Preparing for Operation
Chapter 4
4-1 Preparation Procedure
1. Installation:
Install the Inverter according to installation conditions. Refer to page 3-2.
Check that all the installation conditions are met.
2. Wiring:
Connect the Inverter to power supply and peripheral devices. Refer to page 3-7.
Select peripheral devices that meet the specifications, and wire them correctly.
3. Turning the Power On:
Check the necessary items, then turn the power on.
Always check that the power voltage is correct and the power input terminals (R, S,
and T) are wired correctly.
SPower voltage
200-VAC class:
400-VAC class:
Three-phase, 200 to 230 VAC, 50/60 Hz
Three-phase, 380 to 460 VAC, 50/60 Hz
When a 3G3EV-ABjjj is used in single-phase input mode, the power voltage
must be as follows: single-phase, 200 to 240 VAC, 50/60 Hz (use terminals R and
S)
Check that the motor output terminals (U, V, and W) and motor are connected cor-
rectly.
Check that the control circuit terminals and controller are connected correctly.
4. Checking Display Status:
Check the Inverter for errors.
If everything is normal, the indicators below become as follows when the power is
turned on:
SRUN indicator: Flashing
SALARM indicator: Not lit
SConstant item indicators: “FREF,” “FOUT,” or “IOUT” is lit.
SData display: Data corresponding to the constant item indicators is displayed.
If an error exists, the ALARM indicator lights up. In this case, take the necessary ac-
tion as described in Section 5 Operation.
5. Setting Constants:
Use the Digital Operator to set constants required for operation. Refer to page 4-3.
Specify each constant as described in this manual.
