4.2 Drive the motor
The inverter needs frequency command and start command. Refer to the flow chart below to perform
setting.
Frequency [Hz]
Start command
Set from the operation
panel and the PU
(FR-PU04/FR-PU07).
(Refer to page 5-20)
Fig. 4-5:
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 60Hz, set Pr. 3 "Base frequency" (Refer to section 5.1.2.)
