    Hi,

    I've had a extra look.

    The only cabels that is going in and out of the controlbox is:

    In: main power

    Out: Cabels to the motor, emergency stop, cabels to the display for fine feed of spindle sleve

    There is no general purpose connector or similar.

    The X connections are marked on the bord, some are almost not visable anymore. Se pics of X3, X6 and X7

    I've taken a pic of the back of the LCD-display


    I should be thanking you for you're patience!

    Best Regards

    So controlling spindle operation will be doable via analysis of your reversing switch.

    This switch will most likely have a voltage or ground that is switched when you turn it. This will be hooked to relays used to control spindle direction. You may need a third relay to do spindle on-off.

    The other part of it is that potentiometer. You should check what’s it’s input voltage is and what happens when you turn it. It may be possible to use a PWM spindle controller hooked to that switch to change the speed.

    Also a point of annoyance - your controller may closed loop operation. Or the encoder may only drive the LCD.

    The mechanism I use does not support closed loop - and you cannot do closed loop straight off of the UC100 unit with the encoder feedback. That means no rigid tapping. Only the UC300 is powerful enough.
