General Mach Discussion / Re: Software for Allen Bradley Ultra3000 Servo Drive

Thanks Craig

I can't buy it directly from the web site and I'm not sure that there is a local agent I can but it off.

I believe that there was a free software called DSAPro that will do the same job and I'd be surprised if there isn't someone on the forum that is still using it using that would be able to help me out?

General Mach Discussion / Software for Allen Bradley Ultra3000 Servo Drive

« on: August 06, 2022, 01:59:00 AM »

I have a AB servo motor that uses an Ultra3000 Servo Drive. I need the software to set this VSD up. I bought the motor and drive second hand and is now quite old. As a result I am having trouble finding the software for the drive. The AB software is called UltraWare and I believe that DSAPro will also work with it. Could someone please either tell me where it can be downloaded or PM with more information

Thanks

Thanks for all your help Craig

I have purchased the following Allen Bradley motor and drive on eBay;

AC SERVO MOTOR MPL-A320P-SJ22AA, 1.3kW, 5000RPM, and matched servo drive; Ultra 3000 2098-DSD-020. Am looking forward to getting my machine set up and running. The motor fits really nicely into my machine, its a very compact motor!

Hi Craig

Hi Craig

I get what you are saying. I see that there are plenty of motors and drives for sale on eBay for reasonable prices. This definitely looks like a good option. Am I selling myself short @ 730W, should I look at the 1.3kW? How is it that you can run your A330P which is rated at 12A continuous from a 10A outlet? Are you running all the axis drives and other electrics for the machine off the same supply?

Thanks

Keith

Thanks Craig, the size in not a problem, I could go up to 110 square. The power of 700W and current at 5A is good as I need to run the complete machine off 230V 10A wall outlet. What you are suggesting looks good. The uncertainty is if the AC can deliver enough torque. I am not sure what it will delivery through the rev range. I have had a look for the performance curves and not been able to find them. The M4-2950 B DC option specification is continuous torque of 2Nm and peak of 14.9Nm. The DC option would definitely cost more, I am trying to get the best performance for around 5A current draw

Yes you have the correct drawing of the DC motor that I am looking at. Thanks for the eBay links for the AC Allen Bradley, that's really awesome information and looks like a really good alternative. I am very impressed with the compact size of the motor. The question that I have is how this compares for torque against the DC motor. Time for some research on the net...

Yes it is always nice to have the good gear, its hard to beat quality tools. When I buy tools I like to buy quality as I know I will have use out of if for a long time. Great that you have made parts to improve your machine. It always feel good when a project works out well.
I am lucky that I work in a toolroom and have access to use the machine tools. This is coming in handy to make bits for my project.

Thanks for the reply Craig, that's all really good sound advice. I was guessing that a new AC motor with a new VFD would be a more expensive option and like you say research is the sound way to find out. Interesting that it may now give DC a run for its money. I have another reason to go to DC and that is I am remaking the spindle to go from R8 taper to BT30 taper. This will also enable me to add a support bearing on the tail of the spindle. The original spindle only has a pair of angular contact bearings at the nose end of the spindle. This is an improvement that the manufactured also made to the more recent models. With this modification there is now limited space for the spindle motor and the form factor of the DC motor is a perfect fit for the machine. So I am committed to using a DC motor. I tried to embed an image of my machine in my first post but it did not work for me. I see that there are very few images in the forum threads which is a shame as a picture is worth a least a thousand ...

Thanks
