Comment
; Leading spindle = master spindle = spindle 1
; Following spindle = spindle 2
; Leading spindle rotates at 3,000 rpm,
; following spindle rotates at 500 rpm
; Def. of the coupling (can also be configured)
; Bring leading spindle into closed-loop position control
(setpoint coupling)
; Bring following spindle into closed-loop position control
; On-the-fly coupling to offset position = 45 degrees
; Positioning speed = 100 degrees/min
; Traverse with 90° overlay in negative direction
; Wait for "fine" synchronism
; Machining
; Traverse with 180° overlay in the positive direction
; Dwell time = 50 revolutions of the master spindle
; Activate configured velocity (MD)
; 20 revolutions With configured velocity in
; negative direction
; Couple-out on-the-fly, S=S2=3000
; Stop FS at zero degrees
;
; Wait for spindle 2
; Stop FS
