(Operating procedure)
1) Confirm that all wirings are correct.
2) Turn on the earth-leakage breaker (ELB) to supply power to the inverter.
(The POWER lamp [red LED] of the digital operator goes on.)
3) Select the control circuit terminal block as the device to input frequency-setting commands by the
frequency source setting function.
- Display the function code "A001" on the monitor screen, and then press the
(The monitor shows a 2-digit numeric value.)
- Use the 1 and/or
key once to specify the control circuit terminal block as the device to input frequency-setting
STR
commands.
(The display reverts to [A001].)
4) Select the control circuit terminal block as the device to input operation commands by the run
command source setting function.
- Display the function code "A002" on the monitor screen, and then press the
(The monitor shows a 2-digit numeric value.)
- Use the and/or
1
key once to specify the digital operator as the device to input operation commands.

6) Start the motor operation.
- Set the FW signal (at the FW terminal on the control terminal block) to the ON level to start the
motor.
(The RUN lamp [green LED] goes on.)
- Apply a voltage across the terminals O and L on the control circuit block to output the frequency
corresponding to the applied voltage from the inverter.
7) Stop the motor.
- Set the FW signal (at the FW terminal on the control terminal block) to the OFF level to decelerate
and stop the motor.
(When the motor stops, the RUN lamp [green LED] goes off.)
