3.3 How To Make a Test Run

This section describes how to make a test run of the inverter that is wired and connected to external devices in a general way as shown below.

For the detailed method of using the digital operator, see Section 3.2, "How To Operate the Digital Operator."

(1)When entering operation and frequency-setting commands from the digital operator:

(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.)

*When using an inverter with the factory setting, proceed to step 5).

3)Select the digital operator as the operating device via the frequency source setting function. - Display the function code "A001" on the monitor screen, and then press the FUNC key once.

(The monitor shows a 2-digit numeric value.)

- Use the 1 and/or 2 key to change the displayed numeric value to [02], and then press the STR key once to specify the digital operator as the operating device to input frequency-setting

commands.

(The display reverts to [A001].)

4)Select the digital operator as the operating device by the run command source setting function. - Display the function code "A002" on the monitor screen, and then press the FUNC key once.

(The monitor shows a 2-digit numeric value.)

- Use the 1 and/or 2 key to change the displayed numeric value to "02", and then press the STR key once to specify the digital operator as the operating device to input operation commands.

(The display reverts to [A002]. The operating device indicator lamp above the [RUN] key goes on.)

5)Set the output frequency.

- Display the function code "F001" on the monitor screen, and then press the FUNC key once.

(The monitor shows a preset output frequency. With the factory setting,		[0 Hz] is shown.)
- Use the 1 and/or	2 key to change the displayed numeric value to the desired output frequency,
and then press the STR	key once to determine the frequency.
(The display reverts to [F001].)
6) Set the operation direction of the motor.
- Display the function code "F004" on the monitor screen, and then press the FUNC		key once.
(The monitor shows "00" or "01".)
