JANUARY 27, 2009--The ESP301 motion controller and driver provides the same functionality as the ESP300 motion controller with a supplemental, standard USB interface and extended front-panel functions. The controller can drive and control up to three axes of motion using any combination of DC or two-phase stepper motors up to 3 A per axis. It uses a 64-bit, floating point, DSP processor for precision synchronized control. A digital PID-FF (feedforward) servo loop ensures velocity profile tracking and positioning accuracy. A 1000X programmable microstep resolution provides smooth, low-speed stepper positioning and 18-bit DC motor command output offers stability. Positioning modes include synchronized and non-synchronized point-to-point, jogging, linear or circular interpolation, and continuous path contouring.

PRESS RELEASE

Newport Announces the New ESP301 Three-Axis Motion Controller and Driver

Irvine, CA - Oct. 29, 2008 - Newport Corporation, a worldwide leader in lasers and photonics solutions, today announced the ESP301 three axis motion controller and driver. The ESP301 is the successor of the popular 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 excellent solution for a wide range of motion applications.

Beda Espinoza, Product Line Manager for Newport's motion products stated, "We are very pleased to announce the ESP301 because we believe it offers significant benefits to our customers. It offers faster USB communication and a cleaner, more intuitive front panel menu. In addition, the ESP301 also offers the same industry-leading reliability as the ESP300 with better robustness. With an integrated manual front panel interface and Newport's proprietary, unique ESP stage auto-detection and auto-configuration, the ESP301 provides simple operation and excellent functionality at an affordable price."

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.

The ESP301 provides several modes of positioning including synchronized and non-synchronized point-to-point, jogging, linear or circular interpolation, and continuous path contouring. With electronic gearing, any axis of the ESP301 can be "slaved" to any other axis, even if they have different motor/gear ratios or lead screw pitches. Other sophisticated motion features include on-the-fly position, velocity, or trajectory changes for complex motion and alignment routines. Software limits can be set to improve systems safety. An advanced origin search routine includes encoder index pulse consideration for precision homing. Backlash and linear error compensation eliminate repeatable system errors.
