12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.44] Home position return direction
Set the direction to start movement when starting machine home position return.
Normally, the home position is set near the lower limit or the upper limit, so "[Pr.44] Home position return direction" is set as
shown below.
[Pr.45] Home position address
Set the address used as the reference point for positioning control (ABS system).
(When the machine home position return is completed, the stop position address is changed to the address set in "[Pr.45]
Home position address". At the same time, the "[Pr.45] Home position address" is stored in "[Md.20] Current feed value" and
"[Md.21] Machine feed value".)
Setting value Details
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))

Upper limit
When the zero point is set at the lower
limit side, the home position return direction
is in the direction of arrow 1).
Set "1" for [Pr.44].
