2.4.2 Overview
Cs contouring control is a function for exercising position control by
handling the spindle as a CNC controlled axis with an MZi sensor,
BZi sensor, CZi sensor, or α position coder S.
This function enables positioning and interpolation with another servo
axis. This means that linear interpolation, circular interpolation, and so
forth can be specified between the spindle and a servo axis.
NOTE
To use this function, the CNC software option is
required.
