Configuring the fieldbus
7.2 Communication via PROFIBUS
Inverter with CU230P-2 Control Units
114 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
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.
Valid address range: 1 … 125
of the address switches are described
Interfaces, connectors, switches, control
terminals, LEDs on the CU (Page 60).
To change the bus address, proceed as follows:
1. Set the new address:
– using the address switches
– from an operator panel in parameter p0918
– in STARTER using screen form "Control Unit/Communication/PROFIBUS", or using
the expert list in parameter p0918
2. Switch on the inverter power supply and, if available, the 24 V power supply for the
Control Unit.
3. Switch on the voltages again after all LEDs at the inverter have gone dark.
You have so changed the bus address.
