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:
(The operating procedure below is common to the standard and optional digital operators.)
3-phase
power supply
Default jumper position for sinking type inputs
(Altanatively, CM1-PLC for souricing tiype)
(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
(The monitor shows a 2-digit numeric value.)
- Use the 1 and/or
key once to specify the digital operator as the operating device to input frequency-setting
STR
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
(The monitor shows a 2-digit numeric value.)
- Use the and/or
1
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
(The monitor shows a preset output frequency. With the factory setting,
- Use the and/or
1
and then press the
(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
(The monitor shows "00" or "01".)
