  1. Re: ACER WITH NO SPINDLE GEARS: VFD OR 3KW SERVO?

    Mac,
    So motor is good, and v/f mode seems to work okay. I looked into inverter motors and they might be a future investment. Wondering why svl mode didn't work.

    Thanks for the tips!

  2. Re: ACER WITH NO SPINDLE GEARS: VFD OR 3KW SERVO?

    Thanks Mac,
    I've talked to a few more people today and I've a feeling that might be what happened. I have not been back to the shop but I'll test the motor straight to the 3 phase first thing....
  3. Re: ACER WITH NO SPINDLE GEARS: VFD OR 3KW SERVO?

    Jim, Skrubol,
    Thanks for you replies, I stalled on a 1/2'' rougher in aluminum block, obviously something was wrong.
    I took Jim's idea and ran with it: After finding I nuked my VFD by power...
  4. Re: KANALOG TO MACH3: FRO POT, MPG, Z encoder INPUT AND CODING

    Thanks Tom,
    I'll experiment with the example codes and ADC inputs.
  5. Re: KANALOG TO MACH3: FRO POT, MPG, Z encoder INPUT AND CODING

    Okay, Thanks guys. I'll give Kmotion closer look.
    Still wondering where I can input these devices? And what bits to access them on Kanalog. JP6.

    Thanks
  6. KANALOG TO MACH3: FRO POT, MPG, Z encoder INPUT AND CODING

    Hello all,
    So i've retrofitted a old acer mill and built a pendent to control, using mach3 and Kflop/Kanalog.
    I'm not familiar with C programming so I've gotten myself in a pickle with Kflop so...
  7. Re: ACER WITH NO SPINDLE GEARS: VFD OR 3KW SERVO?

    That is great to hear, but what worries me is that I'm pretty sure I did do that when setting up the VFD. The pully ratio doesn't help but I'll check it again. What size pullys are you using?
    ...
  8. Re: ACER WITH NO SPINDLE GEARS: VFD OR 3KW SERVO?

    Thanks, that helps. I was worried about the pulley ratio, seemed too much. I looked around and seems my VFD is capable of vector mode, but double check me:

    Re: Dynamotion > Mach3 Defining Axes

    There's got to be a ground in there some where right? So 5v to switch, to input, to ground. Current flow when the switch is closed, driving the input high. 10k ohm between the switch and ground to...

    Re: Dynamotion > Mach3 Defining Axes

    Actively driven as in current from the 5 volt source to the input when the switch is closed, and pulled low with a resistor when open. J7 inputs have internal resistors.

    Are the inputs on the KFLOP sinking or sourcing?

    Re: Dynamotion > Mach3 Defining Axes

    So I have J7 pins 0-7 to Normally closed limit switchs, from j7 5v back to the 0-7 pins. And I dont see where the copy to c program sets them as inputs.

    I have my limit switches on pins 0-7, but they seem to be floating in my Digital I/O screen, and I'm not seeing any C commands setting them at inputs, except...

    Re: Dynamotion > Mach3 Defining Axes

    So all Axis move both directions when commanded by Kflop console. It's something in the C file between Kflop and MACH3.

    Thanks, for you help All.

    MC,
    You were correct. I changed the output channels to corresponding axis and Mach3 responded.
    Any idea why my axis only move in 1 direction? Must have been something I might have deleted in the .c...

    Re: Dynamotion > Mach3 Defining Axes

    So I'm defiantly using open collector mode, but I'm not clear on how you associated j7 19/20 with generator 2.

    Right, So I already have the relays. I just need to know now to implement the code with the pins.

    Re: KFLOP SETUP, CHANNELS AND PINS

    So the spindle just needs a switch to close, same thing with the air solenoid relay. I just need to know how to wire the pins to the fkop, find the code and implement it into the board.

    Thanks
