4489 DEFECTIVE TAUGHT
POINT(CUTTING)
[Decimal Data]
Impossible to execute cutting motion.
Data stands for the alarm factor.
1:CW axis CUT pulse error
C,W axis position on cutting start is not
zero(0) pulse.
2:Cutting(edge) radius 0
Cutting (edge) radius is zero(0).
1:Set C,W axis position of cutting start
position zero(0).
2:Set the radius zero(0) or more.

occurred as follows. When operating play-
back panel and programming pendant,
though continuous rotation was com-
pleted, MRESET instruction was not exe
cuted but linear interpolation was
executed.
4:Instruction position of step has permitted
pulse over cursor for endless axis
exceeded 2,147,483,647 pulse.
1:In case this alarm occurs when operat
ing programing pendant, reset the alar
and execute the MRESET operation.
In case this alarm occurs when operat-
ing playback, set the MRESET instruc-
tion before executing the MOVL, MOVC
instruction
4:Check the teaching position again. Set
C,W axis position of cutting start posi-
tion zero(0).
