About this manual
This manual is intended to be used both as an
instructional and as a reference manual. It only briefly
touches on the basics of the PROFIBUS protocol
whenever it is necessary for gaining an understanding
of the PROFIDRIVE implementation of the PROFIBUS
Profile for Variable Speed Drives (VDI/VDE 3689) and
the DANFOSS PROFIBUS for the FC motor and the
VLT 2800.
The manual is also intended to serve as a guideline
when you specify and optimize your communication
system.
If you are not completely familiar with PROFIBUS or
the Profile for Variable Speed Drives, it may be
advisable to read some of the material provided on
these subjects, eg DIN 19245 parts 1 and 3 and VDI/
VDE 3689.
Even if you are an experienced PROFIBUS
programmer, we suggest that you read this manual in
its entirety before you start programming, since
important information can be found in all chapters.

Assumptions
This manual assumes that you are using a DANFOSS
FCM 300 and VLT 2800 with PROFIBUS. It is also
assumed that you, as a master, are using a PLC or
PC that is equipped with a serial communication card
supporting all the PROFIBUS communication services
required by your application, and that all
requirements stipulated in the PROFIBUS standard as
well as those set up in the PROFIBUS Variable Speed
Drives Profile and its company-specific
implementation PROFIDRIVE, as well as those
pertaining to the VLT Variable Speed Drive are strictly
observed as well as all limitations therein fully
respected.
What you should already know
The DANFOSS PROFIBUS is designed to
communicate with any master abiding by the
PROFIBUS DP standard. It is therefore assumed that
you have full knowledge of the PC or PLC you intend
to use as a master in your system. Any questions
pertaining to hardware or software produced by any
other manufacturer is beyond the scope of this
manual and is of no concern to DANFOSS.
If you have questions about how to set up master -
master communication or communication to a non-
Danfoss slave, the appropriate manuals should be
consulted.
