HintThe logic status of signals A and B is not defined regarding the reference signal FRD or FR. It may deviate from the signal pattern.

HintReference or index signal with 4 increments (360°) signal length is only valid from the 5th counting step onwards. A corresponding delay should be taken into consideration after switching on the operating voltage.
