Powerup Test

Step 9: After wiring the inverter and motor, you’re ready to do a powerup test. The

9 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 motor.

No additional wiring of inverter connectors or terminals has been done.

The power supply is reliable, and the motor is a known working unit.

The motor is securely mounted, and is not connected to any load.

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.Give a brief introduction to the use of the built-in operator keypad.

The powerup test gives you an important starting point to ensure a safe and successful application of the Hitachi inverter. We highly recommend performing this test before proceeding to the other chapters in this manual.

Pre-test and Operational Precautions

and Installation

Inverter Mounting

 

 

The following instructions apply to the powerup test, or to any time the inverter is powered and operating. Please study the following instructions and messages 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 cut-off switch for the drive input power if necessary. However, do not turn off power to the inverter during its operation unless it is an emergency.

3.Turn the inverter’s front panel potentiometer to the MIN position (fully counter-clock- wise).

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 check the capability and limitations of the motor and machine before operating the inverter. Otherwise, there is the danger of injury.
