    PDX1 Piezo Inertia Drive Stage with Optical Encoder Chapter 2: Safety 2.3. General Cautions CAUTION Dust and debris can reduce the lifetime of the stage. If left running unattended for extended periods of time, the application should be covered where possible.

  • Page 8: Chapter 3 Overview

    3.1. Introduction The PDX1(/M) stage features a piezo inertia motor that uses friction and inertia to translate the platform in discrete cycles. Each cycle consists of a relatively slow piezo expansion step accompanied by a rapid piezo contraction step. During the expansion step, the moving platform moves in the same direction as the piezo element due to friction, while the rapid piezo contraction causes the moving platform to slip and remain immobile due to inertia.

    Unpack the stage with care, checking the contents for signs of damage. If there is any sign of damage or missing parts, contact Thorlabs immediately. Please do not touch the optical scale when unpacking the stage. If necessary, clean the scale using N-heptane or isopropyl alcohol on a dust-free cloth.

    3.5. Accessories The PD1B(/M) adapter provides a flat surface for mounting the PDX1(/M) stage. The PD1T(/M) adapter plate features a central 8-32 (M4) tapped hole. Both imperial and metric versions have four 4-40 tapped holes on 16 mm spacings for 16 mm cage systems.

  • Page 11: Chapter 4 Installation

    Mount the PDX1(/M) stage on an even surface. The recommended flatness of the surface is ≤5 μm. For applications with large temperature variation, only mount the PDX1(/M) stage on a surface that has the same or similar thermal expansion properties as the stage.
  • Page 12 PDX1 Piezo Inertia Drive Stage with Optical Encoder Chapter 4: Installation Thorlabs offers a standard mounting plate, PD1B(/M), to provide a flat surface for mounting the stage and a 1.00" (25.0 mm) long #8 (M4) counterbored slot for mounting the plate to an optical table or breadboard.

  • Page 13: Attaching Shipping Plate

    A thin shipping plate is included with each stage to provide a convenient means of locking the stage's moving world (carriage plate) using three M1.4 cap screws (also included). 1. Align the shipping plate included in the package with the mounting holes in the side of the PDX1(/M) stage, as shown below.

    PDX1 Piezo Inertia Drive Stage with Optical Encoder Chapter 4: Installation 4.1.4. Mounting Components to the Stage CAUTION Do not exceed the load capacity specified in Chapter 6. The load’s center of mass should be over the platform. Do not use screws and dowel pins that protrude past the maximum hole depth.
  • Page 18 Thorlabs offers a thin mounting adapter plate, PD1T(/M), to provide a convenient means of attaching a load to the PDX1(/M) series stages by a central 8-32 (M4) tapped hole and other 4-40 (M2 & M3) tapped holes. Both imperial and metric versions have four 4-40 tapped holes spaced for 16 mm cage systems. The following is an example to show how to mount a PD1T(/M) plate to a PDX1(/M) stage.
  • Page 19 PDX1 Piezo Inertia Drive Stage with Optical Encoder Chapter 4: Installation Thorlabs also offers a thick mounting adapter plate, PD1U(/M), to provide a convenient means of attaching a load to the PDX1(/M) stages using five #8 (M4) counterbores, as shown below: 1.

  • Page 20: Electrical Connections

    The stage is shipped with a 1.5 m (5.0 ft) cable that is terminated in a 15-pin D-SUB female connector. Connect the PDX1(/M) stage to the 15-pin D-SUB male terminal on the front panel of the PDXC controller. For pin-out details, refer to the PDXC controller manual.

  • Page 21: Chapter 5 Operation

    Confirm the configuration of the PDXC controller prior to use. Since the controller can drive both PD1(/M) and PDX1(/M) stages, the wrong configuration will not drive the stage properly and there is a risk of damage to the stage and/or the controller.

  • Page 22: Maintenance

    Periodic maintenance helps to ensure the optimum stepping performance during its life span. NOTE The PDX1(/M) stage is assembled with rust preventative oil. Do not wipe the stage with organic solvents. When necessary, clean the surfaces of the stage with a dry, dust-free cloth.
