    Straight from Bob Campbell:
    Try this. Make sure that the jumper JP1 is on both pins. Jp1 jumper makes a connection between the NO connection on the run relay to the center screw terminal on the dir relay.
    For the connection to the VFD run a wire from the center screw terminal on the run relay to the common pin 11 on the VFD. Then run a wire from NC screw terminal on the Dir relay to terminal 1 on the VFD. Then run a wire from the NO screw terminal on the Dir relay to terminal 2 on the VFD.

    I think the fog is clearing, a little.
    Thanks

    To me, unless you have a Stop connection the VFD will always be in run?
    Unless we are not getting the full picture on the VFD?
    The contact is labelled RUN/Stop which implies that you open it to stop?

    I checked the manual, the connection you mentioned is for 3 wire control, only fwd OR rev, unless you add a relay.
    To get Fwd and rev then you need another relay or a switch.
    Your picture shows the two wire control.
    The bottom line is it appears whichever method you use the VFD in, you need two relays, if you need both FWD & REV.

    On the bob are 4 relays.1 for the charge pump /estop, 1 for coolant or what ever and 2 you can setup for the spindle.
    It is all very clear in the Campbell manual.Any way long and short.
    If you go to the ports pin config and select spindle,enter 1 and 2 for output numbers.Enter m03 in mdi or press spindle start and one of the relays will click closed.press stop and it will release.m04 and it will close the relay.
    Now just connect the n/o contacts to 1 and 11 on the vfd.This will start the motor forward.When the other relay is connected n/o to 2 and 11 the spindle
    will reverse.The 0-10 v analog signal from the bob is connected to the
    0-10 vdc input on the vfd.The bob has to be set up as per the instuctions in the manual.For coolant just unclick the disable flood/mist relays and set them both to output 3 or both 4 ,now click on coolant or m08 on the mdi and
    the 3 relay should click in.

    VFD died yesterday before I had a chance to do any wiring. Went to check some voltages, just to satisfy my own curiosity, and the display said "sc short circuit". I called Yaskawa and they had me unplug the motor leads. Nothing. They will rebuild it for $751, but will look at it for free. It was about a '87 model as close as I could figure.
    Sooo,
    I need a vfd for a 3hp 3phase 220v motor that uses a 0-10v control system. Or are they all that 0-10 system.

    Most have a couple or more of command options with 0-10v being a common one.
    I usually look for Mitsubishi or Telemecanique-Altivar or WEG on Ebay, some list less the programming unit if it is not built in, so this would have to be purchased if not included.

    Thanks Al.
    I was just looking on Ebay. Plenty to chose from.

    Any new info? Somebody give me a pic or something, I need a fix.


    I have my Hurco back working again, but I want to take pics and maybe sell the parts out of it before it breaks down again. That way I can prove the parts were working when I stripped it.

    I keep reading the retro-fit threads to keep me motivated.

    From what I have read, Vipers are the only way to go.

    From what I have read, others opinions are:

    The other company's are hard to get in touch with for support, or to even purchase from sometimes.

    Gecko's don't have enough voltage, and are hard to check with the covers on.

    Larry is very helpful, he even calls people to see if they got everything worked out.

    The Viper manual compared to the others is pretty easy to understand ( although I don't have a controller in front of me right now that I am trying to trouble shoot), it doesn't look intimidating.

    IR, give me an update on this. I'm just checking to see where you are. Did you get a new inverter, yet?

    No vfd yet. Had to take some time off to do the summer family vacation thing. Larry fixed my screwup for the price of shipping!!! He has my business!
    I see alot of those Telemecanique vfd on ebay that are reconditioned, but I think I'll get a new one.
    There are alot of places that fix vfds. I may send the old one out, later.
    I'm currently haveing the terrible urge to re-wire the entire control into one box like Kieth did. It would sure tidy things up.
    I'm going to go power up the old vfd one more time.
    I'll get some pics.
    I hadn't thought of it, but I guess I'll post an ad on ebay for the old drives. Someone may need them.
    have fun

    I looked up the wiring diagram for my npn z axis. It has a BK-------+V, and a BU--------0V. On my switch I have black, blue and brown wires. On the board it has +12v,Sig,and grd.
    Which goes where?
    Also, my limit switches break the circuit when they come into contact with the stops. How do I wire this on the combo board?
    Thanks

    Larry,
    I have the boards in and am tuning the motors. The yellow warning light stays on. There is only one POT now that effects the red warning light. How do I adjust the setting for yellow?
    thanks

    IT LIVES!!!!
    X and Z move and repeat within .002". Fixed that with backlash. Y encoder seems to be shot, it will not repeat and seems to make random moves. Will buy a new one in the am. I'll write more about this later.
    It is a thrill when you see the thing obeying commands!
    have fun

    I'm no help, but this in interesting reading.

    A man can't work for free or give away his work, but when I hear about things like:

    Larry fixed my screwup for the price of shipping!!!
    That make me appreciate that person more. I would never say "Hey Larry, fix mine for free like you did for I_R_" But if Larry wanted to, that is his option.
    Maybe it took a $.05 part to fix your driver and I messed up a $75 part.

    He has proven himself, and when he told of going to that guys shop ( In Canada) that retro'd the Hurco. That was beyond the call of duty.

    Maybe I'll start on mine in another month or 2.

    In the days of expected poor customer service, it is really refreshing to come across someone who stands behind thier products like Larry. Bob Campbell also has provided me with exceptional support. I hope that my misadventures here will inspire others to buy these products and put money in the pockets of those that have helped me.
    I haven't finished this retrofit and am already looking for the next one.
    have fun

    I made a change that gives the drive Low_voltage detection. The yellow led is now "Main power on". Also it does a soft start when main power is turned on. (I used the current warning chanel for this mod so there is only 1 pot now).
    My next gen Vipers will have this built in.

    Encoder Madness!
    I know I want a differential encoder, but do I want an incremental or absolute? Unidirectional or bidirectional? Index or No index?

    thanks

    If your system accepts differential this is the preferred way for noise rejection, these are incremental, RS485.
    http://focus.tij.co.jp/jp/lit/an/slla143/slla143.pdf
    Very few system use absolute, Robots are the exception where absolute is used extensively.
    If you use a system/drives etc that does not use a marker for homing, then you will probably not have any use for it.
    Differential encoders are by nature, Bi-directional.
    Come to that, so are absolute?

    Just ordered the Teco CV7300 vfd. Probably more than I need but what the hey.
    Now on to the encoder hunt!!!

    I've found a 2500 count differential encoder on automationdirect.com. All I can see of the name is CE. The number is trd-sh2500-vd.
    Will I cause myself problems if I have encoders with different counts on them? 1000 on one axis and 2500 on the other?
    Should I get a more expensive encoder?
    thanks

    As a general rule, it does not matter as the encoder is scaled by the controller it is input to.
    Is this a single ended type or differential?
    As the VD may imply single ended?
