Implements the PROFIBUS-DP Fieldbus protocol according to DIN
19245.
2.1.3 Data Refresh Rate
Data is exchanged between the PROFIBUS Fieldbus module and
the drive's parameters every 10ms.
2.1.4 MVS3007-4001 board Data Volume
Cyclic Channel Receive:
•
1 control word (16 bit), and
•
5 reference demands (16 bit),
or,
•
2 control words (16 bit), and
•
4 reference demands. (16 bit).

If at any time the baud rate is changed in the PROFIBUS-DP master then it is
necessary to power cycle the drive for the change to be recognised by this module.
