Thiscongurationallowstheuseoftheencoderinputs,asaspeedreference.Comparedtoananaloginput,these
inputshavehigherresolutionandhighernoiseimmunity.
Usingforthispurpousetheencoderinput(XE1orXE2connector),itisnecessarytodenethedestination,
selectingproperlythetypeofspeedreferenceonwhichithastointeract(Ramp ref 1,Speed ref 1,etc.)
Whentheencoderinputisusedasaspeedreferencesource,usingthesameencoderinputasspeedfeedback
isdisallowed.Itisimpossibletocongurethesamespeedreferencetotheencoderinputandananaloginput.
Thefunction“Tachfollower”canbeusedinaccordancewiththetabebelow:
