Value set with peripheral device
0 : Positive direction (address
increment direction)
1 : Negative direction (address
decrement direction)
The setting value range differs depending on the " Pr.1
Unit setting".
Here, the value within the [Table 1] range is set.
The setting value range differs depending on the " Pr.1

Here, the value within the [Table 2] range is set.
Pr.46 Zero point return direction
Set the direction to start movement when starting machine zero point return.
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 zero point is set near the lower limit or the upper limit, so " Pr.46
Zero point return direction" is set as shown below.
