(4) Relationship between this function and Cs contour control
When the Cs contour control function is provided, the Cs–axis contour control mode must be released be-
fore the spindle synchronization function is executed. If the spindle synchronization command is entered
in the Cs contour control mode, the system does not enter the spindle synchronization mode. (The syn-
chronization command is ignored and the system continues to be in the Cs contour control mode. The
system can enter the spindle synchronization mode only after the spindle mode is specified by SCNTRx.)
When the Cs contour control mode is specified in the spindle synchronization mode, the system enters
the Cs contour control mode.
(5) Configuration of the spindle synchronization system
(a) System in which the spindle and the spindle motor are connected by a belt or gear
