Mitsubishi Electronics QD75D Pr.44 OPR direction, To 2000000000 ⋅ 10-2mm/min, Pr.1 Setting value

5 DATA USED FOR POSITIONING CONTROL

MELSEC-Q

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 " direction" is set as shown below.

Pr.44

OPR

Address decrement direction

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

	Set "1" for	Pr.44 .
