1. THE INVERTER DISPLAY SHOWS E01, E02, E03, E04 OR E05
These inverter error messages are related to output short-circuit problems.
1
NO
Replace the inverter
YES
Is the inverter output
short-circuited?
Is there a short-circuit on the
motor cable terminals?
Replace the belt motor
2
YES
Does the machine resume
correct operation after being
turned off for 1 minute?
YES
Probable interference. The
machine is OK
Replace the inverter
NO
NO
E02 E03 E04 E05E01
Change deck and belt
and/or lubricate
YES
Are the deck and the belt in
a good state and lubricated?
NO
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 terminals
U-V, U-W and V-W. The measured resistance should be very high, in the order of MOhms. It
is difficult to obtain a stable resistance measurement, 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) Disconnect the motor cable from the inverter and place the tester probes across the motor
cables connected to terminals U,V,W on the inverter. The measured phase-phase resistance
should be approximately 3.1 Ohms.
