Description of XHC MK4 Mach3 USB Motion Control Card:
This is the latest generation 3 Axis motion control card, which is the fourth generation calling MK3-IV. The maximum
step-pulse frequency is 2000 kHz ( The last generation MK3-III is 400KHz). Now MK3-IV is stronger,
more stable and better performance.
Features of XHC MK4 Mach3 USB Motion Control Card:
1.Dual-Processors, ARM+FPGA, More processing power
2. Support all versions of Mach3 (can’t work with Mach4).
3.Work under Windows 32-bit operating system (not including Mac OS)
4.USB jack does not need to install the driver, plug and play under all versions of Windows.
5.Full support USB hot-swappable, USB connection status monitoring at any time. Under Mach3 working state, USB cable unplugs and then plugs in, but also the normal connection.
6.Supports3-axis linkage.
7. Maximum step-pulse frequency is 2 MHz, can connect servo driver/stepper, driver.
8. The indicator light indicates various working status, such as USB connection, Mach3 connection and so on.
9.16 inputs.
10. Onboard isolated power supply, not need an external power supply.
11.All IO port fully isolated, strong anti-interference, stable performance.
12.Support spindle speed PWM output; support spindle pulse and direction output; support spindle speed output from 0 to 10V analog voltage.
13.Support XHC series of wireless electronic mach3 MPG, such as whb04 mpg.
14. With an aluminum shell, effectively shielding interference, stable and reliable performance.
