FUNCTIONS
2.5 Operation Mode Setting of the Inverter
2.5.1 Operation mode setting
For operating the inverter using FR Configurator (parameter change, auto tuning and test operation, etc.), the operation mode
of inverter must be set. Refer to the table, and select an operation mode, which matches to each connecting method. The
selection of operation mode can be made using the tool bar. (Refer to page 18)
* When connecting a USB connector, set "3" in Pr.551 PU mode control source selection. The change for the setting value of Pr.551 becomes valid when turning on
the power next time or resetting the inverter.
