Mitsubishi Electric FR-F820-00077 Instruction Manual page 303

Parameters
Selection of command source in Network (NET) operation mode (Pr. 550)
● Either of the RS-485 terminals or the communication option can be specified for the command
source in the Network operation mode.
For FR-F800-E: Either of the Ethernet connector or the communication option can be specified for
the command source in the Network operation mode.
● For example, whether or not the communication option is mounted, set Pr. 550 = "1" to write
parameters from or input the start and frequency commands via RS-485 terminals in the Network
operation mode.
For FR-F800-E: Whether or not the communication option is mounted, set Pr. 550 = "5" to write
parameters or input the start and frequency commands via the Ethernet connector in the Network
operation mode.
NOTE In the initial setting, "9999" (communication option automatic recognition) is set for Pr. 550. Thus,
if the communication option is mounted, parameters cannot be written or the start and frequency
commands cannot be sent by communications that use the RS-485 terminals (or the Ethernet con-
nector for FR-F800-E). (Monitoring or parameter reading can be performed.)
Selection of the command source of the PU operation mode (Pr. 551)
● Any of the PU connector, the RS-485 terminals, the Ethernet connector (for FR-F800-E), or USB
connector can be specified as the command source in the PU operation mode.
● Set Pr. 551="1" to use communication connected to the RS-485 terminals to write parameters or
execute start and frequency commands in the PU operation mode. Set Pr. 551 = "3" or "9999" to
use the USB connector.
For FR-F800-E: In the PU operation mode, set Pr. 551 = "5" to write parameters or input the start
and frequency commands via the Ethernet connector.
NOTES When Pr. 550 = "1" (NET mode RS-485 terminals) and Pr. 551 = "1" (PU mode RS-485 terminals), the
PU operation mode has a precedence.
For FR-F800-E: When Pr. 550 = "5" (NET operation mode, Ethernet connector) and Pr. 551 = "5" (PU
operation mode, Ethernet connector), the PU operation mode has precedence.
For this reason, if the communication option is not mounted, switching to the Network operation
mode is not longer possible.
Changed setting values are enabled at power-ON or inverter reset.
