tp://www.freemodbus.org/index.php?idx=32 A clever way to mount the board inside or on the VFD, as if it belonged there, would be nice, but I think the best I'll be able to do is have a separate box, which could bring the cost up. -- Kirk Wallace http://www.wallacecompany.com/machi

Re: [Emc-users] Why APT

him to join the mailing list :), but I see he has been called to a more pressing venue, darn. I was wondering if someone might be continuing his work. Looks like: http://en.wikipedia.org/wiki/SofTech,_Inc. http://www.softech.com/about-us I wonder if MIT is still working on APT. -- Kirk Wallac

[Emc-users] VFD's Without Modbus?

I'm just wondering, how many out there have VFD's without Modbus or other communication and might want it on their existing drives? -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html Calif

Re: [Emc-users] IRAMS Plan

rmistor is tied to Vss so it may need to be isolated. Itrip is on the other side of the sense resistor, so it needs to be considered too. This issue might not be easy. Maybe I can process these signals on the AVR and isolate the communications between the AVR and the PC. -- Kirk Wallace http://w

Re: [Emc-users] IRAMS Plan

t the IRAMS module in today, it's cute, I'm having a hard time believing I can run a 1/2 to 1 HP motor with it. After poking around Digikey some more, I noticed there is a 4 HP module available, I want it. -- Kirk Wallac
