Motion Controller, ESP301, 1-Axis, GPIB, USB, RS232

The ESP301-1G 1 Axis Motion Controller and Driver is the successor of the popular ESP300 motion controller. The ESP301 provides the same functionality as the ESP300 with a standard USB and GPIB interface and extended front panel functions. For maximum backward compatibility, the ESP301 features the same motion commands and control algorithms and the same casing as the ESP300. The ESP301-1G drives and controls one axis of motion using DC or 2-phase stepper motors up to 3A. This capability enables driving a large selection of Newport stages and actuators. Featuring an integrated manual front panel interface and Newport's unique ESP stage auto-detection and auto-configuration, the ESP301 provides most easy operation and excellent functionality at an affordable price. The ESP301 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.
