PiezoMotor: Piezo LEGS® Controller PMD301

Piezo Motor Motion System

The PMD301 is a 1-axis controller for use with Piezo LEGS® motors from PiezoMotor. Units can be chained to form multi-axis systems.

It provides sub-nanometer resolution and speed in the mm/s range. PMD301 is the ideal choice for system designs where one or several Piezo LEGS® motors are used.

Host communication is either via a 2-wire RS485 or USB virtual COM port through ASCII commands. A 15-pole D-Sub port can be configured for general I/O, sensor input or as a motion controller interface. An external motion controller may control the speed via SPI or analog voltage interface.
