Fieldbus control description

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).

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.
