    Did you measure fingers/position on other holders and compare to problematic one?

    How soon into the program?
    Can you dry run starting just before the bad tool change and [slow-motion] video it?

    HCs are usually 1HP or 1.5HP.

    If one were to gut most of the electrical cabinet to VFD retrofit (there are web/PM articles on this), I might consider pulling the old motor and driving with a...

    So the seller also has a Haas 5C indexer with the controller and it interfaces and works with the VMC as an indexer using M codes.

    They are asking $2500 for it and I donít have that right now as...

    His Hardinge HC almost certainly wonít work by hooking the output from a VFD as the input of the lathe.
    Hardinge electrical cabinets have all sorts of circuits that are not motors.

  9. Connecting single phase to a VFD designed for 3-phase input

    I would be surprised if it mattered which input legs you use since they are symmetrical. Itís all rectified to DC anyways

    #2 is a good point.

    Congratulations!
    Chuckers are great machines, especially if youíre doing production. You can think of them almost as hand-cranked predecessors to CNC lathes.
    They arenít really general purpose...

    Oh yeah!
    I saw 3.6V and my mind somehow added .1V to make it 3.7V and I thought lithium ion.

    Well, I have plenty of NiMH batteries and packs, so easy to make an external pack with higher...

  18. Backing up Mitsubishi Meldas Control Parameters, Ladder, ...?

    SRT Mike very helpfully posted this detailed response (Thanks!!) in my other thread, but I thought it might be useful to split it off for future reference/web searches.
    Can someone confirm...

    Right.
    I meant smaller than 100HP :-)
    I didnít look at the startup current when we were soft starting (it was a long ramp up), but letís assume it was no more than 20A (or we would have had a very...

    We have FLIRs at work, but donít think I can take them home.

    VFD was 400-500V input.

    In theory, we were already over the insulation rated voltage (300V, I think) for the cord already.
    In reality, Iím sure it would hipot test probably over 600V anyways. ...

    You could definitely use a smaller VFD to spin it up.
    Youíll only be able to generate whatever power your supply line current will give you, minus idling power and other losses.
