Test Run

4-1 Procedure for Test Run

1. Installation and Mounting
Install the Inverter according to the installation conditions. Refer to page 2-2. Ensure
that the installation conditions are met.
2. Wiring and Connection
Connect to the power supply and peripheral devices. Refer to page 2-7. Select
peripheral devices which meet the specifications and wire correctly.
3. Power Connection
Carry out the following pre-connection checks before turning on the power supply.
Always ensure that a power supply to the correct voltage is used and that the power
input terminals (R/L1, S/L2, and T/L3) are wired correctly.
3G3JV-A2 : 3-phase 200 to 230 VAC
3G3JV-AB : Single-phase 200 to 240 VAC (Wire R/L1 and S/L2)
Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are connected to
the motor correctly.
Ensure that the control circuit terminals and the control device are wired correctly.
Make sure that all control terminals are turned off.
Set the motor to no-load status (i.e., not connected to the mechanical system).
Having conducted the above checks, connect the power supply.
4. Check the Display Status
Check to be sure that there are no faults in the Inverter.
If the display at the time the power is connected is normal, it will read as follows:
RUN indicator: Flashes
ALARM indicator: Off
Setting/Monitor indicators: FREF, FOUT, or IOUT is lit.
Data display: Displays the corresponding data of the indicator that is lit.
When a fault has occurred, the details of the fault will be displayed. In that case,
refer to Chapter 7 Maintenance Operations and take necessary remedies.
5. Initializing Parameters
Initialize the parameters.
Set n01 to 8 for initialization in 2-wire sequence.
6. Setting Parameters
Set the parameters required for a test run.
Set the rated motor current in order to prevent the motor from burning due to over-
loading.
