Stepper, 1-Axis, Single Encoder C Series Motor Drive Interface Module—The NI‑9512 provides stepper drive interface signals for a single axis, a full set of motion I/O including inputs for a home switch and limit switches, incremental encoder inputs for position feedback, and general-purpose inputs and outputs. The NI‑9512 includes advanced motion features, such as position capture and position compare, as well as direct connectivity to P7000 series stepper drives. The NI‑9512 processor runs the spline interpolation engine and patented NI step generation algorithm to produce smoother motion, resulting in precise stepper motion control.
