(1)When executing weld line coordinate shift operation, start the JOB
with one step before ARCON instruction.
(2)When teaching the JOB for welding coordinate shift operation, set
the ARCON instruction in the JOB in which the weld line coordinate
shift operation is to be performed. (Don't set ARCON instruction in the
JOB which is target for CALL instruction without setting any weld start
teaching point.)
To use ARCON instruction without weld start point in the CALL
destination JOB, disable the weld line coordinated shift function in the
weld start condition file.
If the alarm occurs again, save the CMOS.BIN in maintenance mode,
and then contact your Yaskawa representative about occurrence
