The second MM was easy, but the building's electrics were noisy #28 - Orlando, FL

Hello all.
Well, a good friend up the road (TIM) has a construction company and has found themselves in the need for a CNC machine for various uses. Being fairly experienced in building the MM, I was able to convince them this was the machine for them.

I have agreed to "mentor" them in their build process and will be tending to the forum duties for Tim along with fairly frequent shop visit's to check on build/fabrication process.

This being my 3rd build to date - I hope to have some fun! Plus with Nils and my existing table as reference it should go a little easier and quicker this time.

The specific's based on their needs:
5' x 10' table
3 axis
2.2 kw spindle
pmdx 122
56V transformer with 12 & 5 volt taps
gecko 203v drives
7,2 Geared OM motors
(the same powertrain and control box as my #5 and Nils Machine)


The component ordering started yesterday along with cutting steel. This should be a quick build as long as all the parts get here in quick fashion.

Sean #5

Sleep? With my 1 and 3 year old's running around the house I am awake anyway. So why not make use of that awake time!

Sean,
Saw your post about your new spindle being ordered. Let us know what model you got and pros and cons versus the porter cable router you are using now. Is that for this new table or your older one?

Brian,
Actually, Blurry Customs (you can find them in the Market place section of this forum) is running a package special.
For about 2300$, You get a complete 3HP spindle, drive, collet, wrench and Cable package. Best price I have found to date. Plus, very timely customer service and phone help thus far.

Looks great, enjoy. We are looking forward to seeing it on the machine.

BTW, I thought we had mentioned the upgrade to the Delta. If it's an issue, please let us know, and we'll make it right. Otherwise, enjoy that sensorless vector control on the Delta.

Alex,
We talked about it and I forgot I said yes! It's perfectly fine...I prefer the Delta. The difference in cost was minimal for a drive I prefer.

Regards,
Sean

How is the thermistor handled with the Delta drive?

Well, now you have me making some phone calls. I know how it was handled on the Hitachi. I will have to look into it. As you are well aware, the delta VFD-b series in the 2007 < vintage drives handled it fairly oddly. The addition of a series relay may be in order if the RV series Colombo spindle has an accommodation for it. I'll get back to you after some homework.

Okay, some answers after talking with the spindle engineer at PDS.
The Internal Thermistor coupler on the Columbo Spindle (yep, has one) is connected to the Delta VFD via terminals DCM and M14. This is designed to fault the drive and initiate a shutdown at 110C. (or roughly 45 degrees F above ambient) Anyone of the Aux contacts can be used an output to trigger another stop. An extra relay and wire it in series with the e-stop circuit to the pmdx or interupt is the ticket. {good thing I have plenty of extra little PCB relays I am using for the proximity circuit for the additional dry contact}

The current Delta VFD has some significant upgrades and changes since the 2008 model year.

I think this answers your question Gerald.

Sean, it is this discussion that got me kicked out of the ShopBot community:

http://www.talkshopbot.com/forum/mes...html#POST41164

followed by:

http://www.talkshopbot.com/forum/mes...tml?1160501868

and shortly after that they went to Yaskawa drives.

I am still not convinced that the Delta VFD is designed for taking a thermistor over DCM and MI4.

I recall that conversation between you and Eric back in 2007.
I will look further into this - I haven't done anything except open the shipping box.

I use Delta series drives frequently in my line of work for standard machine automation and control, but never for the spindle.

....more to follow.

Interesting.
I uploaded pictures during lunch today and now I can't find any portion of the thread. Well, Anyway. I am almost done with Machine #2. Just wiring the last bits up. Hopefully, I will be cutting before the weekend is over.

I am nervous of those tightly bundled parallel wires, unless they are screened. Is your first control box also like that?

Gerald,
Of course you noticed that! I caught that after I took the picture home last week!

I already gave the shop the note to fix the routing of wires in the panel.

I think it's already been fixed. I haven't looked in the cabinet since last week.

OOps,
Yup Gerald is right, very neat but not shielded. That will teach me to comment after midnight.
