Operating Principle; Permitted Mounting Position - Festo EXCM-30 Instructions Manual

3 Product overview
3.2

Operating principle

Two fixed stepper motors drive a toothed belt arrayed in an H shape.
The toothed belt moves the Y-axis (traverse) and the slide located on the Y-axis (traverse) in a 2-dimen­
sional space. A controller calculates the position of the slide. The controlled interaction of the motors
results in the corresponding movement of the slide.

The depicted directions of movement of the Y-axis slide refer to the directions of rotation
of the motor of the functional principle shown.

Permitted 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.
