Comment
; Leading spindle = master spindle = spindle 1
; Following spindle = spindle 2
; Leading spindle rotates at 500 rpm
; Following spindle rotates at 300 rpm
; Dwell time of master spindle
; Coupling factor with ratio -1:1
; Activate coupling. The speed of the following spindle is determined
; by the speed of the leading spindle and the coupling factor.
; Programming a difference in speed
Comment
; Leading spindle = master spindle = spindle 1
; Following spindle = spindle 2
; Leading spindle rotates at 100 rpm, following spindle at 200 rpm
; Dwell time = 5 seconds of master spindle
; Transformation ratio of FS to LS is 1.0 (default)
; On-the-fly coupling to the leading spindle
; Following spindle rotates at 100 rpm
