A1.6.3 Configuration of the armature current feedback circuit
Overview
Thecurrentfeedbacksignalissenttothecontrolunitbytwocurrenttransducers(CT)insertedonphasesUand
Wofthecontrolledpowerbridge.ItisrectiedontheFIRXP-XXcardbyathree-phasediodebridgeandap-
pliedtoaburdenresistorthatconvertsitintoavoltagesignalproportionaltotheDCmotorcurrentvalue.This
isthenappliedtothearmaturecurrentregulatorwhichcomparesitwiththereferencevalue.
ThestandardFIRXP-XXcardoffersachoiceoftwoburdenresistor(RB)values,2.5Ohmor5Ohm,which
aresuitableinthemajorityofcases.Otherwiseanexternalburdenresistorcanbeused,connectedbetween
terminalsRCTand0VI.
Inordertoenablepreciseadjustmenttothemanypossibleratedcurrentvalues(sizeofthecontrolledpower
bridge),aprogrammablegainamplier(N8)isinsertedbetweentheburdenresistorandthecurrentregulator.
Thegainissetbymeansofa12-bitbinarynumberselectedwithdip-switchesS3andS4.
