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 instal-
lation conditions are met.
2. Wiring and Connection
Connect to the power supply and peripheral devices. Refer to page 2-11. 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.
S 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.
3G3MV-A2j: 3-phase 200 to 230 V AC
3G3MV-ABj: Single-phase 200 to 240 V AC (Wire R/L1 and S/L2)
3G3MV-A4j: 3-phase 380 to 460 V AC
S Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are connected to the motor
correctly.
S Ensure that the control circuit terminals and the control device are wired correctly. Make sure that
all control terminals are turned OFF.
Note Set parameter n052 (terminal S3) to 0 if a 3-wire sequence is set.
S Set the motor to no-load status (i.e., not connected to the mechanical system).
S 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.
S If the display at the time the power is connected is normal, it will read as follows:
RUN indicator: Flashes
ALARM indicator: OFF
Simplified-LED (setting/monitor) indicators: FREF, FOUT, or IOUT is lit.
Data display: Displays the corresponding data of the indicator that is lit.
S When a fault has occurred, the details of the fault will be displayed. In that case, refer to Chapter 8
Maintenance Operations and take necessary remedies.
5. Initializing Parameters
Initialize the parameters.
S Set n001 to 8 for initialization in 2-wire sequence.
6. Setting Parameters
Set the parameters required for a test run.
S Perform the test run in V/f control mode. The control mode needs to be set to V/f control since it will
not be initialized. Set the rated motor current in order to prevent the motor from burning due to
overloading.
