(1) synchronization of the C–axis to the hob
axis (G81).
#1 CMS : The position manually set with a single rotation
signal is canceled (0)/not canceled (1) when a
synchronization cancel command is issued.

specified in parameter 3706 disabled (0)/
enabled (1) (Always specify 0.)
#6 DPS : Display of actual spindle speed the hob–axis
(0)/the spindle speed (1) speed is displayed.
