The motor controller indicates a short-circuit
in the motor windings, cabling or internally in
the motor controller.
If the power is on, be very careful when
working on the machine.
Switch off the machine for at least 30 seconds to
ensure the motor controller has been completely
reset. Then try to start the machine again. If the
error returns, troubleshoot as follows:
1. Switch off the machine. Undo the contactor at X3 on the
Fig.
motor. Use an ohm meter to measure the resistance
38
towards the motor. Measure between 1-2, 1-3, and 2-3.
Resistance
W365H 4 ohm
W375H 4 ohm
W3105H 4 ohm
W3130H 2 ohm
W3180H 1,2 ohm
W3240H 0,8 ohm
W3300H 0,8 ohm
Correct resistance
2. Inspect the cabling from X312 on the motor controller to
Fig.
X3 on the motor. Use an ohm meter and measure the five
39
leads as follows:
X312: 1 2 3
X3: 1 2 3
Also measure the five leads to be sure there is no short-
circuit between any two leads.
Cabling OK
The motor controller output is defective.

12. Troubleshooting
One of the resistance
values is incorrect
The motor is probably
defective.
(X3:4 - 6, 8 not used)
Incorrect cabling
Inspect the cabling and
replace if necessary.
