    Default Journeyman 325 Spindle to VFD

    Hello,

    I need some assistance in trouble shooting my Journeyman 325 main spindle conversion to VFD.

    I have a:

    Yaskawa UAASKA-04CA1 Spindle Motor
    3phase 200V 3.7/2.2 KW

    Automation Direct
    GS23-2010 AC general purpose VFD drive.
    https://www.automationdirect.com/adc...pose/gs23-2010

    Continuity between U+V, U+W, V+W is fine.
    Ohm readings between U+V, U+W, V+W all read the same
    Nothing is shorted to ground.

    I changed the parameters on the VFD via USB to match the motors current rating and voltage.

    I can get the spindle to start but once It gets up around 100rpm's it starts to draw about 60+ amps then shortly overloads the VFD.

    Let me know if anyone need photos or anymore information to help me diagnose this problem.

    Thanks.

    What do you have for the speed and frequency settings in the vfd?

    Please post a photo of the motor nameplate.

    ...if this is the Manual for your Model VFD
    https://cdn.automationdirect.com/sta.../gs20m/ch4.pdf

    Try setting P01.44 to 3 for Auto ACC/DEC

    You need to set the max speed to 8000 rpm, like the nameplate says. And the max frequency needs to be correct, too. 267hz, if I recall correctly. Also make sure voltage is set to 200v. Nothing higher.

    All,

    Thanks for all the help Changing the settings to:
    * Max RPM to 8000
    * Max FQ 267
    * Max V 200
    * P01.44 to 3 (Auto ACC/DEC)

    Worked like a charm. now just need to get it to "talk" to the Dynapath Delta 20M (See link below) for my other forum post.
