REMARK
Positioning parameter settings work in common for all controls using the Simple
Motion module. When carrying out other controls ("major positioning control",
"high-level positioning control", and "OPR control"), set the respective setting items
as well.
Parameters are set for each axis.
Refer to Chapter 5 "Data Used for Positioning Control" for the setting details.
