4.4 Running the Inverter for Motor Operation Check

After preparations of 4.1-4.3 have been completed, begin to perform the test drive of the motor.

Turn on both terminals [EN1] and [EN2] before running the motor.

If terminal

s [EN1] or [EN2] and [PLC] are not connected, the motor doesn’t rotate.

------------------------------- Test Run Procedure using the multi-function keypad (option) ------------------------------

(1) Turn the power ON and check that the LCD monitor blink while indicating a reference speed of 0.00.

(2) Enter the local mode by holding down the

key for at least 2 seconds. Pressing this key toggles between

Local mode and Remote mode.

(3) Select a low reference speed (safety speed) by using the

/ Key. Be sure of that the reference speed

blinks on the LCD monitor.

(4) Press the

key to start running the motor in the forward direction. Check that the reference speed is

displayed on the LCD monitor correctly. Also check whether the motor rotating direction is correct.

(5) To stop the motor, press the key.

(6) Press the

key to start running the motor in the reverse direction. Check that the reference speed is

displayed on the LCD monitor correctly. Also check whether the motor rotating direction is correct.

(7) To stop the motor, press the key.

When turning the power OFF and ON again, the inverter returns to Remote mode.

< Check the following points >

・Pressing the key runs the motor forward.

・Pressing the key runs the motor reverse.

・Check for smooth rotation without motor humming or excessive vibration.

4.5 Preparation for Practical Operation

After confirming correct operation by performing a test run, make mechanical connections (connections of the

machine system) and electrical connections (wiring and cabling), and set the necessary parameters properly

before starting normal machine operation .

Before to proceed running the inverter in normal operation check the related function code data again

and

reconfigure it if needed.
