Setting the address

You set the PROFIBUS address of the inverter using
the address switch on the Control Unit, using
parameter p0918 or in STARTER.
Using parameter p0918 (factory setting: 126) or using
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 using the
address switches, this address will always be the one
that takes effect and parameter p0918 cannot be
changed.
Valid address range: 1 ... 125
The positions of the address switches are described
in Section: Overview of the interfaces (Page 56).
Procedure
To change the bus address, proceed as follows:
1. Set the address using one of the subsequently listed options:
– using the address switches
– with an operator panel using p0918
2. Switch on the inverter power supply and, if being used, the 24 V supply
for the Control Unit.
3. Switch on the voltages again after all LEDs at the inverter have gone dark.
This means that you have changed the bus address.
