1.2 Step of operation
The inverter needs frequency command and start command. Frequency command (set frequency) determines the
rotation speed of the motor. Turning ON the start command starts the motor to rotate.
Refer to the flow chart below to perform setting.
·When protecting the motor from overheat by the inverter, set Pr.9 Electronic thermal O/L relay (Refer to
page 52)
·To drive a general-purpose motor with the rated motor frequency of 50Hz, set Pr.3 Base frequency
(Refer to page 53)
CAUTION
Check the following points before powering ON the inverter.
· Check that the inverter is installed correctly in a correct place. (Refer to page 8)
· Check that wiring is correct. (Refer to page 9)
· Check that no load is connected to the motor.
Connect a switch, relay, etc.
