Speed ref 1 1streferencevalueforthespeed.Thevaluetobeentereddependsonthefactorfunction.
Speed ref 1 (%) 1stspeedreferencevalueasapercentageoftheSpeed base value
Speed ref 2 2ndreferencevalueforthespeed.Thevaluetobeentereddependsonthefactorfunction.
Speed ref 2 (%) 2ndspeedreferencevalueasapercentageoftheSpeed base value
Speed ref (rpm) Totalspeedreferencevalueinrpm.
Speed ref (d) Totalspeedreferencevalueinthedimensionspeciedbythefactorfunction.
Speed ref (%) TotalspeedreferencevalueasapercentageoftheSpeed base value.
ThetotalspeedreferencevalueconsistsofthesignedadditionofSpeed ref 1andSpeed ref 2.
note: Speedbasevaluecannotexceed8192rpm.
Example1: Speed ref 1=+50% Speed ref 2=+30%
Speed ref=50%+30%=80%
Example2: Speed ref 1=+40% Speed ref 2=-60%
Speed ref =40%-60%=-20%
0...10V,0...20mAand4...20mAsignalscanbeusedwhensettingthereferencevalueviaterminals.The
speedreferencevaluehasanupperandalowerlimit.
Iftherampisselected,(Enable rampparameter=Enabled),thereferencevalueinputSpeed ref 1isautomati-
callylinkedwiththerampoutput.

[40] Tcurrentref2[%]
Thecurrentreferencevalueisproportionaltothearmaturecurrentofthemotoranddeterminesthetorque,the
polaritydeterminesthetorquedirection.FormostapplicationsT current Ref comesfromthespeedregulator
output. T current ref 2 canalsobeusedasacorrectionvalue.
