Mitsubishi Electric FR-E700 Instruction Manual page 376

Selection of operation mode and operation location
Selects the command source of the PU operation mode (Pr. 551)
Any of the operation panel, PU connector, Ethernet connector (only FR-E700 SC ENE), or USB connec-
tor 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 fre-
quency command during the RS-485 communication with PU communication.
NOTES 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 net-
work 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 for the FR-E700
SC EC, therefore, the operation mode cannot be switched to the network operation mode.
Changed setting value is made 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).
All of the operation mode indicator (
thecommand source for the FR-E700 SC EC is not the operation panel.

The Modbus®-RTU protocol cannot be used in the PU operation mode. When using the Mod-
bus®-RTU protocol, set Pr. 550 to "2".
For FR-E700 SC EC: When the communication option is not fitted, the operation mode cannot be
switched to the network operation mode.
When Pr. 551 = "9999", the priorities of the PU control source is USB connector > parameter unit
(FR-PU04/FR-PU07) > operation panel.
