Fieldbus control through a fieldbus adapter 251
Basics of the fieldbus control interface
The cyclic communication between a fieldbus system and the drive consists of 16- or
32-bit input and output data words. The drive is able to support a maximum of 12 data
words (16 bits) in each direction.
Data transmitted from the drive to the fieldbus controller is defined by parameters
52.01 FBA A data in1 … 52.12 FBA A data in12. The data transmitted from the
fieldbus controller to the drive is defined by parameters 53.01 FBA A data out1 53.12
FBA A data out12.
