The Newport ESP300-NNN1NN is a three-axis motion controller and driver that combines control and drive electronics into a single chassis. It delivers synchronized multi-axis positioning for DC servo and stepper motor applications in research, automation, and industrial environments. The 32-bit floating-point DSP processor executes digital PID-FF servo loops for precision velocity tracking and point-to-point positioning.
