E-873.1AT, dimensions in mm

Single-axis benchtop device for piezoelectric inertia drives.

USB, RS-232, TCP/IP, and SPI for commanding. I/O lines (analog/digital) for automation. Connector for analog joystick.

Technology

Integrated power amplifier and voltage generator for piezoelectric inertia drives. Point-to-point motion, trapezoidal velocity profile, actuator mode for nanometer-precise positioning at the target position.

Differential signal transmission for digital (A/B) or analog (sin/cos) encoder signals. BiSS interface for absolute encoders. TTL inputs for limit and reference switches.

Functionality and software

Powerful macro programming language. Nonvolatile macro memory, e.g., for stand-alone operation with autostart macro. Data recorder. ID chip detection for fast startup. PID controller, parameters modifiable during operation.

Extensive software support, e.g., for NI LabVIEW, C, C++, MATLAB, Python. PIMikroMove user software.
