DESCRIPTION
1.1

Technical data

PROFIBUS is contained within the cover of the Options module attached to the
side of the inverter. The PROFIBUS unit is powered directly from the inverter and
therefore needs no additional external supply during normal operation. Provision
exists on PROFIBUS for the connection of an external control supply, which can be
used to apply power to the Inverter control circuits.
The board is connected to the PROFIBUS system via an 11 – way Communication
Interface connector. All connections to this RS485 interface are short-circuit-proof
and isolated.
1.2

Functionality

Ø Cyclical process data exchange (PZD) in accordance with PROFIDrive Profile,
version 2.0 or version 3.0
Ø Parameter accessing:
Cyclical accessing of parameters (PKW) in accordance with PROFIDrive
Profile version 2.0
or
Acyclical accessing of parameters (data block 47) in accordance with
PROFIDrive Profile version 3.0
Ø Acyclical accessing of parameters (data block 100/data block 47) for the
purpose of exchanging parameter values with a SIMATIC S7 CPU
(Drive ES SIMATIC function block package)
Ø Acyclical accessing of parameters for SIMATIC HMI or SIEMENS Drive
STARTER tool.
Ø Support of PROFIBUS control commands SYNC and FREEZE for
synchronized data transfer between the master and several slaves
Ø Internode communication for direct exchange of process data between
PROFIBUS slaves (only in conjunction with SIMATIC S7 at the present time).
