I'll be using 3 phase. I here if I was using single phase I'd want to upsize the VFD.

Just like you said I just purchased a CIMR-VU2A0040FAA 10 HP Yaskawa drive new in box for $500 shipped.
...

Also based on the motor nameplate that I would need a 20 hp rated drive? looks like it might draw as much as 53 amps and a 20 hp drive is only rated up to 56 amps i'm guessing a 15 hp drive might not...

Thanks Mac.

The turrents I've seen using the acorn are setup as an axis. I could probably do it by replacing the existing motor with a servo. Not sure I want to as long term I think I'll move to...

Thanks for the feedback Jim,

In your case I could see the reason to want a feedback loop from motor to drive where you are looking to have positional c axis capabilities.

Mine will be a simple...

Good Evening All,

I've been sitting on two mori seiki slant bed machines for a couple years both with varying control issues. Basically resigned myself to parting off the controls and doing a...

Does anyone have any results or further inputs on this issue?

I have two lathes with LX1 controls on them. They are both throwing a Error 400 Seq2 Alarm. (Sub text says Spindle Alarm).

I'm...

How about this one.

Or a Hitachi WJ200?

Evening All,

Starting a new thread. Got my new to me Fadal VMC15 up and running and I appear to have a fried servo drive. Keypad on Drive just Flashes along with the FWD and REV keys. Spoke with a...

So I decided that troubleshooting with my changes thrown in the mix was probably causing issues that weren't accounted for so I bit the bullet and wired up the phase converter this weekend. I didn't...

Did you ever figure this out?

I tried bypassing the transformer altogether and have similar faults. I'm considering just sticking with the three phase transformer. I'm not sure if the machine...

Apparently I don't know how to use a multi-meter. power supply fan is dead but power supply appears to be working. (I was checking voltage from ground to the terminals. Voltages looked good when I...

I removed the Jumper and that didn't change anything on the VFD. I also switched power from L3 to L2 on the VFD and that also didn't seem to do anything, but there may be other issues at hand.

I...

Hmm, I'll try without the jumper and see what happens. Hope I didn't screw it up by jumpering.

Checked the power supply. Its toast. At least its not running. Not showing voltage going in or out....

I'd agree with that. I spoke with my maintenance supervisor at work and he considered a few extra volts to be nill. His response was that the power companies won't guarantee anything better than...

So according to this link

https://www.fadalcnc.com/media/pdf/Properly_Tapping_Fadal_Tranformers.pdf

They appear to want you to stay under 240V. So I've got an idea. Again might be dumb, but I...

Just to clarify. You have a 3 phase transformer and just completely bypassed it? Thats my plan. Some people buy the T813/T814 Single phase transformer, but what I am getting at is I don't think I...

So i'm sure this sounds kinda dumb at first, but lets start with what the machine requirements are. 240V at 60Hz. That is the whole point of the transformer right. To take the variable power that you...

Do you have any specific manufacturers?

For same money, at DMM, you get new and a warranty. That right of way should tell you something.

Usually when I can buy something off the shelf for the...

Thanks again for all the replies. I go back and forth. I would really like to be able to learn how to work with servos and drives. Plug and play sure is nice and tempting, but you'll end up trouble...

Thanks again Mac,

Is the Apex 6151 drive step/dir controlled? I read the manual that I was able to find and I wasn't able to tell. Also the parker motor doesn't have much literature that I could...

Just spent some time looking around ebay. Boy are there a ton of options on there. In particular alot of stuff coming from South Korea. Still not cheap stuff though. Not sure if they are willing to...

Good Afternoon Mactec,

First just wanted to say thanks for your previous help on my bridgeport boss mill micro-v belt conversion. Its finished and working well. I like it a lot.

Back to the...

Good Morning all,
Am considering trying to build a CNC table to attach to my lathe. Something I can pull off rather easily. Current plan would be to go with something like an Accuslide/Omniturn...

Good Afternoon Folks,

Just wanted to ask a question about pendants. Been looking at the different pendants from Vista CNC and wondered if there was any consensus as to which version was better or...

When you talk about a D6 Driver I imagine you are referring to the SS2000D6 Slo Syn drives I see on ebay? Thanks for your input I really appreciate it. I've heard such good things about gecko all...

So you would recommend a new driver and power supply even with the old steppers and this would also give the ability to upgrade the steppers as needed in the future? Do you have some particular...

Machine is currently set to 60 IPM Rapids. Fine for my uses. I just figure with the age and unkown amount of abuse on these steppers I ought to be ready to replace them. Given the drives I already...

Good afternoon all,

Been awhile since I have had time to play with any CNC related items, but its always been at the back of my mind. Finally moved into our first house and it has just enough room...

Good Morning all,

I picked up a used Interact Series I off of ebay a couple months ago, I think it is a boss 5. I haven't had a chance to do much with it, but I am just starting to get to it.
...

I've been thinking about this quite a bit since you mentioned it and I think I might try to build one. Seems like a great way to keep a good bridgeport both manual and cnc when you need it. Am going...
