PiezoMotor: Piezo LEGS® Controller PMD401

Piezo Motor Motion System

The PMD401 is a fully featured miniature controller for open loop and closed loop operation that can be easily stacked to form a multi-axis controller system.

It can be connected to the customer’s mainboard for integration in OEM applications. Host communication is done via 2-wire RS485 through ASCII commands. The PMD401 can also be used as a servo amplifier where the external controller regulates the speed via an SPI interface.

A breakout board with terminal blocks for easy access to power and communication is offered optionally for customers who want to get application development started straight away. It provides sub-nanometer resolution and speed in the mm/s range.
