Test Operation and Panel Display

4.5.2 Apply power to A3 servo drive

Follow the steps.

1. Make sure the wiring between the motor and servo drive is correct:

(1) U, V, W, and FG have to connect to the red, white, black, and green wires respectively.

If the wiring is incorrect, the motor cannot work properly. The motor ground cable FG

must connect to the drive’s ground terminal. Refer to Sections 3.1 - 3.2 for wiring.

(2) The encoder cable for the motor is correctly connected to CN2: if you only want to use

the JOG function, connecting CN1 and CN3 is not necessary. Refer to Section 3.5 for

the wiring for CN2.

Caution: do not connect the power (R, S, T) to the output terminal (U, V, W) of the A3 servo

drive, or it may damage the servo drive.

2. Connect the power circuit for the servo drive:

Connect the power to the servo drive. Refer to Sections 3.1.3 and 3.2.3 for power wiring.

3. Turn on the power:

Power supply: apply power to the control circuit (L1C, L2C) and main circuit (R, S, T).

◼ When the power is on, the display of the servo drive shows:

4

The default digital inputs (DI6 - DI8) are the signals of negative limit (NL), positive limit (PL), and

emergency stop (EMGS). If DI6 - DI8 are not used, you must change the values of P2.015 -

P2.017, which you can set to 0 (disable the DI function) or some other values for different

functions.

◼ When the servo drive status displays the P0.002 setting as the motor speed (07), then the

screen display shows:

When the panel displays no text, check if the control circuit power is undervoltage.
