PI Expands Its Family of Digital Piezo Nanopositioning Controllers

Integrating different drive technologies from traditional servo and stepper motors to highly specialized piezo-ceramic scanners is easy.

February 2018, Auburn, MA – Motion control and nanopositioning solutions provider PI (Physik Instrumente) L.P. has expanded its successful E-709 family of low-cost digital piezo nanopositioning controllers with a new plug-in module for the C-885 PIMotionMaster modular controller system.

Modular System, up to 20 Cards per Rack
The PIMotionMaster system allows the combination of different drive technologies, controlled through one interface via one software package. For example, stepper motor stages, closed-loop servo motor positioners, and fast piezo-driven nano-focus devices can now be operated from one controller. Up to 20 control cards can be plugged into one 19” rack

Digital Servo Controller with Piezo Power Amplifier and Software
The latest piezo control module, the E-709.1CC885, supports functions including wave generator, data recorder, auto zero, and I/O triggers. With a sensor update rate of 10kHz, two notch filters and linearization algorithms based on 5th-order polynomials it provides exceptionally accurate motion with sub-nanometer precision. The E-709 card combines a power amplifier (-30 to 130V output), signal conditioning circuitry for capacitance sensors and a digital servo. Piezo controllers with digital servo offer the advantage of higher linearity, and easy access to advanced features in comparison to conventional analog piezo controllers. A comprehensive software package is included: drivers for LabVIEW, dynamic libraries for Windows and Linux, MATLAB, MetaMorph, µManager, Andor iQ. Interfaces include USB, SPI, RS-232, and analog.

Plug & Play for Multiple Types of Motors and Drive Systems
After the modules are installed in the rack, individual axis configuration and movement is easily set-up using the included PIMikroMove software, a comprehensive Windows GUI that does not require programming knowledge for commissioning or direct operation.

Modules are currently available for PI translation/rotation stages equipped with:

  • DC motors
  • 3-phase motors
  • Stepper motors
  • Piezo flexure positioners
  • Piezo ultrasonic motors
  • PiezoWalk® nanopositioning motors
  • Piezo inertia motors
