i have a vfd drive that accepts 0-10v analog voltage for speed control
i am having a dac connected to pic micro it outputs 0-3.3v analog signal using op amp i am converting to 10v signal
my doubt is can i add a series 1k resistor between the op amp output and vfd input will there be any issue. how much current that the vfd analog input consume? i am adding the 1k resistor for safety if any short in the analog the op amp will not blow.
