Integrating inverters into PROFIBUS
Procedure
To connect the inverter to a control via PROFIBUS DP, proceed as follows:
1. Integrate the inverter into the bus system (e.g. line topology) of the control using
PROFIBUS cables via socket X126.
The position of the sockets and the pin assignment can be found in Section Overview of
the interfaces (Page 82).
The maximum permitted cable length to the previous station and the subsequent one is
100 m at a baud rate of 12 Mbit/s.
2. Externally supply the inverter with 24 V DC through terminals 31 and 32.
The external 24 V supply is only required if communications with the control should also
run when the line voltage is switched off.
You have now connected the inverter to the control using PROFIBUS DP.
Configuring the communication using SIMATIC S7 control
● If the inverter is listed in the hardware library of HW-Conifg, you can configure the
communication in the SIMATIC control.
● If the inverter is not listed in the hardware library, you can either install the newest
STARTER version or install the GSD of the inverter through "Extras/GSD-Install file" in
HW-Config. See also GSD
(http://support.automation.siemens.com/WW/view/en/22339653/133100).
When you have installed the GSD, configure the communication in the SIMATIC control.
Setting the address
Valid address range: 1 ... 125
The positions of the address switches are described in Section: Overview of the interfaces
(Page 82).
Converter with CU230P-2 Control Units
Operating Instructions, 04/2015, FW V4.7 SP3, A5E34257946B AB
You set the PROFIBUS address of the inverter using
the address switch on the Control Unit, in parameter
p0918 or in STARTER.
In parameter p0918 (factory setting: 126) or in
STARTER, you can only set the address, if all address
switches are set to "OFF" (0) or "ON" (1).
If you have specified a valid address with the address
switches, this address will always be the one that
takes effect and parameter p0918 cannot be changed.
