Selection of operation mode and operation location
(2) Selects the command source of the PU operation mode (Pr. 551)
Any of the operation panel, PU connector, or USB connector can be specified as the command source in the PU operation
mode.
In the PU operation mode, set Pr. 551 to "2" when executing parameter write, start command or frequency command
during the RS-485 communication with PU communication.
NOTE
When performing the RS-485 communication with the PU connector when Pr. 551 = "9999", PU mode command
source does not automatically change to the PU connector. Change to the Network operation mode to change the
command source.
When "2" (NET mode PU connector) is set in Pr. 550 and "2" (PU mode PU connector) is set in Pr, 551, PU operation
mode has priority. When the communication option is not fitted, therefore, the operation mode cannot be switched to
the Network operation mode.
Changed setting value is valid when powering on or resetting the inverter.
The Modbus-RTU protocol cannot be used in the PU operation mode. Select Network operation mode (NET mode
command source).
