In a Weihong CNC system, the PCIMC-3D is a motion control card (PCI interface) designed for 3-axis CNC machines (mills, routers, engravers). The Weihong CNC adaptor typically refers to the breakout or signal conversion board that connects the PCIMC-3D to external drivers, sensors, and spindle controls. Together, they form a closed-loop or open-loop motion control system.

The PCIMC card typically outputs signals via a high-density 68-pin or 37-pin D-sub connector. The adaptor breaks this single connector into separate, labeled terminal blocks for: In a Weihong CNC system, the PCIMC-3D is
Without this adaptor, the PCIMC is just a card with a connector you cannot wire to standard drivers.
Now, let's trace the "work" from start to finish. This is the practical answer to "how does it work?" Motion planner / controller software
