After years (about 7) using a router and SuperPID, I have just completed an upgrade (rebuild) of my CNC and decided it is time to switch to a spindle.
After reading a lot of posts and taking Mactek54's advice I ordered one with Pin4 grounded and ceramic bearings. This one in fact. https://www.aliexpress.com/item/3280...72fa522dJJL7jJ

Now I'm trying to get ready to install it so am looking for guidance on a couple of things.

1. According to the chart at the bottom of this post, it looks like a 20 breaker would be enough. Is that correct or should I go with a 30 amp?

2. Is 18/4 shielded wire ok for connection from VFD to spindle. It would be about 25 feet in total.

3. I copied these settings from another post a while back - I think from a post by Mactec54 but not sure. Are these settings still good?

D000=0 for Parameter unlock ( 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 Terminal Control )

PD003=400

PD004=400

PD005=400

PD007=20

PD008=220 (Motor Rated Voltage, If you have 120v spindle then set to 120v )

PD009=15

PD010=8

PD011=120 ( 100 Minimum Setting with Quality VFD, 120 is Safe)

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

PD014 Acceleration=12 ( Adjust to suit)

PD015 Deceleration=12 (Adjust to suit)

( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)

PD141=220 ( Motor Rated Voltage ) (120 for VFD Rated for 120v )

PD142= ( Motor Max Amps)

PD142=( 220vSet for your motor Amp Rating 2.2Kw Spindle 9 amp )

PD142=( 220VSet for your motor Amp Rating 1.5Kw Spindle 7 amp )

PD142=( 220v Set for your motor Amps Rating 800w Spindle 4 amps )

PD142=( 120v Set for your motor Amp Rating 800w Spindle 7 amp )

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 ( 100 Minimum Setting )

Anything I am missing?
Thanks for any input.

Thanks for any input.

Input power wiring to the VFD Drive should be connected to R and T plus Ground, an EMI Power Filter should be mounted close to the the VFD Drive input Power connection TDK Lambada RSEN-2030L

30A supply is the norm for a machine that is using a 2.2Kw with 240v supply you want this supply to be a 4 wire so you can use 120v /240v if your machine has and 120v circuits

VFD to Spindle cable should be CF6-15-04 from IGUS this is around 16 gauge this is the best cable to get there are other similar manufactured cables no all are created equal

[SamHam]

Thank you. Just ordered that cable.

What about the settings?

[mactec54]

Thank you. Just ordered that cable.

Shield Grounding is very important so you need a metal plate Aluminum that you mount everything on the cable Shield at the VFD end is clamped to this mounting plate which is the Ground Plain at the spindle end all you can do if you use the plug that it comes with, you roll the shield back and clamp it under the cable restraint I will post some snips if you have not already seen them on shield Grounding

PD011 can be as low as 50 for your spindle
PD073 can be as low as 50 for your spindle I would start these at 80 and go down in 10s just see how the spindle reacts

There can be some other changes but post how it runs at the lower speeds if it looks like it would stall at the lower speeds then put them up to the 100 for safety

[SamHam]

Thanks,
I think I am clear on the shield grounding, but would like to see you diagrams just to make sure.

If you are using the RS+ & RS- terminals, these are the serial RS485 for Modbus protocol communication.

Finally found time yesterday to get it running. Seems to run fine. In going through some other posts I find one that you also recommended a few more settings than the ones I had originally. Are these still valid inputs?

006 - 5
007 - 20
009 - 15
010 - 120
120 - 120
175 - 1

Also, here is the US, should I change 176 to 2 for 60Hz

Thanks again for all your advise.

[SamHam]

Well Disaster has struck!

I was about 75% through a job of milling some aluminum plates when I hear a pop from the spindle and a wisp of smoke. The VFD was also dead - as in no lights at all.
There was no warning, just happened.

The spindle was not even warm. I had run it a good 15 minutes before I ever started. It was running at 14000 rpm and at 26 in/min. The doc was .o4, so not really taxing.

I verified there is 240 volts to the VFD still.

What to do now?

[Al_The_Man]

Sounds like a fault in the spindle, you would need to do a Megger test of the windings and to Earth.
Was the spindle body grounded?

I'm not sure what a Megger test is.

I did a continuity test on the spindle.
I have continuity between ground pin and case (i double checked that the ground pin was connected to the case before i did anything else).
I have continuity between any two of the power connectors.
There is NO continuity between the ground and any of the power connectors.

What is concerning is that the VFD will not power up.

Check the inside of the spindle plug the Plug on the VFD to spindle cable plug, it sounds like you have had a dead short between the pins

I have not been able to post something with the Zone server

So in your other post you asked about different Parameters so I hope you did not change them as there was one you posted that is not correct

A Continuity test is all that is needed to check these spindles

Pin 1-2=
Pin 2-3=
Pin 3-1=

These should give you a number and they will or should be close to the same

This is at the spindle to do this check

[SamHam]

Glad to see you back Mactec54

1-2 001
2-3 001
3-1 001
Ground to case 000

I did not change any of those settings since you told me to wait on them.

The Zone is still not working right for me

001 does not sound like a good number, Set your meter to Ohms and then do the test

[SamHam]

Sorry, had it on the wrong settings

1-2 2.2
2-3 2.2
3-1 2.2

So the spindle seems to be fine what about the Plug on the end of the cable going to the spindle I suspect that there was a problem in the wiring of the plug post some photos of it if you can

[SamHam]

You are right. One of the solders must have come loose. The plug is fried.

If the VFD does not power up does it mean it is also dead? Is there any kind of reset on them?

No a dead shot like this normally takes out the VFD Drive, these connections have to be perfect and insulated with silicon so this can not happen, the best way is to do away with the plug and use crimp fittings and a Gland suitable for use with a shielded cable

[Al_The_Man]

Most likely took one (or more) of the IGBT's out, a short of this nature can also take out the main supply to the LV transformer which of course makes the display dead also.
