Important Notes
●Read this User Manual carefully before you start installation and commissioning work on
MOVITRAC®frequency inverters with fieldbus options.
This User Manual assumes that the user is familiar with and has at his disposal all relevant
documentation on the MOVITRAC®system, particularly the Installation and Operating
Instructions.
●Safety notes:
Always follow the safety notes contained in this User Manual.
Safety notes are marked as follows:
Electrical hazard, e.g. during live working
Mechanical hazard, e.g. when working on hoists
Important instructions for the safe and fault-free operation of the system, e.g.
presetting before commissioning.
Failure to follow these instructions may result in injury to people and damage to
property.
●General safety notes for bus systems:
The fieldbus option gives you a communications system which allows you to match the
MOVITRAC®31.. drive system to the specifics of your application to a very high degree. As
with all bus systems there is, however, the risk of parameters being changed, which will not
show outside (i.e. the inverter) but affect the behaviour of the inverter. This may result in
unexpected (not uncontrolled, though) system behaviour.
●In these instructions, cross-references are marked with a →, e.g.,
(→MC_SHELL) means: Please refer to the MC_SHELL User Manual for detailed information or
information on how to carry out this instruction.
(→section x.x) means: Further information can be found in section x.x of this User Manual.
●Each unit is manufactured and tested to current SEW-EURODRIVE technical standards and
specifications.
The manufacturer reserves the right to make changes to the technical data and designs as well
as the user interface herein described, which are in the interest of technical progress.
A requirement for fault-free operation and fulfilment of any rights to claim under guarantee is that
these instructions and notes are followed.
These instructions contain important information for servicing, they should therefore be kept in
the vicinity of the unit.

Preface
This
Fieldbus Unit Profile Manual describes the operation of the MOVITRAC®31.. frequency inverter
when connected to a higher-level automation system via a fieldbus option pcb. In addition to
descriptions of all the fieldbus parameters, the various control concepts and potential applications
are dealt with in the form of brief examples of programs. The application examples are described
both in graphic form as well as in Simatic-S5 syntax. These application examples can be used with
almost all fieldbus option pcbs that fit the MOVITRAC®31.. inverter.
In addition to this Fieldbus Unit Profile User Manual, the following more detailed documentation on
fieldbus is also necessary in order to enable the MOVITRAC®31.. to be connected simply and
efficiently to the fieldbus system (e.g. PROFIBUS-DP, PROFIBUS-FMS, INTERBUS-S, etc.):
– User Manual for PROFIBUS (FFP 31..) option, part number 0922 6818
– User Manual for INTERBUS-S (FFI 31..) option, part number 0922 6915
– User Manual Communications Interfaces and Parameter List MOVITRAC®31..,
part number 0923 0580
The FFP 31.. PROFIBUS Option PCB User Manual describes the installation and commissioning of
the FFP 31.. PROFIBUS option pcb and gives further examples of applications specifically for setting
the inverter parameters via PROFIBUS-DP and PROFIBUS-FMS.
The FFI 31.. INTERBUS Option PCB User Manual describes the installation and commissioning of the
FFI 31.. INTERBUS-S option pcb and gives further examples of applications specifically for setting
the inverter parameters via INTERBUS-S.
The MOVITRAC®31.. Parameter List contains a list of all the inverter’s parameters that can be read
or written via the various communication interfaces such as the RS-232, RS-483 and via the fieldbus
interface.
