3) 16 ports photoelectric isolated output interface;
4) 1 port 0-10V spindle speed analog output interface(can change to PWM output);
5) can support 6 axis stepper systems maxisim, 125KHz pulse output for every axis;
6) ARM motion control chip;
7) Main device is 12V-32VDC power supply input,current should higher than 1A;
2.Product connection define and method
The connection of the controller includes power supply interface, USB connection interface, Stepper/Servo control output interface, spindle control output interface, Estop and limited switch and tool setting input interface and so on. Now we descript them in details as below.
2.1 USB Port
Marked NO1 position is the USB port, Mach3 connect to this board through the USB port.
2.2 Main Power Input
No.1 terminal block is main power input interface, need input 12-40V/above 20W. There is a silkprint “+” and “-“, see in the picture, left terminal is
“+” and the right terminal is “-“.
“+” and the right terminal is “-“.
2.3 Limit/Home/Estop/Probe input port
Marked No.3 position is the input port, they are the optical isolated Input interface. The silkprint INP1, INP2, GND, INP3, INP4, INP5, INP6, INP7, INP8, INP9, GND, IN10, IN11, IN12, IN13, IN14, IN15, IN16, GND, 12V on the board connect to the PIN1-16 of the mach3.
2.4 Serial expansion interface
Marked No.4 position is serial expansion interface, we can extend some other equipment from this interface. Definition of port is RXD, TXD, GND from left to right.
2.5 MPG port
Marked No.5 postion interface is MPG port.
2.6 Universal output interface 2
Marked No.6 is universal output interface 2, this port type is DB15, OUT5-OUT16 are fixed on this port.
3. Stepper motor control interface
The marked No.8 are 6 axis stepper motor controller port, they are X/Y/Z/A/B/C from left to right, Each axis’s pin is defined as COM+/CP-/DIR- from left to right, Wiring method see as bellows:
4. Spindle control output
We define the interface from left are: GND1(Output GND),VSO(0-10V adjustable speed output),OT1, OT2, OT3, OT4.
Take Nowforeuer inverter as the example. Spindle control output and the inverter connection showed as bellow picture and DCM are closed,only need to connect one port.
