Outstanding lifetime due to PICMA® piezo actuators
The PICMA® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA® actuators offer an up to ten times longer lifetime than conventional polymer-insulated actuators. 100 billion cycles without a single failure are proven.
Nanometer precision and high feed force with PiezoWalk® walking drives
In the PiezoWalk® walking drive, several piezo actuators do a walking motion that leads to a forward feed of a runner. Control of the actuators allows the smallest step and forward feed motion at a resolution of well under one nanometer.
Highly accurate position measuring with incremental linear encoder
Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.

Travel range in X, open loop: From one mechanical hard stop of the runner to the other mechanical hard stop, only in open-loop operation
Velocity (100 % duty cycle, full-step mode): depends on the controller, the load, and the servo parameters: in this case an E-712.AN controller is used. For longer positioning processes, operate the linear actuator with this controller at a velocity below 3 mm/s.
Operating frequency in full-step mode: when operated with a digital controller with 25 W peak power output
All specifications based on room temperature (22 °C ±3 °C).
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

기술
PICMA® Technology
Highly reliable and extended lifetime through the patented manufacturing process for multilayer actuators.
PiezoWalk® Walking Drives
PiezoWalk® drives were developed more than 10 years ago for the semiconductor industry, a demanding industry when it comes to reliability, position resolution and long-term stability.
Vacuum
Careful handling, adequate premises: PI does not only have the necessary equipment for the qualification of materials, components and final products, but also has many years of experience with regard to HV und UHV positioning systems.
Digital Motion Controllers
Digital technology opens up possibilities for improving performance in control engineering which do not exist with conventional analog technology.
Incremental Sensors
PI uses incremental measurement systems for longer travel ranges, starting from approximately one millimeter. These sensors, which in most cases are optical sensors, achieve position resolution down to the picometer range.
Hexapods and SpaceFAB
Hexapods are systems for moving and positioning loads in six degrees of freedom, in three translational and three rotational axes.
