X-axis position detection section
In order to detect the X-axis position, photointerrupters (sensor) are installed
at the right and left stroke end limit.
NOTICE
The machine uses photointerrupters to detect an axis position.
The photointerrupter provides the reference for the axis origin
position. If the axis origin is displaced from its proper position, this
may lead to a failure of the machine. Therefore, if any associated
parts need to be replaced, contact your nearest DISCO Service
Office.

- Provides the reference position for
initialization, setup, cutting and
alignment operations.
- Detects the right end limit of the X-
axis maximum stroke.
- The reference (origin) position is
located at 9.5mm left of right soft-
end, which is fixed at 0.5mm left of
the right-end sensor.
Left-end sensor Leftward stroke
