    Default 6 axis breakout board

    Hi guys i need some input please. A good few months ago i decided to do a complete rebuild of my cnc router. I've decided to use a breakout board that i bought last year on a wim. The rason for this is that it has 0-10v pwm control which will allow me to control my spindle from linuxcnc. The problem i have is that i never had any real instructions for it hence why it was never used. I think the connections in the main are self explanatory but i do question some of the translation.

    here is the beast and instructions, i removed the pic of the board from the doc so i could upload it but it was the same as the separate pic anyway without the labels. The areas that confuse me a bit are what they call common cathode and and common anode? do they really mean that? note that there are 3 connections for each of the relays.

    My machine is a 3 axis router with duel screws (X and A), i'm using typical 4.5 amp steppers so no surprises there for wiring. So my questions are what connections do i need to connect to the VR, VI, ACM and relay for my hauyang VFD. Any comments around any connections made to it would be really appreciated.

    Thanks

    Paul

    Ok here is my thinking so far please correct me if you think i'm wrong here.

    Driver to use for each axis is an M542-G, the USB connector will be connec ted to a 5v supply. 24v and GND on the left of the BOB will be connected to a separate 24v supply.

    P1 = X axis Step +
    P2 = X axis Dir +
    P3 = Y axis Step +
    P4 = Y axis Dir +
    P5 = Z axis Step +
    P6 = Z axis Dir +
    P7 = A axis Step + (second screw of X axis)
    P8 = A axis Dir + (second screw of X axis)
    P9 = ENA +
    All the above connect ' - ' to a 'Common Cathode'

    Spindle:

    This is difficult as interpretation of instructions is really bad but my guess is?

    Analog Signal 0-10v = VR + on VFD (right hand side connections along the bottom of the bob)
    Power GND = ACM on VFD (right hand side connections along the bottom of the bob)

    Select the first connection of a relay = FOR on VFD
    Select the second connection of the relay = DCM on VFD

    What do i connect VI to?

    Is there anybody that can read chinese that could attempt to translate what is seen on the board please.

    Thanks to anybody that will even just give an opinion on this.

    Is there anybody else using this BOB?

    Think i have worked out the relay connections.

    In order the three connections are

    NO - Volt In - NC

    Buzzing out the board i have worked out that relays corrospond to the following pins:

    Relay 1 = Pin 14
    Relay 2 = Pin 16
    Relay 3 = Pin 17

    You can disable the relays from these pins by removing the jumpers located above pin 4 on the board

    Can you post some pics of what you need translated?
    And a pic of the board?

    I've posted a few times and had hit or miss responses / feedback so I know how aggravating it can be. I don't speak Chinese but have several friends there and may be able to get help from them with the translation.

    I am going through a setup revision on my mill and worked through getting the VFD installed and setup in Mach3; mostly that was ports & pins setup on the input to the BOB, not so much the outputs from the BOB.

    Hi Dstamp thanks for coming back to me. I think i am sorted with the translation now through staring and staring at the pics and running through the circuit. the only thing in Chinese is the ports maked up as Anode and Cathode which i understand now, so no problem there. The only issue i really have left is where i should connect the 'VI' port on the VFD to. I should be left with two pins for the other relays which i will use to turn on the VAC and Cooling for the spindle.

    Once i can connect and test all the ports i will make sure i post a proper pinout with explanation for everybody. In general this is a well buit and layed out board, only the instructions let it down. I will wire it up only connecting my digital meter later today and run through testing everything.

    Just relised a mistake (too comfortable using different drivers). All the axis will connect to a common Anode as that is what the M542 drivers require. Individual ' - ' connections will be swaped over with the ' + ' ones. Still stumped on what i should connect to the 'VI' port on the VFD, any help with is still needed please.

    What VFD do you have?
    I might be in the same boat as you, while I'm trying to wire my 1.5kW VFD and watercooled spindle through my G540 to control through Mach3.
