#6 (OFS) : A current conversion error has occured in the digital servo.
#5 (MCC) : A magnetic contactor contact in the servo amplifier has welded.
#4 (LDA) : The LED indicates that serial pulse coder C is defective
#3 (PMS) : A feedback pulse error has occured because the feedback cable is
defective.

Number Message Contents
500 OVER TRAVEL : +n Exceeded the n–th axis (axis 1 to 8) + side stored stroke limit I.
(Parameter No.1320 or 1326 NOTE)
501 OVER TRAVEL : –n Exceeded the n–th axis (axis 1 to 8) – side stored stroke limit I.
(Parameter No.1321 or 1327 NOTE)
502 OVER TRAVEL : +n Exceeded the n–th axis (axis 1 to 8) + side stored stroke limit II.
(Parameter No.1322 )
503 OVER TRAVEL : –n Exceeded the n–th axis (axis 1 to 8) – side stored stroke limit II.
(Parameter No.1323)
504 OVER TRAVEL : +n Exceeded the n–th axis (axis 1 to 8) – side stored stroke limit III.
(Parameter No.1324)
505 OVER TRAVEL : –n Exceeded the n–th axis (axis 1 to 8) – side stored stroke limit III.
(Parameter No.1325)
506 OVER TRAVEL : +n Exceeded the n–th axis (axis 1 to 8) + side hardware OT.
507 OVER TRAVEL : –n Exceeded the n–th axis (axis 1 to 8) – side hardware OT.
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.
514 INTERFERENCE : +n The rotation area interference check function found interference on the
plus side of the n axis.
515 INTERFERENCE : –n The rotation area interference check function found interference on the
minus side of the n axis.
NOTE
Parameters 1326 and 1327 are effective when EXLM (stroke limit switch signal) is on.
