Themaximumvaluefortheregulatorparametersisdenedbythebasevalues.Thesettingspossibledependon
thesizeofthedevice.
Theusercanoptimizethefunctionoftheregulatorbychangingthepercentagevalues(valuesmarkedwith*).
Theresultinggainsfortheregulatorarecalculatedasfollows:

=12·70%/100%=8.4
Thebasevalues...basearealsothebasisforsettingtheadaptivespeedregulator.
Whentheadaptivespeedregulatorisenabled(Enable spd adap=Enabled),theSpeed PandSpeed Iparameters
havenoeffect.Theystillretaintheirvalueandareeffectiveagainwhenthespeedregulatoradaptionisdisabled.
TheSpeed P in useandSpeed I in use parametersindicatethecurrentgainsforthespeedregulator.Thisalso
applieswhenthespeedregulatoradaptionisactive.
