Should it be possible to measure the 0-10v signal?
I thought so, but I tried measuring the input to the VFD from the BOB and as soon i touched the VI & ACOM pins in the VFD the motor stopped as if the input was being shorted out?
This was with an expensive Fluke DMM on DC volts, i was expecting to see something 0 and 10v here??
Odd?
