vfd

I figured this would be as good a place as any to ask this so here it goes. I got a few circuit board drill/spindles from an old friend who used to work in that industry. They are brushless, about 2” diameter about 8” L, with a collet type nose that im guessing a max cap of 1/4”. They have a 3...

CHNC II, If you have ever swapped a generic VFD on one of these lathes that use a General numeric AC spindle motor I would appreciate knowing specifically if you had any problems with motor compatibility. The nameplate shows 200V and I plan on running it on 230v. I can get one of those motors...

Newer member here, but just wanted to share my experiences with my first large late- a 1979 LeBlond Regal Servo Shift 15"x54". Information on these machines online has been a little bit scarce and troubleshooting has been frustrating, especially because most issues with these lates are...

Howdy! I'm having a weird issue with a VFD setup, and I can't figure it out for the life of me. I've tried searching the forums, the goog, and basically any forum that I think could have info but either I'm not searching the right terms or this issue is kinda unusual or both. I'm very new to...

After too much research and studying the probably overbuilt electrical box for my Index 645 mill is installed and functioning. The heart of the electrical system is an Automation Direct GS21-21P0 which is a .75 Kw 240V single phase to 240V 3 phase VFD. Automation Direct recommended not...

I'm considering getting a "cheap-azz" VFD, and I've narrowed down my search to 2 manufacturers, I've skimmed over manuals to get an idea of the feature sets, and to get a sense of their quality. Of course, there's only so much you can learn of infer from a manual, but I find that manuals give a...

I am building software for a demo brewery and need to get my hands on a very cost effective 1ph VFD (it wont be hooked up to a motor as its a demo only) that has proper Modbus documentation. My production brewery uses Delta VFD's exclusively and they work great and as stated here the...

Ever since I got the oil leaks fixed on my Colchester Chipmaster/Harrison 10AA and have started using it, I have daydreamed about how nice it would be to have the OEM FWD/REV/Stop buttons work as inputs to the VFD. For the last few years up through when it finally got fixed early this year, it...

**Edit - Ok, I found a quick start manual for the V1000 - starting there. Looks like I need to verify the VFD is for Single or Three phase first. I'll do that and post back later today. So it looks like the lathe came wired for 3 phase, I'll be using Single Phase 220. The second line on the...

I am in the process of shopping for a lathe and mill. I am seriously considering getting a 3 phase motor and using a VFD to convert single-phase power for both. I am also very interested in building an electronic lead screw for the lathe. I am wondering if there is an issue wiring the ELS to...

Hello All, Can't remember the last time I posted but this is my go-to forum for help of all kinds! I really appreciate all of you! I am just completing my first VFD install on my old Jet 16 milling machine. Probably cost more than the mill, oh well. Anyway I would never have got through it...

I just finished running a 220v sub-panel over to where my mill is located and was looking for advice on wiring. When I purchased my Super 55 Wells Index the guy I got it from also provided an idle motor, magnetic contactor, general contactor, start capacitor, switch and timer. However, I am...

This thread is about my PM-1640TL also known as TL-1640 which I received in August, 2021. I had placed the order at PrecisionMatthews.com only weeks earlier. It was ordered with DRO and the taper unit installed. I was posting to the thread "PM-1660TL" which was started by @erikmannie in June...

Well, I'm restricted in my movements thanks to Covid19 as the entire country here is under a state of emergency. All retail stores are closed only supermarkets and pharmacies are open for business and hardware stores restricted to a couple days per week and restricted hours as well. There's...

Hello I purchased a Boley F1 lathe from Europe and would like info on how to convert from 220v to 110v and incorporating a foot pedal. I live in the USA and have heard that the easiest route I can take is to use a VFD to control the speed and output 220v on my 110v apartment connection. If I...

I have two machine restorations going on that I'm unsure what route to take so I guess I'm trying to lean on the community for input, but unfortunately I think the questions have a little bit of the chicken and the egg quandary inherently built in, but what route should one take when breathing...

I am into vintage machinery, but want to convert several of my machines so that I can use a vfd to control speed and torque. I have been very fortunate in finding unusually great deals on both inverter duty and vector duty motors. For example, today an ebay seller accepted my $40 offer (with...

What motor frame # does the PM1127 with AC motor use? This should be on the motor tag. Also wondering what brand and model VFD they come with. The earlier versions used a DC motor..would be curious what they used as well, but mostly interested in what the current AC models are...

I see a lot of questions about VFD's and some statements of personal expectations of them. I want to put this out there to set reasonable expectations for VFD's. What not to expect and frankly their shortcomings. Hope you find it informational. VFD's are actually a new spin on an old...

Hello! The Acer Dynamic is my first lathe and I just purchased it about a week ago. I'm attempting to get my shop updated with a new 40 amp circuit, 220v, single phase, outlet to the lathe (This is what I have available currently). I have the power wiring, and conduit almost done. I've ordered...
