    Re: 110v VFD's. Any issues?

    On 120V supply you have to have a minimum of 20A to run a 1.5Kw Spindle 25A would be better, so your normal 120v outlet is only 15A so you are not going to successfully run even a 1.5Kw Spindle on it...

    Re: Usability of Encoder on DC Motor,

    There is nothing to fix

    Acorn does not have a problem with anything to do with Encoder input, the Encoder only needs to be on the spindle it can of cause be on both but is not needed unless you...
  8. Re: Chinese 2.2kw water cooled spindle not turning when starting

    So you have not connected the Ground 4th Pin in your spindle, if you have to spin it by hand to start it is missing a Phase either wiring, or a problem with the spindle / VFD check the continuity of...

    Re: Chinese 2.2kw spindle burned out?

    The Drive faults with a load Spindle attached, so if he removes the Spindle the drive will output when turned on and then can be measured at U V W

    Re: Chinese 2.2kw spindle burned out?

    Not successfully without problems, 50Hz and 60Hz motors yes it is possible but not 400Hz Spindles



    Your over current problem is a missing Phase from a damaged VFD Drive IGBT or Zener Diode,...

    Re: Usability of Encoder on DC Motor,

    If you are only working at Hobby level then anything can work even just a single index pulse, it just the control he is using has a requirement which has to be met or it will not work

    Re: Usability of Encoder on DC Motor,

    Re: Chinese 2.2kw spindle burned out?

    That Braiding does not work and can not be used for your installation, it could make it worse, if your correct cable cost $100 I would be surprised, most is normally around $60

    I'm not sure what your point is his Control has a requirement, and a low count Encoder like you describe is a waste of time, for anything to do with machining, the more PPR the reaction and...

    Re: Usability of Encoder on DC Motor,

    Re: Chinese 2.2kw spindle burned out?

    You need to check the Parameters are correct

    This can mean more than one thing, this is ( 1 ) to try increase PD014=8 and see if it can get up to speed if not then it has a Phase problem

    It sounds like you are almost there

    You don't want anything to do with the Bob and Mains Power Grounding
