(2) Precautions during operation
(a) Another OPR after the completion of OPR
If another OPR is attempted after the completion of OPR, the error "OPR complete signal ON at start" (error
code: 84) occurs.
(b) Positions of the near-point dog OFF and Zero signal
If the position where the near-point dog turns off is close to Zero signal, the Zero signal may be misread,
resulting in deviation of OP by one servomotor rotation. Adjust the position where the near-point dog turns off
so that it becomes closer to the center of Zero signals.
(c) OPR start from the near-point dog ON position
If an OPR start is attempted from the near-point dog ON position, the error "Near-point dog signal ON at start"
(error code: 74) occurs.
Return the workpiece to a position away from the near-point dog using JOG operation, then execute OPR.
(d) Another OPR after the reset of the CPU module
If the CPU module was reset after OPR control was completed and the near-point dog turned off, another OPR
can be started; however, the operation is executed at " OPR speed" to the position of the upper limit
switch (FLS) or the lower limit switch (RLS) since there is no near-point dog placed in the OPR direction.
(e) Outside the stroke limit range
If the workpiece moved outside the stroke limit range, the error "Outside the stroke limit range" (error code:
100) occurs; although, the operation continues. In this case, the OPR is completed normally if the near-point
dog is placed on the OPR direction.
