Positioning or axis mode
If the following spindle is in positioning or axis mode before coupling, then the following
spindle behaves the same for
Note
Leading spindle and axis operation
If, prior to the coupling being defined, the leading spindle is in axis operation, the velocity
limit value from machine data
MD32000 $MA_MAX_AX_VELO (maximum axis velocity) will still apply even after the
coupling is activated.
To avoid this behavior, the axis must be switched to spindle mode (
to the coupling being defined.

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 leading spindle and
transfer previous speed to S2.
S2 rotates at 100 rpm + 200 rpm = 300 rpm
Comment
Leading spindle = master spindle = spindle 1
Following spindle = spindle 2
Following spindle S2 in positioning mode.
Transformation ratio of FS to LS is 1.0 (default).
On-the-fly coupling to the leading spindle.
Coupling is closed, S2 stops at 20 degrees.
