E6581611F-13966.38.2 Using RS485■ Communication function settingsCommands and frequency settings are given priority by communication. (Prioritized by commands from thepanel or terminal block.) Thus, command and frequency settings from communication are activated,regardless of the command mode selection (cmod) or frequency settings mode selection settings (fmod).However, setting 48: SCLC (switching from communication to local) with input terminal function selection andwhen inputting from an external device, it is possible to operate at command mode selection (cmod) andfrequency setting mode selection (fmod) settings.Moreover, selecting local mode with the EASY key as Local / remote key function changes to panelfrequency/panel operation mode.■ Transmission specificationsItem SpecificationsCommunication protocol TOSHIBA inverter protocol MODBUS-RTUprotocolInterface RS485 compliantTransmission scheme Half duplex [Serial bus type (Line terminations resistor necessary atboth ends of system)]Wiring 2-wireTransmission distance 500 m max.
