Piezo system specialist PI
is switching to a new generation of 24-bit resolution interfaces for its nanopositioning
stage controllers. The new interfaces will allow better than 100 picometers
command resolution even on the latest generation long travel piezo nanopositioning
stages (1 mm and up) such as the PIHera™ series closed-loop flexure stages.

Several piezo controllers with the new 24-Bit interface: E-621 card, E-625 (bench-top), E-665 display controller and 12 x E-621 in an E-500 chassis (bottom)
1 to 12 Channels, Many Variations
The new controllers come in a variety of bench-top, rack-mount and OEM card
versions from single-channel units for simple linear actuator applications to
multi-axis system controllers with 12 channels per rack.
Extensive Software Support
The new piezo controllers come with Windows installation software, DLLs and
LabVIEW drivers. The extensive command set is based on the hardware-independent
General Command Set (GCS), common to all PI micro & nanopositioning systems.
GCS reduces the programming effort in the face of complex multi-axis positioning
tasks or when upgrading a system with a different PI controller.
New features include
- Integrated USB Interface, 24 bit DA converters
- Network Capability with up to 12 Channels
- Position Controller for Strain Gauge and Capacitive Sensors
- Notch Filter for Higher Bandwidth
- Additional Analog Interface
- Data Table for User-Defined Curves
