- PWM Stepper C Series Motor Drive Module—The NI‑9503 is a single-axis module that adds integrated stepper motion control to a system without the need for an external power drive or connector block. The NI‑9503 provides seamless motion integration with a proven measurement and control platform. It features an advanced PWM algorithm that reduces torque ripple, minimizes power loss, and smoothes microstepping. The NI‑9503 also includes direct connectivity to two-phase bipolar or unipolar hybrid stepper motors, and it features software-programmable current reduction for reduced power consumption.
