Description LF77-AKZ250-USB3-NPN(B) Mach3 USB Interface Board 5-Axis CNC Controller Board Motion Controller for CNC Engraving MachinesFeatures:- It has a USB interface and no driver is required.- Support 5-axis linkage, 500KHz output at the same time, connected to servo/stepping. Any one axis can be configured as a pulse spindle.- 2 real-time electronic handwheel (MPG) input ports, which can connect 2 electronic handwheels at the same time. When the MACH3 electronic handwheel is set in Multi-Step mode, it has the same real-time performance as the CNC machining center, and runs smoothly. There is no delay in the control board, and the performance of the mechanical system is fully utilized.- With real-time jog, there is no delay in the control panel, the motor responds quickly and quickly, and the experience is zero delay.- 16 general digital input points, corresponding to 16 LED indicators. Customize the configuration function in MACH3. Support Mach3 spindle speed measurement function.- 7 general-purpose digital output points, configurable as: spindle start/stop/coolant/custom M code VBasic programming control- 1 PWM output point for analog spindle speed control: pulse width speed control / 0-10V inverter speed control.- 2 analog inputs, used to adjust the processing speed / jog speed / spindle speed.- 1 status indicator, which can indicate the USB connection, and the status of the motor is clear at a glance.- Using 5 dual-channel 10Mhz high-speed optocouplers, 25 general optocouplers, a total of 30 optocouplers, isolate all input/output. The high-cost design provides complete anti-interference performance and complete safety protection.- Without PC intervention, the signal is processed independently by the motion control board to ensure that you have real real-time and reliability.- Support all versions of Mach3. Supports all versions (32-bit/64-bit). For Windows XP to Windows 10, and all Windows versions are plug and play.- The chip firmware supports upgrades, and users can continuously get the latest function support.- Provide a complete installation manual with clear documentation, illustrations and detailed descriptions.- 16 input/7 output/5 axis/spindle speed control signals are all optically coupled and electrically isolated. Highly safe and reliable design.- Environmentally-Friendly Copper Terminals: Axis output x 5 / general output x 7 / (0-10V) output x 1 / (0-5V) output x 1 / PWM output x1 / general NPN input x16 / power input- Copper USB Socket:- 5-axis output signal (direction signal + pulse signal): 10MHz high-speed optocoupler isolation x 10 channels- Optocoupler isolation PWM spindle speed control signal output x 1 / Optocoupler isolation general output x 7- 8-channel output driver chip, using high-quality round pin sockets, convenient for users to replace the chip- Optocoupler isolated NPN input x16 / power input- 2 groups of power supplies: BUCK switching power supply + LDO low dropout linear power supply- Tantalum capacitor + self-recovery fuse + anti-reverse diode + TVS anti-surge diode- USB cable (Accessory: USB cable x 1.5M, 7mm magnetic ring x 2)- External magnification knob- Wiring of Controller Board & Laptop- Schematic Diagram: USB main control chip + external magnification knob x 2- 10MHz high-speed optocoupler isolation x 10 channels + optocoupler isolation PWM spindle speed control signal output x1- Optocoupler isolation NPN input x 16 + Optocoupler isolation general output x 7- DCDC Power Supply + LDO Power Supply- Download information:http://leafboy77.com/http://leafboy77.com/files/usb_eth_edg381/Mach3_USB_Motion_Board_AKZ250V3_NPN(B)_Manual.ziphttp://leafboy77.com/files/usb_eth_edg381/eMotionMach3.ziphttp://www.machsupport.com/software/mach3/ Package Included:- 1 x Controller Board Payment Terms 1.
