Theselectionofthereferencevaluesiscarriedoutviathekeypadortheserialinterface.
Thereferencevaluesaresignedsothattheycanbedenedforaparticularrotationdirectionofthedrive.Asfor
theTPD32-EV...2B...thereferencemusthaveapositivepolarity.
WhentheMultispeedfunctionisenabled,Multi speed 0isdenedbytheadditionofthereferencevalues
