The PWM speed-regulating output port (isolated) can set the PWM frequency and the duty ratio of 0-1000 is continuously adjustable. Support All Mach3 versions, including the latest version Input and output, super reliability, absolutely ensure the safety of computer USB. At the same time ensure the super EMC anti-interference ability. Support all Windows versions, including Win8 WIN10 The motion control buffer size can be set, the fastest interpolation period can be guaranteed to be stable, and the computer can operate stably even when the running load of the computer is overweight. USB doesn't require a driver, all Windows versions plug and play, support hot plug Single chip, the system is more refined, and is more stable than the general multi-chip processing method. USB bus user high-grade chip magnetic coupling isolation, really valuable isolation With the function of speed measurement, the actual speed of the main shaft is displayed in real time in the Mach3 interface, and the measurement is accurate and stable
