3.2 Function and application
The planar surface gantry contains two servo motors which drive a H-shaped rotating toothed belt. The
toothed belt moves a slide with recirculating ball bearing guides. The position of the slide is calculated
by the controller from the encoder signals of the motors.
The motors are not directly assigned an axis (X- or Y-axis) of the planar surface gantry. Instead, the
movement of the slide towards an axis is achieved through the interaction of the two motors, which is
controlled by the controller (Fig. 3.1).
The planar surface gantry is designed for executing positioning tasks within machines or automated
systems with a higher-order controller.
3.3 Functional principle
The EXCM-30 planar surface gantry moves a slide in a 2-dimensional space by means of a shared
toothed belt.

4.1 Preparations for mounting
4.1.1 Mounting position
Warning
The use of the planar surface gantry without a motor brake in a mounting position other
than horizontal can result in uncontrolled movements of the attached load.
Freely movable loads can result in injury to people and damage to the peripherals of the
planar surface gantry.
• Use a planar surface gantry without motor brake (EXCM-30-…-ST-…) exclusively in a
horizontal mounting position.

4.1.2 Requirements of the mounting surface
The following conditions must be met, otherwise the range of functions may be restricted:
General requirements
– sufficient space for movement of the planar surface gantry
– planar surface gantry mounted in a torsionally rigid and tension-free manner
– flat bearing surface (flatness š0.1 mm/m²)
– full-surface support of the two profiles of the planar surface gantry
– sufficient attachment to absorb the maximum forces (4.1.5 Number of profile mountings)
Additional requirements for motors flanged at the bottom (EXCM-30-…-B…)
– cut-outs in the mounting surface for the motors (dimensions www.festo.com/catalogue)
