7.2.2.2 Feed-Motion Positioning Mechanism
7.2.2.2.1 The encoder equipped with the AC servomotor is used to track down the
feed motion positioning. This is only a semi-closed control loop.
Otherwise can selections the linear scales (option) which are a closed
control loop.
7.2.2.2.2 The maximum traveling range in the Y direction is 680mm ( AL52/AM52 ).
A safety mechanism is used to prevent the saddle from over-traveling as
described below.
7.2.2.2.3 When the saddle travels over the limit, the positioning blocks will touch
the limit switch on the saddle. The limit switch transmits the over-limit
signal to the AC servomotor's controller to stop the feed motion.
