Number Message Contents
500 OVER TRAVEL : +n Exceeded the n–th axis + side stored stroke limit I.
(Parameter No.1320 or 1326 Notes)
501 OVER TRAVEL : –n Exceeded the n–th axis – side stored stroke limit I.
(Parameter No.1321 or 1327 Notes)
502 OVER TRAVEL : +n Exceeded the n–th axis + side stored stroke limit II.
(Parameter No.1322 )
503 OVER TRAVEL : –n Exceeded the n–th axis – side stored stroke limit II.
(Parameter No.1323)
504 OVER TRAVEL : +n Exceeded the n–th axis + side stored stroke limit III.
(Parameter No.1324 )
505 OVER TRAVEL : –n Exceeded the n–th axis – side stored stroke limit III.
(Parameter No.1325 )
506 OVER TRAVEL : +n Exceeded the n–th axis + side hardware OT.
507 OVER TRAVEL : –n Exceeded the n–th axis – side hardware OT.
508 INTERFERENCE : +n When n–axis is moving in the positive direction, it interferes with the or-
der tool post (only with two–path control)
509 INTERFERENCE : –n When n–axis is moving in the negative direction, it interferes with the or-
der tool post (only with two–path control)
510 OVER TRAVEL : +n A stroke limit check, made before starting movement, found that the end
point of a block falls within the plus (+) side inhibited area along the n–
axis defined by a stroke limit. Correct the program.
511 OVER TRAVEL : –n A stroke limit check, made before starting movement, found that the end
point of a block falls within the minus (–) side inhibited area along the
N–axis defined by a stroke limit. Correct the program.
