6.1.2
Setting the address
You can set the inverter's PROFIBUS address using either DIP switches on the Control Unit
or parameter p0918.
Valid PROFIBUS addresses:
1 … 125
Invalid PROFIBUS addresses:
0, 126, 127
If you have specified a valid address using DIP switches, this address will always be the one
that takes effect and p0918 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then p0918 defines the address.
The positions and settings of the DIP switches are described in Section: Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
CAUTION
A bus address that has been changed is only effective after the inverter has been switched
off and back on again.
