;Decouple on-the-fly, S=S2=3000
;Stop slave spindle at zero degrees
;Wait for spindle 2
;Stop slave spindle
;Leading spindle = master spindle =
;spindle 1
;Following spindle = spindle 2
;Master spindle rotates at 500 rpm
;Following spindle rotates at 300 rpm
;Dwell time of master spindle
;Coupling factor with speed ratio -1:1
;Activate coupling. The speed of the
;following spindle results from the speed
;of the main spindle and coupling factor
;Programming of difference in speed
;Leading spindle = master spindle =
;spindle 1
;Following spindle = spindle 2
;Master spindle rotates at 100 rpm
;following spindle at 200 rpm
;Dwell time = 5 seconds of master spindle
;Speed ratio of following spindle to
;main spindle is 1.0 (presetting)
;On-the-fly coupling to main spindle
;Following spindle rotates at 100 rpm
;Leading spindle = master spindle =
;spindle 1
;Following spindle = spindle 2
;Master spindle rotates at 100 rpm
;following spindle at 200 rpm
;Dwell time = 5 seconds of master spindle
;Speed ratio of following spindle to
;main spindle is 1.0 (presetting)
;On-the-fly coupling to main spindle and
;transfer previous speed to S2
;S2 rotates at 100 rpm + 200 rpm = 300 rpm
