Connection and Parameter Setting
(1) Related parameter for connection of multiple inverters through GOT
Check a connection between the inverter and GOT, and set the following communication parameter when connecting
through GOT.
When performing parameter writing or run command input, set the following command source parameters, and switch
the operation mode to the following operation mode.
*1 Depending on the production year and month of FR-A700, the setting range and initial value of Pr. 551 may differ. For the details, refer to the Appendices of the
Instruction Manual of the inverter.
*2 FR-E700-SC/NC are not compatible with FR-E7TR.
