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.

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?

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?

[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.

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

Well this is an expensive lesson to learn!

[SamHam]

Mactec54, on those other settings - should i be using any of them?

Is it running again?
The problem when attempting to repair these units is the identification of some of the devices which has either been erased or not legible making it almost next to impossible to repair, unless very lucky.

Unfortunately not. I've resigned myself to the fact that I messed up and need to replace it. Just want to be ready when that happens.
I'll probably take this one apart and see if there is anything obvious, but I am not skilled in this type of electronics.

[Al_The_Man]

At least you will have some spare parts!

[mactec54]

I can't post to your reply some problem again with me posting see if I can post to myself

Well looks like that worked I will try and add some content

As I Said before you have to be careful what you change

PD175=0 this is normally also a read only Parameter you want it at ( 0 ) for constant Torque

PD176 is normally a fixed Parameter which you can't change and is not required to be changed as this has nothing to do with NA 60Hz power supply frequency
No input power frequency 50Hz or 60Hz is used for what you are using your VFD Drive for, this Parameter is just telling you that this VFD Drive was
suitable for Europe Etc where the frequency is 50Hz

PD120=100 for you would be normal if I had what spindle you are using I may give you a different number this is for stall protection which uses your
max amps of your spindle motor 100=100%

PD010= could never be set at 120 that would be bad 12 is a possible number though

without your spindle spec's and manufacture I can't give you any other Parameters to change as

PD006=
PD009=

PD007=
PD010=

Each of these 2 PD pairs work together and must be correctly programed they work off V/Hz ratio and to give any numbers for these I would have to know all
the information on the spindle you are using

[SamHam]

According to my book:

PD175 = Inverter model
PD176 = Can be set to 0-50Hz or 1-60Hz Factory is 0
PD120 = Stall Prevention - 0-200% Factory is 0
PD010 = Min Starting Voltage Factory is 8 for 220v class

I have not changed any of these (including the 06,09,07,10

I should be safe leaving them at Factory, except for PD120. If left at 0 that would disable stall protection. So that I would change to 100.

Does that sound workable?
