I looked at the machine today and pulled the y-axis servo. Apparently NASA's definition of machine working when taken out of service doesn't consider the fact parts were removed. The y-axis encoder is MIA. I did speak with Glentek today, they let me know the "special" designation was that they didn't include encoders in the servos. I'm going to check the other axis servo tomorrow. I'm uncertain if I have the power supply for the drives or not. I'm leaning towards they were part of the drives that were removed. There is a large capacitor that is labeled Glentek and all 3 drives were wired into it. I have 4 wires on top where the drives were. 1 white, 1 black, 1 red and another black. The white and black go to the servos. The wiring is done incredibly if only i had the road map aka wiring diagrams.
Oh I don't see any glass scales and there are wires in the servo where the encoder was likely connected. I will continue pecking away at it trying to figure out what i need to bring it back to life. ________________________________ From: andy pugh <bodge...@gmail.com> Sent: Monday, July 20, 2020 2:49 AM To: Enhanced Machine Controller (EMC) <emc-users@lists.sourceforge.net> Subject: Re: [Emc-users] Need help with Bostomatic BD18-2 to linuxcnc On Mon, 20 Jul 2020 at 02:44, Tom Smart <smart_tow...@hotmail.com> wrote: > The motor is this glentek GM4040-41 180vdc, 9.1A.

Everything else sounds like a simple retrofit, DC servos are relatively easy. Do you have the power supply? If so, what is the actual output voltage? The Pico servo amps are close: http://www.pico-systems.com/pwmservo.html but may come up a little short if the actual power supply voltage is 180V. The 7i29 from Mesa http://store.mesanet.com/index.php?route=product/product&path=83_90&product_id=141 also comes in a little low on voltage. (Note that you can run two motors from each 7i29) If you don't have the DC power supply then perhaps you could look at AC input drives, https://www.a-m-c.com/product/ab30a200ac/ might be an option. But AMC make so many drives it's probably best to actually talk to them. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
