Enable spd=0 I Enabled TheIcomponentofthespeedregulatorissetto0whenthe
referencevalueandtheactualvalue=0.Thedrivecontrolis
thenonlyproportional.TheIcomponentisenabledwhena
referencevalueisenteredtorestartacceleration.
 Disabled Disablethefunction.
Enable spd=0 R Onlyeffectiveif Enable spd=0 P isenabled.
 Enabled Theproportionalgain,equaltoSpd=0 Pgainatzerospeed,
isequaltoSpeed Pwhenthespeedreferencebecomeshigher
thanthevaluedenedbyRef 0 level.
 Disabled Theproportionalgain,equaltoSpd=0Pgainatzerospeed,is
equaltoSpeed Pwhenthespeedreferenceortheactualspeed
becomehigherthanthevaluedenedbyRef 0level.
Enable spd=0 P Enabled Whenbothreferencevalueandactualvalue=0,thepropor-
tionalSpd=0 Pgaincomponentisactiveafterthedelaytime
denedbySpeedzerodelay.
 Disabled Thespeedregulatoralsokeepsitsproportionalgaincomponent
whenthedriveisatastop.

TheSpeed-upfunctionisusedinordertoavoidoscillationsinpresenceofloadswithahighmomentofinertia.
Itismadeupofaderivativepartinthespeedfeedbackcircuit,whichallowstoincreasetheintegralgainofthe
speedregulator.Itisalsousefulincaseofcyclicalnonconstantloadsonthemotor(ex.cams).Thefeedback
appliedtothespeedregulatorismadeoftwocomponents:
- themotorspeed 
- theoutputsignalfromtheSpeedupfunction
ThisfunctionismutuallyexclusivetotheInertia/loss compfunction,ThisselectionmustbedoneviatheAux
spd fun sel [1016]parameter.(SPEEDREGULATmenu).Seesection6.7.1Speedregulator.
