(Parameter No.1320 or 1326 NOTE)
501 OVER TRAVEL : --n Exceeded the n--th axis (axis 1--8) -- side stored stroke check I.
(Parameter No.1321 or 1327 NOTE)
502 OVER TRAVEL : +n Exceeded the n --th axis (axis 1--8) + side stored stroke check II.
(Parameter No.1322 )
503 OVER TRAVEL : --n Exceeded the n--th axis (axis 1--8) -- side stored stroke check II.
(Parameter No.1323)
504 OVER TRAVEL : +n Exceeded the n --th axis (axis 1--8) + side stored stroke check III.
(Parameter No.1324 )
505 OVER TRAVEL : --n Exceeded the n--th axis (axis 1--8) -- side stored stroke check III.
(Parameter No.1325 )
506 OVER TRAVEL : +n Exceeded the n --th axis (axis 1--8) + side hardware OT.
507 OVER TRAVEL : --n Exceeded the n--th axis (axis 1--8) -- side hardware OT.
508 INTERFERENCE: +n
(T series (two --path control))
A tool moving in the positive direction along the n axis has fouled anoth-
er tool post.
509 INTERFERENCE: --n
(T series (two --path control))
A tool moving in the negative direction along the n axis has fouledanoth-
er tool post.
510 OVER TRAVEL: +n Alarm for stroke check prior to movement. The end point specified in a
block falls within the forbidden area defined with the stroke check in the
positive direction along the N axis. Correct the program.
511 OVER TRAVEL: --n Alarm for stroke check prior to movement. The end point specified in a
block falls within the forbidden area defined with the stroke check in the
negative direction along the N axis. Correct the program.
NOTE
Parameters 1326 and 1327 are effective when EXLM(stroke check switch signal) is on.
