The Newport ESP300-NNN11N is a single-axis motion controller/driver combining integrated control and drive electronics in a compact 2U rack-mountable or benchtop enclosure. It delivers precision positioning for stepper and brush DC motors with real-time command processing via a 32-bit floating-point DSP processor. The system executes complex motion profiles including synchronized/non-synchronized point-to-point positioning, jogging, linear and circular interpolation, and continuous path contouring—all with on-the-fly trajectory adjustment capability.
