Installation Guidelines for Piezo LEGS® Caliper
The Piezo LEGS Caliper is a high precision motor made for stage integration. The
motor comes in one version for gonimeter stages and in a second version for linear
stages. Design of surrounding mechanics have to be done with guidance from the
drawings in this document, keeping within the given tolerances. Performance as well
as life time will be severely affected if motor is not installed with great care. The
illustrations below show examples of what kind of stages to build for the Piezo LEGS
Caliper to be fitted inside.
Piezo LEGS® Caliper
Gonio version - LC2010
Piezo LEGS® Caliper
Linear version - LC2020
•t The Piezo LEGS Caliper is mounted inside the stage unit using 8 screws. The
example above shows both versions of the motor (for goniometer stage and for
linear stage).
• CAUTION! The Piezo LEGS Caliper motor cannot be driven without guidance from
surrounding mechanics. The drive rod must not be removed from the motor, and it
must not be moved to a position where contact with any drive leg is lost. The drive
legs will be severely damaged if they are not preloaded while motor is running.
Repositioning a drive rod that has come out of place may crack the ceramic drive
legs. Keep transport safty holder on the motor until you are ready to mount.
