The National Instruments 778440-08 Motion Controller is a high-performance device engineered for both simple and complex motion applications. Belonging to the PCI-7358 Model series, this controller excels in sophisticated motion control for up to eight axes. It supports various motion types including vector space, point-to-point, linear, and circular trajectories, ensuring versatility for diverse automation tasks. The controller features sinusoidal commutation, enabling smooth and precise regulation of brushless motors, while also accommodating both stepper and servo motors in open or closed loop configurations. Compatible with a broad array of servo devices, the 778440-08 facilitates full, half, and microstepping for stepper axes.

Designed with advanced dual-processor technology, this motion controller provides embedded real-time control, enhancing high-speed communications and relieving the host PC of complex motion processing. It integrates improved PID control loop and PIVff control loop functionalities, which optimize servo update rates and command throughput, thereby maximizing overall system performance. Each axis is equipped with dedicated motion I/O for limit and home switches, along with additional non-dedicated user I/O, which includes digital inputs, analog inputs for ±10 V signals, joystick interfaces, and analog sensor monitoring.

To enhance synchronization across National Instruments products, the 778440-08 supports Real-Time System Integration (RTSI) bus, allowing seamless communication for motion, image collection, and data acquisition operations. The controller is complemented by user-friendly programming interfaces, including add-on motion VI libraries for LabVIEW and intuitive software tools, enabling users to define acceleration and velocity profiles for each axis and initiate simultaneous motion control across all axes with the NI-Motion driver software.
