Digital servo controller for piezo inertia drives

Integrated power amplifier and voltage generator for piezo inertia drives. Point-to-point motion, trapezoidal velocity profile, actuator mode for nanometer precision positioning at the target position. 1 axis.

Encoder inputs

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


USB, RS-232, and TCP/IP (depends on version) for commanding. I/O lines (analog/digital) for automation. Interface for analog joystick.

Extensive functions, software support

Powerful macro command language. Nonvolatile macro storage, e.g., for stand-alone operation with autostart macro. Data recorder. ID chip detection for fast startup. PID controller, parameter changing during operation Extensive software support, e.g., for LabVIEW, C, C++, MATLAB, python. PIMikroMove user software.
