Adjustment Of Current Output - YASKAWA YWE-EH500-6N0 Instruction Manual

HW0480311
13.7 Adjustment of Current Output Characteristics
Parameter
No.
Welding current output characteristic 1
(150 A or less: default setting)
Changes the wire feeding amount so
P62
that the real welding current value corre-
sponds to the welding current com-
mand.
Welding current output characteristic 2
(250 A or more: default setting)
Changes the wire feeding amount so
P63
that the real welding current value corre-
sponds to the welding current com-
mand.
The welding current output can be adjusted by setting parameters P62 and P63. The change
in the welding current output includes checking the welding current command against the
welding current that is fed back.
For welding current output characteristics, use the welding current calibration function than
setting the value of parameters P62 and P63.

Guideline of Adjustment
- When real welding current value is
higher than the welding current com-
mand: Decrease the value.
- When real welding current value is lower
than the welding current command:
Increase the value.
- When real welding current value is
higher than the welding current com-
mand: Decrease the value.
- When real welding current value is lower
than the welding current command:
Increase the value.
