3.14 Differences between A2-XN and A2 Series Servo Drives

The hardware connection structure of A2-XN series (X represents L, M, F, and N) is very similar to
that of the A2 series. The following section illustrates their differences in detail.

3.14.1 Connecting to Peripheral Devices (A2-EN model as an example)

Electromagnetic contractor (MC)
When an alarm occurs, it outputs ALARM
signal and disconnect the power of the servo
drive.
Regenerative resistor (Optional)
The returned regenerative power
generated when braking may result in
damage. Thus, external resistor is
recommended. Connect the external
resistor to P and C, and ensure an
open circuit between P and D. When
applying internal resistor, ensure the
circuit is close between P and D, and
the circuit is open between P and C.
CN5 connector (Optional)
For full-closed loop or linear scale connection.
CN5: for ASDA-A2-L, -M, -U. (Please refer to the
description of section 1.2.2)
CN7 extension DI connector (Optional)
(Please refer to the description of section 1.2.2
for supporting series.)
Motor power output (U, V, W)
Servo motor
Power
100W-1.5kW Single/Three-phase 200-230V
2kW-15kW Three-phase 200-230V
No Fuse Breaker (NFB)
Installing a NFB can prevent excessive current from arising due to
short-circuit or flow when power on and off, so as to avoid the
damage on the servo drive.
It can connect to Delta PLC controller or other
brands of NC controllers.

varies from models of
different watt. Please
