1. 0BIntroduction
1.1 Product Description
The PP-18 is a low-cost piezo stage. Miniature cross-roller bearings assure high
stiffness. It utilizes our patent-pending multi-phase piezo motor resulting in high
speed (>2mm/s) and high blocking force (>1.5N).
Features:
▪Travel range of up to 51m
▪Load capacity up to 0.5 kg horizontally, 0.15 kg vertically
▪40 nm closed loop resolution standard

3. 2BPreparing to Install the PP-18
3.1 14BInstallation Preparation
When mounting the stage, it is important to consider the flatness of the mounting
surface, as the stage will conform to the shape of that mounting surface. A surface
that is not flat can adversely affect the performance and structural integrity of the
stage.
The stage is calibrated and guaranteed to be within specification at 20°C ±5°C
unless otherwise specified. Be sure to use the stage under the following conditions:
▪Mount to a clean and flat surface which is free of debris, burrs or dings
▪An indoor atmosphere free of corrosive gases, excessive dust, and
condensation
▪Temperature range of 0-40°C
▪Relative humidity between 20-80%
▪Locate away from water, heat, and electrical noise
3.2 15BPackage Contents
If product is damaged or there are missing components, contact MICRONIX USA
immediately. Do not discard product packaging in case of return shipment.
Package Should Contain:
▪PP-18 Linear Stage
▪Reference Manual
▪Any other previously agreed upon components such as a controller

4. 3BInstalling the PP-18
All mounting patterns require M2 screws for mounting and M1.5 x 5mm dowel pins
for precision alignment. Additional brackets and screws may be needed for
custom applications.

For X-Y mounting, follow the instructions for mounting the X-axis stage, outlined in
section 4.1.1 General Mounting, then proceed to mount the Y-axis stage, as shown
below (Please note, it is possible to move the carriage manually without damaging
the stage):
Note: For stages assembled in an XY configuration in factory do not require disassembly for
base mounting
Requires:
2x M1.5 x 4mm Dowel Pins

8. 7BSupplementary Information
8.1 21BMaintenance
•The PP-18 series of linear piezo stages utilizes a maintenance free design. Do not
modify the stage or perform any maintenance unless specifically instructed to do
so by MICRONIX USA personal. If the stage is not performing up to the original
specifications, please contact MICRONIX USA.
•The PP-18 linear piezo stage is a precision mechanical device and
should be handled with care. Do not drop or mishandle the stage.
•Do not touch the bearings, as this will contaminate the lubrication and jeopardize
the longevity of the stage.
•Follow the Installation Preparation requirements and use proper cable
management to ensure a clean and safe operating environment.
