Yeah, I hear you. I try to acquire as many parts I can from North America for the product I build. Unfortunately, I still have to rely fairly heavily on Asian sources.

Call Yaskawa support directly. They are very helpful and will answer all of your questions. Their support is second to none.

Oh, and I am not afraid of stating who the distributor was I dealt with - CNC4PC. They provided as much support as they could, in my opinion. They even contacted the manufacturer on my behalf,...

Makes little difference to me what you think friend. A fair chunk of change and a great deal of time was spent on these units. Now they are sitting here, collecting dust. Let this be a warning to...

See my other post.

I appreciate your response friend. I have moved on and deployed the Larken drives, which exhibit no issue(s) whatsoever. But just for reference, I will respond to your questions:

As mentioned, I...

Oh boy, where to start...

Yes, I took every avenue available to me. Believe me, I was very pleasant when dealing with the distributor and much later, the manufacturer. Pleasantries eventually go...

Good warnings all around. Considering I have an electronics background, these units are in no way damaged by me. Many weeks were spent tweaking the power supply driving them, wiring and rewiring...

Well, if you want 3 more, they are yours for a good price! You have no idea how much time I spent working on these things bro. Months went by!

I finally threw them in the corner and moved to...

I'm sure this post will get deleted, but I hope I can save someone some cash by not selecting this product. Bought 3 DG4S-16035 drives for a mill with servo motors I was retro fitting. I spent many...

Nice product, great support. Thanks Larry, your drives are first rate.

Mark :)

Did you disconnect the limit switch wire to make sure it isn't a reed switch issue?

I know this is an old posting, but certainly a valid question.

I too own a 250 which I will be dropping into a retrofit. Here is Larry's response to the question:

The bottom 2 are step...

Thanks for the response. Kind of figured so.

Anyone want to buy some CamSoft software? Cheap?

Hi folks,

Hoping someone here can help. Getting no love from Camsoft - only a nice fat bill for something I have yet to use.

I have AS3000 software with a USB dongle. Install of the software...

Started having computer issues that I couldn't recover from. So I'm parting it out. No unreasonable offers refused. Collet chuck, servos and amps, 15hp spindle motor and amp, boards in computer,...

Great post. It has been quite some time since you posted, but I am very curious if you resolved your problem. I too am experiencing the same issue as you are. The scrolling words on the screen;...

I had a 1994 unit. The high/low range was adjustable with the unit off. The lever should move outward to make the change if memory serves.

Your noise(s) is probably from the motor pulley. Its...

Gee, this is almost turning into a blog...

I found the issue. As it turns out, the main power supply was shot. The supply is made up of a simple bridge rectifier, 5400uf cap and a shunt...

Well it turned out to be a bad fuse on the main line. Got that figured out. Now onto problem two:

Who here knows about signal feedback? I'm now receiving an error when trying to move any of the...

So, I fired up my newly acquired Clausing/Kondia mill for the first time today and five minutes into testing things, I hit the Emergency Stop button to make sure that functioned. Well, it worked -...

I have a simple project for someone in Winnipeg who feels like doing it. Single wood piece ~17" round cut at an angle I cannot do. Will pay dearly.

PM me please.
Thanks,

Shoot me a PM if you are capable of cutting some 3/4" MDF "risers" - ~9.5" OD, 8.75" ID. I need 50 pieces done.

I can provide more details.

Thanks,
Mark

Moved this post to a different section.

From what I can tell, yes. The motors are DC servo and I can't see the company investing on 220v power supplies when they don't have to.

Anyway, here's a few pics. Shot of the old ISA controller...

I took my camera to the shop to take some pics of the process but the batteries were dead. I went ahead with the hardware transfer. I will post a few after shots of the setup however to give you an...

I'm not sure how much interest this will be to folks, but I thought I'd share anyway.

I fired up my YCM-40 (1993 model) for the first time today only to witness the computer die after the second...
