PI (Physik Instrumente) L.P has expanded its E-709 family of low-cost digital piezo nanopositioning controllers with a new plug-in module for the C-885 PIMotionMaster modular controller system.
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.
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 fifth-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.
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
Fields of applications include precision motion control in automation, nanopositioning, photonics, semiconductor testing, laser machining.

laser machining
Intensified, pulsed beams of light generated by lasers—typically carbon dioxide or neodium-doped yttrium aluminum garnet (Nd:YAG)—that drill, weld, engrave, mark, slit and caseharden. Usually under CNC, often at both high cutting rates (100 linear in./sec.) and high power (5kW or more). Lasers also are used in conjunction with in-process quality-control monitoring systems allowing measuring accuracies of 0.00001".
