344 Control through a fieldbus adapterBasics of the fieldbus adapter interfaceThe cyclic communication between a fieldbus system and the drive consists of 16/32-bit input and output data words. The drive supports at the maximum the use of 12data words (16 bits) in each direction.Data transmitted from the drive to the fieldbus controller is defined by parameters52.01 FBA data in1 … 52.12 FBA data in12.
