8 OPR CONTROL

8.2.3 OPR method (1): Near-point dog method

The following shows an operation outline of the "near-point dog method" OPR method.

Operation chart

1)

The machine OPR is started.
(The machine begins the acceleration designated in " Pr.51 OPR acceleration time selection", in the direction
designated in " Pr.44 OPR direction". It then moves at the " Pr.46 OPR speed" when the acceleration is completed.)

2)

The machine begins decelerating when the near-point dog ON is detected.

3)

The machine decelerates to the " Pr.47 Creep speed", and subsequently moves at that speed.
(At this time, the near-point dog must be ON. The workpiece will continue decelerating and stop if the near-point dog is
OFF.)

4)

After the near-point dog turns OFF, the pulse output from the QD75 will stop at the first zero signal, outputting a
"deviation counter clear signal" to the drive unit.
(The "deviation counter clear signal output time" is set in Pr.55 .)

5)

After a "deviation counter clear signal" is output to the drive unit, the OPR complete flag ( Md.31 Status: b4) turns from
OFF to ON and the OPR request flag ( Md.31 Status: b3) turns from ON to OFF.

Adjust so the near-point dog OFF
position is as close as possible to
the center of the zero signal HIGH level.
If the near-point dog OFF position
overlaps with the zero signal, the
machine OPR stop position may
deviate by one servomotor rotation.
