Newport releases three-axis motion controller and driver
Oct 31 08 - Newport Corp. (Irvine, CA) has released the ESP301 three-axis motion controller and driver, the successor of the ESP300 motion controller. Because it provides the same functionality as the ESP300 with a supplemental, standard USB interface and extended front panel functions, the ESP301 is an good solution for a wide range of motion applications.
The ESP301 can drive and control up to three axes of motion using any combination of DC or 2-phase stepper motors up to 3A per axis. It uses a 64-bit, floating point, DSP processor for high precision synchronized control. A digital PID-FF (feed-forward) servo loop ensures precise velocity profile tracking and accurate positioning. A 1000x programmable micro-step resolution provides ultra-smooth low-speed stepper positioning capability, and 18-bit DC motor command output ensures improved stability for precision applications.
3D Systems Corporation, a provider of 3D printing, rapid prototyping, and manufacturing solutions, announced that more than 400 people from 35 countries attended its second annual World Conference from October 20-23, 2008, in Charlotte, NC/Rock Hill, SC.
