282 Fieldbus control
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 bits) in each direction.
Data transmitted from the drive to the fieldbus controller is defined by parameters
52.01 FBA data in1 … 52.12 FBA data in12 . The data transmitted from the fieldbus
controller to the drive is defined by parameters 53.01 FBA data out1 … 53.12 FBA
data out12 .

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.
