    PDXR1(/M) Piezo Inertia Drive Rotation Stage with Optical Encoder Chapter 1: Safety Chapter 1 Safety Safety Information For the continuing safety of the operators of this equipment, and the protection of the equipment itself, the operator should take note of the Warnings, Cautions, and Notes throughout this manual and, where visible, on the product itself.
  • Page 4 PDXR1(/M) Piezo Inertia Drive Rotation Stage with Optical Encoder Chapter 1: Safety General Warnings Warning If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. In particular, excessive moisture and/or dust may impair operation.

  • Page 5: Chapter 2 Overview

    Overview Introduction The PDXR1(/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.
  • Page 6 The bottom surface features five #8 (M4) counterbores, providing a convenient means of attaching a load to the stage. PD1U(/M) mount on rotation platform of PDXR1(/M) via 2 pieces of M2(2-56) tapping holes in diagonal direction of rotation platform.

  • Page 7: Chapter 3 Installation

    Take care to securely mount the stage before attaching components to the stage’s rotation platform. Mount the PDXR1(/M) stage on an even surface. The recommended flatness of the surface is ≤5 μm. For applications with large temperature variations, only mount the PDXR1(/M) stage on a surface that has the same or similar thermal expansion properties as the stage.

  • Page 8: Mounting On A Base

    3.1.2 Mounting on a Base The PDXR1 and PDXR1/M stages can mounted onto the MSB34 & MSB7510/M high-density optical breadboards, respectively. The breadboard provides a flat surface for mounting the stage and four 1/4" (M6) counterbored holes for mounting to an optical table or standard breadboard.

    PDXR1(/M) Piezo Inertia Drive Rotation Stage with Optical Encoder Chapter 3: Installation 3.1.3 Post Mounting The stage can be mounted vertically on a Ø1/2" post via the 8-32 (M4 x 0.7) tapped hole on the side opposite the cable exit.

  • Page 10: Setting Up An Xy + Rotation Stage Configuration

    Setting Up an XY + Rotation Stage Configuration This section describes how to build an XY + rotation stage using two PDX1(/M) linear stages and a PDXR1(/M) rotation stage. Note that the PDX1(/M) stages will need to be translated to access the mounting holes, which can be done using a PDXC controller.

  • Page 11: Mounting Components To The Stage

    PDXR1(/M) Piezo Inertia Drive Rotation Stage with Optical Encoder Chapter 3: Installation 3.1.5 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 12 Thorlabs offers a thin mounting adapter plate, PD1T(/M), to provide a convenient means of attaching a load to the PDXR1(/M) stage by a central 8-32 (M4 x 0.7) threaded hole and other 4-40 (M2 x 0.4 & M3 x 0.5) threaded holes.
  • Page 13 PDXR1(/M) Piezo Inertia Drive Rotation Stage with Optical Encoder Chapter 3: Installation Thorlabs also offers the thick PD1U(/M) mounting adapter plate which provides a convenient means of attaching a load to the PDXR1(/M) stages using five #8 (M4) counterbores, as shown below: 1.
  • Page 14 Before driving the PDXR1(/M) stage, the configuration of the PDXC controller must be set correctly. The controller can drive components using SMC and D-Sub connectors. The PDXR1(/M) stage only works in D-Sub mode and in either open- or closed-loop mode. Users can toggle between these two modes using the knob on the front panel of the controller during controller startup.

  • Page 15: Chapter 4 Operation

    Confirm the configuration of the PDXC controller prior to use. Since the controller can drive both PD Series stages with SMC connectors and PDXR1(/M) stages with D-Sub connector respectively, the wrong configuration will not drive the stage properly and there is a risk of damage to the stage and/or the controller.
  • Page 16 Periodic maintenance helps to ensure the optimum stepping performance during its life span. Note The PDXR1(/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.
