    Default 3Kw 220V spindle issues.

    I have a spindle that has been working until today. The spindle will start when I hit the spindle control in Mach3 and then (not immediately) shut down. I get an HoC code on the front of the VFD. I removed the wire connection to the top of the spindle and ran the spindle with Mach3 again. I can get it up to 400 and back down without any code. I assume this means that my spindle is bad but why would it startup in the first place.

    Can anyone tell me if the spindle is truly bad and if I need to replace or is it something else?

    I tried everything to post the video but I was unable. So here is a link to the video

    Find your manual and look up the code that is displayed. If you have to spin it to start you might have a missing phase connection either in the motor or drive wiring to the motor.

    Never depend on checking from a VFD output to ground as it needs to be phase to phase check.

    What VFD Drive do you have model number and brand name

    This can be many different problems as the spindle did not reach max speed, increase the ramp up to speed time Parameter

    No, I don't have to spin it to start, that was to just show it spins freely.

    Ok check P038 and see what you have this may be set to low

    P038=

    Because you have been running for some time first check the spindle with a meter

    From the spindle plug

    Pin 1 to Pin 2=

    Pin 2 to Pin 3=

    Pin 3 to Pin 1=

    Pin 4 to spindle Body ( this is Ground )

    And all Pins to the Spindle Body

    Then check the Cable from the VFD Drive to the Spindle, and inside the plug connections

    Why do you have to check this, this Fault indicates that there could be a short in your wiring or your Spindle

    Who made up the cable from the VFD output to the spindle and plug? Very possible you have a loose or broken connection. Or the wires inside the cable end plug are shorted or open.

    The company made the cable. I have asked the company for a manual and the parameters for the VFD but they have not responded. I'm not sure how to work the VFD but did put in P038 and pushed the button and it shows a 6.0. Would that be a correct number? I will check for a short between the wires today and post the results.
    Thanks for the help and direction

    I just checked the wires on the spindle side and the plug side and there were no shorts. The ground pin was shorted to the case on the spindle side but that was it.

    between all of the pins read 0.8 ohms and nothing or open between the ground pin and others.
