I took another look at the Y axis motor on my Acra, it's a MT30M4-59. (The 9 was hard to see.) I searched eBay and found this http://www.ebay.com/itm/161076323614 with about 40 minutes to go. Snagged it for $199.99, free shipping.
All the label data matches the motor on the mill http://www.sem.co.uk/fileadmin/data/file/MT_Technical_Data_Manual.pdf Now I need three servo amps suitable for those motors and a Baldor FMD0000B-00. What I have are two Fenner SD 5-12 boards, which right now I can't find any exactly the same. There were some on eBay but not now. I'd like to get newer ones without the fiddly trimpots to adjust everything - unless I can dig up an exact match at a price suitable to its age as an electronic item instead of as if it were an antique piece of pottery. ($1,000 for *any* piece of 1980's electronics is flat out insane.) I'll also need whatever control hardware is required to communicate between the servo amplifiers and a PC's parallel port. Since I'll be staying with the brushed DC motors I should be able to use the big power supply that's in the box, which should save some $$$. And for now it looks like I'll just be using the existing glass scales for position controls. It worked 20~25 years ago with these motors, it will work now. Now I'm off to hunt up a wiring diagram for the Anilam Crusader M system with spindle control... ------------------------------------------------------------------------------ Get your SQL database under version control now!
