5 DATA USED FOR POSITIONING CONTROL

Pr.44 OPR direction

Set the direction to start movement when starting machine OPR.

0: Positive direction (address increment direction)

Moves in the direction that the address increments. (Arrow 2))

1: Negative direction (address decrement direction)

Moves in the direction that the address decrements. (Arrow 1))

Normally, the OP is set near the lower limit or the upper limit, so "

When the zero point is set at the lower
limit side, the OPR direction is in the
direction of arrow 1).
Set "1" for .
