The Newport ESP300-11N11N is a compact motion controller and driver that combines control and drive functionality into a single unit for precise positioning across up to 3 axes. Built on a 32-bit floating-point DSP processor, it delivers synchronized multi-axis motion with 1000x programmable micro-stepping resolution for stepper motors and digital PID feed-forward servo control for DC brush motors. The system executes complex motion profiles including point-to-point positioning, linear/circular interpolation, continuous path contouring, and electronic axis slaving—all with on-the-fly trajectory modification capability.
