    You have to pull the "fan" off the back end, and then there should be a LH nut under it that needs to be removed. Then it will all come apart.

    How do we know if the preload is correct?

    Assume that's it's probably not. I have two, and they are noticeably different.
    The proper method of preloading is with matched, ground bearings, which cost more than the spindle.

    Hi, I've uploaded a youtube video of the motor in action including throwing the error code.

    The motor is making sort of a grinding noise when it runs seems like as compared to near silent running when it was new.

    I've checked the drive settings and things looked normal,
    50 hz,
    220 v,
    3 second ramp up
    3 second ramp down



    Thanks for everyones help so far?

    Electrical code does matter, however codes are so strict around here that in this small garage I don't even attempt to meet code. I have a cousin electrician that helps when its time to finalize things.

    Also, I've obviously reassembled the motor for this demo, I don't think anything has changed with bearing alignments or preload. There is clearance between the moving parts, they spin freely on their own.

    I don't understand, are you trying to run the motor at 50 Hz? If so it will soon be burnt out. Minimum low speed under no load should never be less than 100 Hz. Mine is set at 150.

    Preloading in these Spindles has nothing to do with matched ground Bearings, which would make no difference

    They are preloaded by Belleville Washer washers or springs and only the Spindles that have the springs can the preload be adjusted

    The fan in this case may be the Nut, so care must be taken to see if the Fan is threaded

    Your Parameters settings can't be using 50Hz anywhere they have to be set at 400Hz I surprised the spindle has not smoked with using 50Hz

    The Code is saying the Parameters are set incorrect which we know by the 50Hz

    Here are the Parameters you need set, If this has not damaged the Spindle you got lucky

    Huanyang Mactec54
    2.2Kw 220v 400Hz Air Cooled

    PD000=0 ( 1 For Parameter Lock )

    PD001=0 (1 For Remote Control)

    PD002=0 ( 1 For 0-10v Terminal Control or Remote Trim Pot Control )
    ( J1 Also Needs to be set for Remote Terminal Control 1-2 jumper connection )

    PD003=400

    PD004=400

    PD005=400

    PD006=5

    PD007=20

    PD008=220 (Motor Rated Voltage )

    PD009=15

    PD010=15

    PD011=120 ( 120 Minimum Setting VFD, 150 is Safe for air cooled for startup )

    PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings

    PD014 Acceleration=8 ( Adjust to suit)

    PD015 Deceleration=8 (Adjust to suit) ( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)

    PD023=0 ( Forward Run Only )

    PD041=8 ( Carrier Frequency up to 10 Max for these Spindle motors)

    PD120=120 ( Stall Prevention )

    PD141=220 ( Motor Rated Voltage )

    PD142=8 ( Or Motor Max Amps )

    PD143=2 ( Motor Number of Poles)

    PD144=3000 (Max Motor RPM) 3,000= (24,000)

    PD70=0 ( This may need to be set to 1 if Control Voltage is 0-5v )

    PD72=400

    PD73=120 ( 120 Minimum RPM Setting 150 is Safe for air cooled spindles at startup )

    PD174=??? ( To Be Set to the VFD Drives Max Rated Output Amps )

    As you never took the Spindle completely apart you would not of changed anything with the preload or Bearings, Just make sure the front Nut is as tight as it was before around 60ft-lbs

    We don't have your Spindle spec's so i'm guessing that it is 400Hz, if your spindle is 300Hz then all the 400Hz Parameters need to be 300Hz

    I’m following the YouTube video on configuration of Huanyang VFD. He put 50hz for US. I have only changed from 400 to 50 for this video. It did not affect the speed for some reason. I am away but believe all other settings match your description. Will confirm.

    It would depend where the what Parameter was set to 50Hz as to how it would affect the speed

    Never go off what the Videos on YouTube use for settings, they are just trying to get going with no idea of what they are doing

    Ok I have changed all those settings over to what you said and with the same result.

    The reason we let you recheck is that if you do not set it at 400, then when you run the spindle motor, the spindle motor will be over-current, then the spindle will very hot and then within 5 minutes, it will broken.
    Ok lesson learned, must have been 50 hz at some point. This really sucks out $300 bucks now

    Is there any upside to my situation??

    Try

    PD006=2.5

    I think the wiring was the cause of the whole problem, and may still be, if your cousin is not an industrial electrician he may also not of had any experience on how to wire a VFD to Spindle like this using the correct cable you need to use

    IGUS is one of the best for the cable you need it is CF6-15-04 This is a 4 wire cable with a shield, the shield has to be terminated correctly also
