Thespeedreferencevaluespeciestherequiredspeedofthedrive.Thedriverespondstothereferencevalue
progressiondirectly,exceptincaseswherethetorqueavailableisinsufcientforthispurpose.Inthiscase,the
driveoperatesatcurrentlimituntiltheselectedspeedhasbeenreached.Thespeedreferencevaluedetermines
thespeedofthemotor,whilethepolaritydeterminesthedirectíonofrotation.
