SMC3_PersistPosition (FB)¶

FUNCTION_BLOCK SMC3_PersistPosition

This function block serves to persist the axis position of a multi-turn absolute encoder with real axis.

This function block assumes that the multi-turn encoder has a range of 2^32. For multi-turn encoders with a smaller range, please use SMC3_PersistPositionSingleturn.
