Caution
WhensettingPr0.08,andencoderresolutionisautomaticallysetupasnumerators.For
fullclosedcontrolling,settingofPr0.08isignoredandsettingsofPr0.09andPr0.10are
alwaysapplied.
•Max.inputpulsefrequencyvariesdependingoninputterminals.
•Thedesiredsettingcanbedeterminedbyselectingvalueofnumeratoranddenomina-
torofelectronicgear.However,anexcessivelyhighdivisionormultiplicationratiocan-
notguaranteetheoperation.Theratioshouldbeinarangebetween1/1000and8000.
 Excessivelyhigh multiplicationratio will cause Err27.2 (commandpulse multiplication
errorprotection)duetovaryingcommandpulseinputornoises,eveniftheotherset-
