8.1 Overview
The gantries of the SIPLACE D machines each consist of an X and a Y axis. The Y-axis is driven by a
linear motor with integrated temperature sensor. The X axis is driven by a three-phase servo motor,
equipped with an integrated temperature sensor, and a belt. When viewed from the direction of transport,
the Y motors move from the right to the left side in positive counting direction and the X motors move
from the input conveyor to the output conveyer in positive counting direction. The placement heads are
mounted on the head plates of the respective X axis.
