5 DATA USED FOR POSITIONING CONTROL
5.1.2 Setting items for positioning parameters
The setting items for the "positioning parameters" are shown below. The "positioning
parameters" are commonly set for each axis for all control using the AD75.
Refer to "SECTION 2" for details on each control, and section "5.2 List of parameters"
for details on each setting item.
