Mitsubishi Electric FR-F800 Series Instruction Manual page 253

NOTE
• 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 this reason, if the communication option is not mounted, switching to the Network operation mode is no
longer possible.
• Changed setting values are enabled at power-ON or inverter reset.
