Note1. When the unit setting parameter value of the A1SD75 positioning module is changed from "3" (pulse) to "0" (mm), the
unit is 0.1 m for the input value. To set the unit to 1 m, add this program to multiple the feed value by 10.
2. The home position address loaded from flash ROM of normal positioning module can be obtained.
For updating the home position address by the home position setting,
refer to (2)(f)Data set type home position return in this Section.
