l Pleasecheckiftheaxisisblocked.
l Trytoreduceaccelerationordeceleration.
l Ifreferencespeedishigherthanthemotor
ratedspeed,pleasecheckfieldweakening
settings.Infield-weakeningrange,the
availabletorquepercurrentisreduced.
Thespeedcontrolmightrun
away,mostlikelyduetoa
wrongencoderoffset.
l Pleasecheckthattheencoderoffsetisset
properly.
l Ifautocommutationisused,re-viewtheauto

possibleconditions.
l Iftorquemodeisused,reducetorque,ensure
externalspeedlimitation,orincreasespeed
controlgainforstrongerlimitation.
ThisispossiblyanEMC
issue.Thisisverylikelyifthe
