Preparation Procedure - Omron SYSDRIVE 3G3EV SERIES User Manual

4-1 Preparation Procedure

1. Installation:
Install the Inverter according to installation conditions.
Check that all the installation conditions are met.
2. Wiring:
Connect the Inverter to power supply and peripheral devices.
Select peripheral devices that meet the specifications, and wire them correctly. Set
and end unit as necessary.
3. Testing the Inverter Only
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.
Power voltage
Three-phase, 200 to 230 VAC, 50/60 Hz
When a 3G3EV-AB
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.
Checking Display Status:
Check the Inverter for errors.
If everything is normal, the indicators below become as follows when the power is
turned on:
RUN indicator: Flashing
ALARM indicator: Not lit
Setting Constants:
Use the Digital Operator to set constants required for operation.
Set each constant as described in this manual. Set these constants in the following
order:
a) n01 and n02 (initializing constants)
b) n24 to n26 (V/f pattern)
is used in single-phase input mode, the power voltage
