Nanometer Resolution Motion Controller for Mini Piezo Motor Micrometer-Actuators

PI’s new digital servo motion controller specifically designed to drive compact opto-mechanical actuators.

PI (Physik Instrumente) L.P., known industry-wide for nanometer precision motion components, systems, and OEM solutions, announces a new compact closed-loop motion controller. The new E-871.1A1N digital servo controller is the latest model in a series of drivers and controllers specifically designed for inertia-motor based opto-mechanical actuators (piezo ratchet drives) that are widely used in the semiconductor, laser and photonics industry for fine-tuning of complex systems. The miniature actuators are often employed as "set-and-forget" mechanisms with an option to remotely make adjustments, where manual micrometer screws would necessitate a system-shutdown to allow for corrections. Other application fields include bio-nanotechnology, microscopy, and micro-manipulation.

Integrated Power Amplifier and Voltage Generator
The E-871.1A1N has an integrated power amplifier and voltage generator for piezo inertia drives and is optimized for PI's compact N-472 series of closed-loop PiezoMike precision actuators which provide high stability, long lifetime of more than 1 billion steps, and low cost of ownership.
Data Recorder, Auto-Calibration ID Chip, Quick Start Up, Comprehensive Software Package
The E-871.1A1N is equipped with a data recorder for high speed tracing, ID chip compatibility for quick start-up and exchange of system components without recalibration. The controllers are delivered with extensive software packages, including support for LabVIEW, MATLAB, C / C++ / C# / VB.NET and Python. In addition, a powerful macro programming language is available, for automation tasks and stand-alone operation. Communication with a host PC is via modern interfaces, such as TCP/IP and USB. An optional joystick is available for manual operation.
Ratchet Actuator Advantages
Actuators with a screw and ratchet mechanism are designed with a small piezo ceramic block that performs the individual "clicks" based on the input to a controller. The advantage of this design is a very high stiffness and blocking force of up to 100N (22 lbs). Once the encoder tells the controller that a position is reached, the actuator is vibration-proof, shock-resistant, and long-term stable, with no position drift or jitter.

IntervalZero’s RTX64

IntervalZero's RTX64

RTX64 turns the Microsoft 64-bit Windows operating system into a Real-time operating system (RTOS). RTX64 enhances Windows by providing hard real-time and control capabilities to a general purpose operating system that is familiar to both developers and end users. RTX64 consists of a separate real-time subsystem (RTSS) that schedules and controls all RTSS applications independently of Windows.RTX64 is a key component of the IntervalZero RTOS Platform that comprises x86 and x64 multicore multiprocessors, Windows, and real-time Ethernet (e.g. EtherCAT or PROFINET) to outperform real-time hardware such as DSPs and radically reduce the development costs for systems that require determinism or hard real-time.
