1. In a word, Yes, I think. The SEM's were the brand of motors used on MANY different variation of the DX system. These motors ran on mills (2, 2.5 & 3D), lathes (Expath 1 and 2), and grinders (Ezsurf) and some VMC's (3D and 4D). They were sized in accordance with the power requirments of the particular machine.
2. The ones I'm familiar with were all interfaced thru an ISA slot in a PC via the BMDC card. This controller card had a 12bit D-A chip on it that generated the +/-10vdc analog drive signal that went to Motion Science, Siemens and other servo drive cards. |
