Hi All, My VFD has an analog output which can be programmed to indicate either output frequency, current, or power etc.
I'd like to read this into EMC so I can monitor and plot the spindle load while the machine is running. I have a M5i20 card which doesn't have analog inputs, so I'm wondering if any of you know a nice simple way of converting the 0-10 V into either PWM or a pulse-train (FM) or something else that can be read by one IO pin (read say every 0.1 ms) on the m5i20 ? I know a small 8-pin PIC could do this easily but if there are ICs that do this out there I'd like to avoid the programming...
