Provisions
Inordertomakethecommissioningprocedureeasieranduniform,thesystemcontainsaclausereferringtothe
speedandtorquedirectionstoberespected:
Asageneralrulethewinderspeedandthetorquedirectionareconsideredpositivewithaupperwindingside.
Allthepossiblesystemcongurationsstatedintheexamplesbelowrefertothisclause.
note! Thepolarityofthelinespeedreferenceisnotimportant,becausethesystemstatestheoutput
referencepolarityonlyaccordingtotheparametersWind/unwind andWinder side.
