6.1 Overview
The SIPLACE D-series gantries consists of an X and Y axis each. The Y-axis is powered by a linear
motor with integrated temperature sensor. The X-axis is powered by a 3-phase servo motor, which is
fitted with an integrated temperature sensor and which is driven by a belt. When viewed in the direction
of transport, the Y motors move from left to right in a positive counting direction and the X motors move
from the input conveyor to the output conveyor, in a positive counting direction. The placement heads
are mounted on the head plates of the respective X axes.

Mechanical Structure
With the help of a toothed belt drive, the rotary movement of the X-axis motor is directly converted into
a lengthwise movement of the placement head, in the X-direction.
The linear guide rails under the X-axis guide the head assembly plate and the placement head along the
X-axis.
The X-motor is cooled by a fan at the Y-axis pickup position and the motor temperature is also monitored
by a sensor.
