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 • 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.

Installation Guidelines for Piezo LEGS® Caliper Mounting instructions • Step one is to remove transport safety holder. 3 (2x) -0,002 3 g7 -0,012 • • CAUTION! Driving the motor outside of limits, or in other ways displacing the drive rod away from the drive legs, will damage the motor permanently. When designing the parts you must include mechanical end stops to prevent stage from moving outside of the specified limits. • • In the illustration below the different parts are named for reference. The illustration also shows cable and its dimensions. Guide pin Drive rod holder Motor base Cable...

Installation Guidelines for Piezo LEGS® Caliper • Bottom side up. Feed cables through the holes on the stage block.

Installation Guidelines for Piezo LEGS® Caliper • Slide motor in place. Make sure the Guiding Pins are entering the guiding holes in the stage top block.

Installation Guidelines for Piezo LEGS® Caliper • Turn the stage over, top side up. Mount screws (4 x M2) to fixate the Drive Rod Holder. Tighten screws crosswise. • • CAUTION! For the motor to work properly it is very important to mount the top side screws first.

Installation Guidelines for Piezo LEGS® Caliper • Turn the stage over, bottom side up. Adjust the bottom block to center Motor Base lengthwise. • • CAUTION! It is very important that the Motor Base is self aligned. Do not force motor in any direction. Insert screws (4 x M2) and tighten them crosswise without disturbing the self aligned position of the Motor Base. • The cables needs to be secured with cable relief (of your design). • • CAD files of motors in both versions, and mock-up stage units are downloadable from the PiezoMotor webpage: www.piezomotor.com
