Signal pattern, LD output circuit
Note
The logic status of signals A and B is not defined regarding the reference signal RD or R. It may deviate from the signal pattern.
Note
Reference 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.
