2.1 Intended Use
The P-54x is a laboratory device as defined by DIN EN 61010-1. It is intended for indoor use and
use in an environment that is free of dirt, oil, and lubricants.
According to its design, the P-54x is intended for fine positioning as well as moving small objects
quickly and precisely. The specifications for the P-54x apply to horizontal mounting. Depending
on the version, moving is done as follows:
Model Motion Axis
.2xx
In two axes horizontally
X, Y
.Zxx
In one axis vertically
Z
.Txx In one axis vertically and in two axes rotationally Z, θX, θY
The P-54x can only be used as intended in conjunction with suitable electronics (p. 12) available
from PI. The electronics are not in the P-54x's scope of delivery.
The electronics must provide the required operating voltages. To ensure proper performance of
the servo control system, the electronics must also be able to read out and process the signals
from the position sensors.
2.2 General Safety Instructions
The P-54x is built according to state-of-the-art technology and recognized safety standards.
Improper use can result in personal injury and/or damage to the P-54x.
Use the P-54x for its intended purpose only, and only when it is in perfect technical
condition.
Read the user manual.
Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the P-54x.

6 Version: 1.2.0 PZ244E P-54x Nanopositioner
The P-54x is driven by piezo actuators. Temperature changes and compressive stresses can
induce charges in piezo actuators. After disconnection from the electronics, piezo actuators can
remain charged for several hours. Touching or short-circuiting the contacts in the connector of
the P-54x can lead to minor injuries from electric shock. The piezo actuators can be destroyed
by an abrupt contraction.
Do not open the P-54x.
Discharge the positioner's piezo actuators before installing:
Connect the positioner to the switched-off PI electronics equipped with an internal
discharge resistor.
Do not pull the plug connector out of the electronics during operation.
Positioners with D-sub plug connector:
Touching the contacts in the plug connector can lead to an electric shock (max. 130 V DC) and
minor injuries.
Do not touch the contacts in the plug connector.
Use screws to secure the positioner's connector against being pulled out of the
electronics.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-54x in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-54x can result in minor injuries from electric shock.
Connect the P-54x to a protective earth conductor (p. 18) before starting.
Do not remove the protective earth conductor during operation.
If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-54x to the protective earth conductor before restarting.
Mechanical forces can damage or misalign the P-54x.
Avoid impacts that affect the P-54x.
Do not drop the P-54x.
Do not exceed the maximum permissible stress and load capacities according to the
specifications (p. 35).
Do not touch any sensitive parts (e.g., platform) when handling the P-54x.
The P-54x is maintenance-free and achieves its positioning accuracy as a result of the optimal
alignment of mechanical components and piezo actuators. Loosened screws cause a loss in
positioning accuracy.
Loosen screws only when instructed in this manual.
Do not open the P-54x.

supplements or technical notes.
If you give the P-54x to a third party, include this user manual as well as other relevant
information provided by the manufacturer.
Do the work only if the user manual is complete. Missing information due to an
incomplete user manual can result in minor injury and damage to equipment.
Install and operate the P-54x only after you have read and understood this user manual.

3.7 Technical Features
3.7.1 PICMA® Piezo Actuators
P-54x positioners are driven by PICMA® piezo actuators. PICMA® actuators have all-ceramic
insulation and their performance and lifetime are therefore far superior to conventional
actuators. The ceramic insulation layer protects the monolithic piezoceramic block against
humidity and failure due to increased leakage current. In this way, an especially high reliability
is achieved even under extreme ambient conditions. In contrast to motorized drives, there are
no rotating parts or friction. The piezo actuators are therefore free of backlash, maintenance,
and wear.
3.7.2 Flexure Guides
P-54x positioners have flexure guides for friction-free motion and high guiding accuracy.
A flexure guide is an element that is free of static and sliding friction. It is based on the elastic
deformation (bending) of a solid (e.g., steel) and does not have any rolling or sliding parts.
Flexure elements have a high stiffness and load capacity. Flexure guides are maintenance and
wear free. They are 100 % vacuum compatible, function in a wide temperature range and do
not require any lubricants.
3.7.3 Position Sensors
Depending on the model (p. 9), the P-54x is equipped with capacitive or strain gauge sensors for
closed-loop operation.
Capacitive sensors
Capacitive sensors measure the position directly on the platform (direct metrology) and work
without contact. Neither friction nor hysteresis interferes with the motion, which allows
excellent linearity values to be achieved together with the high position resolution. In
conjunction with suitable electronics, capacitive sensors achieve the best resolution, stability,
and bandwidth.

3 Product Description
14 Version: 1.2.0 PZ244E P-54x Nanopositioner
Strain gauge sensors (SGS)
Strain gauge sensors derive the position information from their expansion. They are attached at
a suitable position in the drivetrain, where they measure the displacement of the positioner's
moving part against the base body. This type of position measuring is indirect and requires
contact, because the position of the platform is derived from a measurement on the lever,
guide or piezo stack.
The sensors operate in thermally drift-free full bridge circuitry and therefore ensure optimum
position stability in the nanometer range.
3.7.4 ID Chip (Models with D-sub Connector Only)
An ID chip is located in the D-sub connector of the P-54x. When the P-54x is calibrated at the
factory with digital electronics, the calibration data is saved on the ID chip together with
specific product information. During switch-on, the digital electronics read the data from the
ID chip of the P-54x connected. A P-54x with an ID chip containing calibration data can
therefore be connected to any suitable digital electronics without renewed calibration.
Refer to the manual for the controller for more information on the ID chip.

4 Unpacking
P-54x Nanopositioner PZ244E Version: 1.2.0 15
NOTICE
Mechanical overload due to incorrect handling!
An impermissible mechanical load on the platform of the P-54x can cause damage to the piezo
actuators, sensors, and flexures of the P-54x as well as loss of accuracy.
Do not touch any sensitive parts (e.g., platform) when handling the P-54x.
1. Unpack the P-54x with care.
2. Compare the contents with the scope of delivery according to the contract and the
delivery note.
3. Inspect the contents for signs of damage. If any parts are damaged or missing, contact
our customer service department (p. 33) immediately.
4. Keep all packaging materials in case the product needs to be returned.
