Prop lter Timeconstantofthelterbelongingtothecircuitofthespeedfeedback.Filteringof
thehighfrequencycomponentsofspeedfeedbacksignalisusefulincaseofelastic
couplingbetweenmotorandload(jointorbelts).
ThespeedregulatormustbeenabledwiththeEnable spd reg parameterinorderforittobeused.
ThereferencevalueforthespeedregulatorconsistsofthesignedadditionofSpeed ref 1andSpeed ref 2.
Thespeedfeedbackissuppliedbyanencoderoratachometerthataremountedtothemotorshaft.Thehigher
theresolutionoftheencoder,thebetterthecontrolaccuracyoftheregulator.
Theregulatorparameterscanbesetseparately.
