The Newport ESP100 is a single-axis motion controller and driver integrated into one compact chassis, delivering sub-micron positioning precision for stepper and brush DC servo motors. Operating at 1A maximum drive current with a 32-bit floating point, 60MHz DSP microprocessor, it executes both open-loop and closed-loop control with encoder feedback. The unit accepts user-configurable motion profiles for acceleration, deceleration, and velocity, plus built-in scripting for automated, repeatable operations.
