3 DRIVE THE MOTOR

3.1 Step of operation
The inverter needs frequency command and start command. Turning the start command on
start the motor rotating and the motor speed is determined by the frequency command (set
frequency).
Refer to the flow chart below to perform setting.

CAUTION
Check the following items before powering on the inverter.
· Check that the inverter is installed correctly in a correct place. (Refer to page 7)
· Check that wiring is correct. (Refer to page 8)
· Check that no load is connected to the motor.
·When protecting the motor from overheat by the inverter, set Pr.9 Electronic thermal O/L relay (Refer to
page 48)
· When the rated frequency of the motor is 50Hz, set Pr.3 Base frequency (Refer to page 49)
