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
