Operation Mode Selection - Mitsubishi Electric 800 Series Instruction Manual

5.9.1

Operation mode selection

Select the operation mode of the inverter.
The mode can be changed among operations using external signals (External operation), operation by the operation
panel or the parameter unit (PU operation), combined operation of PU operation and External operation (External/PU
combined operation), and Network operation (when RS-485 terminals or a communication option is used).
