3.1.6.3 Spindle Positioning Mechanism
A sensor tracks the spindle rotation motion and feeds the positioning signal to the spindle
motor controller which accurately controls the spindle position.

3.1.7 Feed Motion Transmission Mechanism
The encoder monitors the position of the feed motion in a semi-closed loop. You can, however,
select linear scales if installed (optional part), which is a fully closed control loop.
3.1.7.1 X-Axis Feed-motion Transmission Mechanism
The table sits on the guide rails of the saddle and is driven by the AC servo motor through the
connection of a coupling and a ballscrew.
Limit switches stop the saddle from over-travelling. When the working table travels over the
limit, the positioning blocks operate the limit switch on the saddle. The limit switch transmits
the over-limit signal to the AC servo motor's controller to stop the feed motion.
