The inverter needs frequency command and start command. Refer to the flow chart below to
perform setting.
Check the following items before powering on the inverter:
●
Check that the inverter is installed correctly in a correct place. (Refer to section 2.3.)
●
Check that wiring is correct. (Refer to section 3.2.)
●
Check that no load is connected to the motor.
