Appendix A – Fieldbus control
316
The fieldbus control interface
The 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 12
data words (16-bit) in each direction.
Data transmitted from the drive to the fieldbus controller is defined by parameters
52.01 … 52.12 (FBA DATA IN) and data transmitted from the fieldbus controller to the
drive is defined by parameters 53.01 … 53.12 (FBA DATA OUT).
The Control Word and the Status Word
The Control Word (CW) is the principal means of controlling the drive from a fieldbus
system. The Control Word is sent by the fieldbus controller to the drive. The drive
switches between its states according to the bit-coded instructions of the Control
Word.

1) See also other parameters which can be controlled by the fieldbus.
2) The maximum number of used data words is protocol-dependent.
3) Profile/instance selection parameters. Fieldbus module specific parameters. For more information, see the
User’s Manual of the appropriate fieldbus adapter module.
4) With DeviceNet the control part is transmitted directly.
5) With DeviceNet the actual value part is transmitted directly.
