32*
Current sensor fault
The current sensor is abnormal.
(32* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check the wiring of the motor.
► Replace the motor.
► Replace the wire feed control unit.
33*
Overload fault
The power supplied to the motor
exceeds the preset value.
(33* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check whether wires are damaged.
► Check the wire guide path for dirt and clean
it if necessary to ensure uniform wire
guidance.
► Ensure that the nominal duty cycle is not
exceeded. Use the high-power version if
necessary.
► Check the wiring of the motor.
► Replace the wire feed control unit.
► Replace the motor.
34*
Bit jump error
The change to the current position in
the encoder data exceeds the bit
jump detection level.
(34* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check the wiring of the motor and encoder.
► Replace the motor and encoder cables.
► Replace the motor or encoder.
► Replace the wire feed control unit.
35*
Excessive rotation fault
The change to the current position in
the encoder data exceeds the bit
jump detection level.
(35* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check the wiring of the motor and encoder.
► Replace the motor and encoder cables.
► Replace the motor and encoder.
36*
Tracking fault
The motor cannot reach the
command position.
(36* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check whether wires are damaged.
► Check the wire guide path for dirt and clean
it if necessary to ensure uniform wire
guidance.
► Make sure that the primary power supply’s
voltage is not below the nominal value.
► Ensure that the ambient temperature does
not fall below 0°C.
► Check the wiring of the motor.
► Replace the motor.
37*
Motor connection fault
The motor does not rotate according
to the movement command.
(37* 1: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Ensure that the motor's connection lead is not
damaged and is connected correctly.
► If necessary, connect the connecting lead
correctly or replace it.
► If no damage to the motor performance can
be visually detected, feed the welding wire
and check whether the motor rotates evenly.
If the motor rotates unevenly or not at all,
replace the motor cable and, if necessary,
the motor.
► Contact the service team.
401
Wire Buffer KINETIC calibration
error
The value for the encoder current
falls below or exceeds the minimum
or maximum value determined during
calibration.
In the event of EMERGENCY OFF or
if welding wire is pulled out by force.
► Calibrate the Wire Buffer KINETIC and
save.
► If the fault occurs again after calibration,
check whether the wire feed path is clean
and the welding wire is being fed evenly.
411
Wire Buffer KINETIC not calibrated
The Wire Buffer KINETIC has not
been calibrated.
► Calibrate the Wire Buffer KINETIC and
save.
► Press the save button straight after
performing the calibration.
