Piezo LEGS® Controller PMD301

PMD301 — Boxed

A versatile standalone packaged controller unit with inbuilt functions to operate Piezo LEGS® motors in closed loop (target mode) or open loop with sub-nanometer resolution. Multiple units can be easily chained to form multi-axis systems with host communication over serial RS485. An external motion controller may control the speed via SPI or analog interface.

  • Rugged controller for industrial use

    The PMD301 is a versatile standalone packaged controller unit with inbuilt functions to operate Piezo LEGS® motors in closed loop (target mode) or open loop. It provides resolution of up to 8192 microsteps, corresponding to positioning resolution in the sub-nanometer range. Multiple units can be easily chained to form multi-axis systems. 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 and as a servo interface. An external motion controller may control the speed via SPI or analog voltage interface.
