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.

NOTES
When protecting the motor from overheat by the inverter, set Pr. 9 "Electronic thermal O/L relay".
(Refer to section 5.1.1.)
When the rated frequency of the motor is 60 Hz, set Pr. 3 "Base frequency" (Refer to section 5.1.2.)

How
to give a start
command?
Start command using the PU connector and plug-in
option (communication). (Refer to section 3.5.3.)
Start command with
RUN on the operation
panel (PU).
How to
give a frequency
