Mach3 USB Motion Board AKZ250V3 NPN[ENGLISH]

MODEL:LF77-AKZ250-USB3-NPN-3AXIS

MODEL:LF77-AKZ250-USB3-NPN-5AXIS

THIS is a 3/5 axis Mach3 USB interface board(NPN) worked with Mach3.

Download: Installation Manual, Plugin, Schematic

Features:

USB Full-speed connection.

Up to 5 axes, 500kHz pulsing engine, which is suitable for the servo or stepping motor. Any axis can be configured as a Step/Dir Spindle.

Support slave axis (dual side motor drive: dual X/Y/Z), support home automatic leveling (dual side home switch).

2 real-time Manual Pulse Generation(MPG) input ports for 2 MPG at the same time. When the MACH3 MPG is set in the multi-step mode, it has the same real-time performance as the CNC machining center, smoothly. The control board has no delay and the mechanical system performance is fully utilized.

16 general-purpose input, with particular indicators, the input signal states can clearly shows.

 8 general-purpose output, It can be configured as: spindle clockwise / CCW / Mist / Flood / VB script programming control.

PWM signal spindle control or Step/Dir signal spindle control.

2 analog input ports for adjusting the machining speed / jog speed / spindle speed.

Status indicator LED can be useful to show the USB connection, and working stauts by flashing.

5 high-speed optocouplers(Dual Channel) with 10MHz, 28 general optocouplers for isolating all of the input/output signals, this high-cost design can be provided high performance and stable system.

Fully supporting all Mach3 versions. Supporting Windows series, including Windows XP-Windows10(32bit/64bit).

No need to install any USB drivers, it can be used after plugging in the computer.

Easy firmware update.

Provide a complete installation manual, illustrated, detailed description.

ChangeLog:

V2.0.0.0 Add: Slave Axis, Axis Link, Home Limit, Pulse(Step/Dir) Spindle

V1.3.1.2 Add function: “MPG Enable Button” automatically switch JOG mode. (For details, please refer to the Revisions List in the manual)

V1.3.1.1 Fix bug: G31 (for Auto Tool Zero, etc… ) cannot be executed correctly.

V1.3.0.2 Fix bug: The displayed value(RPM) of the speed measurement is twice as high as the actual speed.

V1.3.0.1 Fix bug: The G code execution line number is incorrect after the RESET(urgency-stop)

V1.2.1.0 Fix bug G31″Auto Tool Zero”
