In UM2022, Appendix C Motor electric constant (Ke) measurement written:"Measure the peak to the frequency ratio" (by oscilloscope).Our question: what voltage to measure EXACTLY ?:Vpeak-to-peak, Vmax, Vmid, etc ??I think it's fundamental to get the ri...

Dear Peter,seems like to be: one Peter of two Peters has a habit to own the last word :)So, if documentation would have contained words "Peak amplitude" (not only term "peak voltage") I would not have asked the question.As this is not the case I hope...

Dear Peter,First of all: thanks for your kind reply.My opinion in short: may I advise: to clarify relavant part of UM2022.Something like: "Measure the zero to peak voltage (Vpeak-to-peak /2) .. or make an additional signs to picture , e.g.: m'I right...
