2-4 Powerup Test
Step 6 After wiring the inverter and motor, you're ready to do a powerup test. The
procedure that follows is designed for the first-time use of the drive. Please
verify the following conditions before conducting the powerup test:
• You have followed all the steps in this chapter up to this step.
• The inverter is new, and is securely mounted to a non-flammable vertical
surface.
• The inverter is connected to a power source and a motor.
• No additional wiring of the inverter connectors or terminals has been
done.
• The power supply is reliable, and the motor is a known working unit, and
the motor nameplate ratings match the inverter ratings.
• The motor is securely mounted, and is not connected to any load.
2-4-1 Goals for the Powerup Test
If there are any exceptions to the above conditions at this step, please take a
moment to take any measures necessary to reach this basic starting point.
The specific goals of this powerup test are:
1. Verify that the wiring to the power supply and motor is correct.
2. Demonstrate that the inverter and motor are generally compatible.
3. Get an introduction to the use of the built-in operator keypad.
The powerup test gives you an important starting to ensure a safe and suc-
cessful application of the Omron inverter. We highly recommend performing
this test before proceeding to the other chapters in this manual.
2-4-2 Pre-test and Operational Precautions
The following instructions apply to the powerup test, or to any time the inverter
is powered and operating. Please study the following instructions and mes-
sages before proceeding with the powerup test.
1. The power supply must have fusing suitable for the load. Check the fuse
size chart presented in Step 5, if necessary.
2. Be sure you have access to a disconnect switch for the drive input power
if necessary. However, do not turn OFF power during inverter operation un-
less it is an emergency.
!Caution The heat sink fins will have a high temperature. Be careful not to touch them.
Otherwise, there is the danger of getting burned.
!Caution The operation of the inverter can be easily changed from low speed to high
speed. Be sure to check the capability and limitations of the motor and
machine before operating the inverter. Otherwise, there is the danger of injury.
!Caution If you operate a motor at a frequency higher than the inverter standard default
setting (50 Hz/60 Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequen-
cies after getting their approval. Otherwise, there is the danger of equipment
damage and/or injury.
