Comment
Traverse with 180 degrees overlay in the posi-
tive direction.
Dwell time = 50 revolutions of the master spindle
Activate configured velocity (MD).
20 revolutions. Move with configured velocity in
the negative direction.
Couple-out on-the-fly, S=S2=3000
Stop FS at zero degrees.
Wait for spindle 2.
Stop FS.
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 results from the speed of the leading
spindle and 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 (de-
fault).
On-the-fly coupling to the leading spindle.
Following spindle rotates at 100 rpm.
