Setting the address
You set the MAC address of the inverter using the
address switches on the Control Unit, using parame-
ter p2021 or in STARTER.
Valid address range: 0 ... 127, as the inverter in
BACnet is considered as master.
For address 0, the inverter responds to a broadcast.
If you have specified a valid address ≠ 0 using the
address switches, this address will always be the one
that takes effect and parameter p2021 cannot be
changed.
The position of the address switches can be found in
the operating instructions of the Control Unit in the
section "Overview of interfaces".
Procedure
To change the bus address, proceed as follows:
1. Set the new address:
– using the address switches
– from an operator panel in parameter p2021
– in STARTER using screen form "Control Unit/Communication/Fieldbus", or using the
2. Switch off the inverter supply voltage.
3. Wait until all LEDs on the inverter go dark.
4. Switch on the inverter supply voltage again.
Your settings become active after switching on.
You have so changed the bus address.
