IPM overcurrent fault
The power supply module (IPM)
supplies the wire feed control unit
with impermissibly high current.
(10* 1: Wire Buffer KINETIC /
2: Push Feeder KINETIC /
3: Pull Feeder KINETIC)
► Check the wiring of the motor.
► Replace the motor.
► Replace the wire feed control unit.
117
PN overcurrent fault
The motor supply voltage (P-N)
exceeds the set value.
► Make sure that the voltage of the primary
power supply is within the specified range.
► Check the wiring of the motor.
► Replace the motor.
► Replace the wire feed control unit.
127
Abnormal drop in motor voltage
The motor supply voltage (P-N) falls
below the set value.
► Make sure that the voltage of the primary
power supply is within the specified range.
► Check the wiring of the motor.
► Replace the motor.
► Replace the wire feed control unit.
137
Power supply unit (P10V) fault
The power supply unit P10 (+10 V) is
not supplying power to the wire feed
control unit.
► Check the cable connection between the
constant voltage source and the wire feed
control unit.
► Replace the wire feed control unit.
147
Power supply unit (G15V) fault
The power supply unit G15 (+15 V)
is not supplying power to the wire
feed control unit.
► Check the cable connection between the
constant voltage source and the wire feed
control unit.
► Replace the wire feed control unit.
157
Abnormal drop in primary voltage
Primary voltage present falls below
the regular value.
► Make sure that the voltage of the primary
power supply is within the specified range.
► Check the cable connection between the
constant voltage source and the wire feed
control unit.
► Replace the wire feed control unit.
167
Phase failure of primary voltage
supply
One phase of the primary voltage
supply has failed.
► Check the wiring of the primary voltage
supply.
► Check the voltage of the primary voltage
supply.
► Replace the primary voltage supply.
► Replace the wire feed control unit.
177
Preload fault
A preload fault has occurred.
► Ensure that the wire feed control unit is
supplied with power (+24 V).
► Replace the wire feed control unit.
187
Power supply unit P15 (+15 V) fault The power supply unit P15 (+15 V) is
not supplying power to the wire feed
control unit.
► Check the cable connection between the
constant voltage source and the wire feed
control unit.
► Replace the wire feed control unit.
197
Power supply unit P24 (+24 V) fault The power supply unit P24 (+24 V) is
not supplying power to the wire feed
control unit.
► Check the cable connection between the
constant voltage source and the wire feed
control unit.
► Replace the wire feed control unit.
