Hi guys, I hope you're all doing well Quick question to define a little issue I have. I purchased a VFD that I wrongly thought had a pulse train input for speed reference. Turns out that feature it's optional so I need an additional card to have it. By the way this Simphoenix E280/E580 VFD can reach more than 800 hz so it's a good candidate for high speed spindles (which is the main reason why I purchased it).
So my question is: Is it that difficult to modify the firmware on the 7i95 to add at least 1 PWM generator so I can easily convert that to analog voltage? Because if not, I need to make a frequency to voltage converter which is a little trickier. I prefer the PWM option of course. Thanks as always for your help and knowledge :) _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
