If I set P00.01 =0 then the speed control works by the panel speed control knob. If I set P00.01 to either 1 or 2 the panel speed control knob doesn't work any more, but also the software control also does not control the speed, it runs at full speed in both cases when I activate the software spindle on.
There seems to be other settings that are not explained in the manual P70.08 - P70.15 enough for me to understand, and I think that may be the reason that the software is not controlling the speed.
I have attached the PDF manual for this VFD.
