I forgot to ask how would I calculate the loss of abilities of the mill if i don't drive the servos with their maximum rated power and amps? If I were to get drives that weren't rated to 180vdc what losses will i have and how do i calculate the loss?
Thanks for the assistance, Thomas ________________________________ 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
