My Bridgeport Interact 2 mill has two speed control elements: 1) A constant power belted vari-speed control, and 2) Variable frequency drive.
The vari-speed control can potentially be operated from EMC also, as it is based on a pneumatic motor controlled by two valves. Right now the control is not hooked to EMC in any way, and I operate the valves with a standalone switch. I would like to somehow control speed with the S parameter. My current idea is that S is strictly responsible for frequency and goes from 0 to 60. So the value of S is strictly the driving frequency and it has nothing to do with the varispeed. For now, I will continue to operate the valves by manually using the switch control handle. If I ever want to control varispeed automatically, I could do it with a M100 shell script, if I hook up the valves to the PPMC control. The reason for wanting to use the varispeed, of course, is to be able to change spindle speed and keep power, while operating a wide range of tools within one program. Does this approach of setting S from 0 to 60 (hertz) look flawed or weird to you? I do not want my mill to be weird, in the sense of an old CNC operator finding its operation counterintuitive. i ------------------------------------------------------------------------------ Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
