●
At the initial setting (Pr. 551 "PU mode operation command source selection" = "9999"), commu-
nication with FR Configurator2 can be made in the PU operation mode simply by connecting a
USB cable. To fix the command source to the USB connector in the PU operation mode, set "3" to
Pr. 551.

Parameter setting and monitoring can be performed by FR Configurator2. For details, refer to the
Instruction Manual of FR Configurator2.
5.15.11 Automatic connection with GOT
When the automatic connection is enabled in the GOT2000 series, the inverter can communicate with
the GOT only setting the station number and connecting the GOT. This eliminates the need for the
communication parameter setting.
When Pr. 549 "Protocol selection" = "1" (Modbus® RTU protocol), the setting range is as shown in
the parentheses.
When the set value is outside of the setting range, the initial value is applied.
