Apply Power To A3 Servo Drive - Delta ASDA-A3 Series User Manual

ASDA-A3

4.5.2 Apply power to A3 servo drive

Please follow the instructions below.
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. Please refer to Section 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. Please refer to Sections
3.1 and 3.4 for the wiring for CN2.
Caution: do not connect the power (R, S, T) to the output terminal (U, V, W) of A3 servo drive,
or you may damage the servo drive.
2. Connect the power circuit for the servo drive:
220V servo drive: connect the power to the servo drive. Please refer to Section 3.1.3 for
power wiring.
3. Turn on the power:
220V servo drive supply: apply power, including to the control circuit (L1c, L2c) and main
circuit (R, S, T).
When the power is on, the display of the servo drive shows:
The default digital inputs (DI6 – DI8) are the signal for reverse inhibit limit (NL), forward inhibit
limit (PL), and emergency stop (EMGS). If DI6 – DI8 is 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 value for a
different function.
If the servo drive status displays P0.002 setting as the motor speed (07), then the screen display
shows:
When the panel displays no text, please check if the control circuit power is undervoltage.
