P2021 Modbus address 1 - 247 1 T - - U16 2
Sets unique address for inverter.
P2022 Modbus reply timeout
[ms]
0 - 10000 1000 U, T - - U16 3
The time in which the inverter is allowed to respond to the Modbus master. If the forming of a response
needs more time than specified in this parameter, the processing is done, but no response is sent.
P2023 RS485 protocol selection 0 - 2 1 T - - U16 1
Select the protocol which runs on the RS485 link.
0 None
1 USS
2 Modbus
Notice: After changing P2023, powercycle the inverter. During the powercycle, wait until LED has gone off or the
display has gone blank (may take a few seconds) before re-applying power. If P2023 has been changed
via a PLC, make sure the change has been saved to EEPROM via P0971.
