With Ni PXI-7340 (part numbers: 779036-02 and 77935-01) motion controller, users can use synchronous and coordinated motion control of up to four axes under preemptive, multi-task and constant conditions. This model provides an advanced dual-processor architecture, using 32-bit CPU combined with digital signal processor (DSP) and custom FPGAs to realize this super power of motion controller. The FIFO interface and dense capacity set provide fast communication, and at the same time, the complex motion capacity is offloaded from the host PC to optimize the execution of the framework. This nickel PXI-7340 motion controller uses DSP for all closed-loop control, including position tracking, PID closed-loop control calculation and motion trajectory generation. The DSP is supported by custom FPGAs, and performs fast encoder interface, position capture and breakpoint functions, motion I/O processing and step pulse generation to realize hard real-time functions. In this model, the inserted CPU runs to a multi-task and constant working framework, and handles host communication, command processing, multi-axis interpolation, error handling, general digital I/O and the integrated capability of the whole moving framework. Embedded firmware depends on the installed RTOS devices, and provides ideal framework implementation in different sports applications. The task is organized. The execution sequence of tasks depends on the needs of each task, the conditions of the whole motion frame, I/O or other frame events, and the real-time clock. This nickel PXI-7340 motion controller direction generator calculates the fast position charge, and when it moves the hub to the target position, the fast position charge controls the increasing speed and speed. According to how the user designs the hub, this command is then sent to the PID servo loop or stepping beat generator.
