Description: 3
The head mounting plate with the C&P head or TWIN-head is moved via the linear guidance which
are mounted over the secondary part of the linear motor and under the secondary part of the linear
motor in X direction. The Y- axis moves the entire X-axis with the C&P or TWIN-head.
For X and Y position recognition we use incremental metal scales. They are positioned over the
secondary part of the X - Linear motor and under the secondary part of the Y- Linear motor. A cor-
responding incremental encoder reads the increments from the metal scales and generates track
signals as a result. The encoder transmits the track signals to the axis control card, which uses
the track signals to determine axis position and to control the motor.
Left and right of every incremental scale are mounted the metal actuators for the BERO´s. The
BERO‘s on the X- and Y- axes are required for the reference run, the velocity check and the
hardware limit switch.
Additionally each axis has a mechanical end stop (elastomer bumper).

– Cooling the Y- axes occurs via a motor which generate compressed air it is mounted in the
pneumatic unit.
– The X axes are cooled from the C&P head or Twin head with exhaust of the vacuum system.
