Setting the address
Valid address area: 1 … 99
You have the following options for setting the address:
● Using the address switch on the Control Unit:
Figure 5-13 Address switch with example for bus address 10
The address switch has priority over the other settings.
● Using Startdrive or an operator panel via parameter p2021 (default setting: p2021 = 99).
It is only possible to change p2021 if an invalid address is set in the address switch.
If you are working with Startdrive, back up the settings so they are not lost if the power
fails.
You can find the position of the address switch in the operating instructions for the inverter.
