    Default New member - Spindle setup Optimum BF 46 with UCCNC

    Hello,

    I'm a new member and i hope someone could help me or point me i the right direction.

    I recently bought a used Optimum BF 46 Vario from 2007 fitted with stepper motors from optimum controlled by optimum controller IV.

    I use UCCNC together with UC100 motion controller and Fusion 360 for CAD/CAM.

    I´ve got the x,y,z axis to work but i don´t know how to connect the spindle to the controller IV and setup with UCCNC or if even is possible.

    Is there anyone here with a Optimum mill that uses Controller IV or anyone who got a good guess.

    Info on the optimum controller IV:

    The Unit has:
    1 X parallel ports named port 1 (25pin)
    9 pin connection plug for a three axis point of origin
    4 X slots for the stepper motor cards (I am using 3)
    1 X relay port, potetial free relay output (8 outputs/pins)

    Pin assignments for the DB 25 male is
    Pin Application Description
    1 RELAY Switch output eg (motor on)
    2 Direction X axis
    3 Cycle X axis
    4 Direction Y axis
    5 Cycle Y axis
    6 Direction Z axis
    7 Cycle Z axis
    8 4th Axis
    9 4th Axis
    10 Free
    11 References switch Z
    12 References switch Y
    13 References switch X
    14 RELAY Output eg coolant
    15 Reference switch 4th axis
    16 - 24 Free
    25 OV DC, Earthing

    The 9 pin connection pins are as follows for the reference switches
    1 X1 Machine point of origin port 1 X Axis
    2 Y1 Machine point of origin port 1 Y Axis
    3 Z1 Machine point of origin port 1 Z Axis
    4 ROUND TABLE
    5 +12V DC
    6 X2 Machine point of origin port 2 X Axis
    7 Y2 Machine point of origin port 2 Y Axis
    8 Z2 Machine point of origin port 2 Z Axis
    9 OV DC


    I would like to controll the spindle speed, direction and on/off from within UCCNC.


    Greetings from Sweden.

    So i do this with the c76 board from cnc4pc. But on a KBIC controller. On a g0704.

    Chances are high that you have a KBIC clone controller inside the spindle control box.

    If so, yes you can control spindle speed this way. I chose only a forward direction but it may be doable to do both. Please advise if a KBIC controller is inside your motor box.

    Hi,

    Thanks for the response.

    How do i know if i have a KBIC clone controller?

    Best Regards

    KBIC-125 (9433) DC Drives Chassis https://www.amazon.com/dp/B007ZQLJM0..._6P3VCbMZS9BBP

    It will look like this for the most part. Hear sink for the mosfets and this mounting pattern. Take a pic and post it please.

    That is much fancier than a KBIC. It probably has an integrated LCD for spindle speed.

    Is optimum still in business? And any chance you can find a part number on this board?

    I’m guessing the thick wires on the left go to the motor, and that it is a 4 conductor motor?

    Yes it has a display for spindle speed, Optimum is still in business but are not very helpful (dosen't answer).

    Yes i got a hold of a manual and the Part nr is 03021303201

    I also got a hold of the wiring diagram. se pic

    I took a pic of the motorplate.

    Best Regards

    I'm sorry i wrote Controller VI but it is the VI i've got.

    Thanks anyway.

    Interesting. That is a 2.2KW closed loop BLDC drive.

    X3 is motor drive power.

    X7 is the hall effect sensor for the motor.

    Are the X* connections marked on the main board?

    It says X6 is going to a 12 pin or more connector - would that be the bundle of pink wires?

    And does the motor control box have a general purpose connector on it anywhere? One that goes back to Controller VI?

    Okey,

    I don't think the X connections are marked, but i will have a look tomorrow.

    Yes X6 is most likely the bundle of pink wires, i'm attaching two pics.

    I'm pretty sure that the motor controllbox doesen't have a general purpose connector on it, I will have a extra look tomorrow.

    The only cabel that goes from the motor controlbox to the Controller VI is the emergency stop (the grey cable)

    I guess it's via the relay outputs on the controller VI i should controll the spindle (No 7 in the picture of the controller)

    So here is my analysis of whats going on so far:

    1. Your Controller VI may not control the spindle at all. Nothing. It may only want to control the axis motion.

    2. You have a standard on/off switch, estop mechanism as well. We can ignore these for now.

    3. You will need to figure out exactly what your reversing switch does. Does it send a control signal to the board saying "forward/rearward motion" or does it actually swap the polarity on the motor inputs. Seems like it might be control signals based on how the motor is wired up. You should look up its part number if you can find it, and check its behavior with a meter to see what it does.

    4. The hardest thing will be dealing with the potentiometer that controls spindle speed. It may have its resistance measured by the RPM display board and send a digital signal back to the controller to adjust the spindle speed.

    Can you send a picture of the back of the RPM display?

    Thanks for your patience.
