Piezo LEGS® Controller PMD401

PMD401 — Printed Circuit Board

A fully featured miniature closed loop controller board that can be easily stacked to form a multi-axis system. It provides resolution in the sub-nanometer range. Can also be used as a servo amplifier together with an external motion controller.

  • Small board for close integration

    The PMD401 is a fully featured miniature controller board for open loop and closed loop operation that can be easily stacked to form a multi-axis controller system, and piggy-backed on customers mainboard for integration in OEM applications. It can provide resolution of up to 8192 microsteps, corresponding to positioning resolution in the sub-nanometer range. Host communication is 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 SPI interface. A breakout board with terminal blocks for easy access to power and communication is offered optionally for customers wanting to get application development started straight away.
