Multi-axis motion controller PMD301

DCfor piezoelectric unitsrugged

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.
