• 12M bits/s (MVS3007-4002 PROFIBUS board only)
2.1.2 PROFIBUS Protocol
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.
