3.2.1 Connecting to Peripheral Devices

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)
CN6 CANopen connector (Optional)
CN6: for ASDA-A2-M only. (Please refer to the
description or section 1.2.2)
CN7 extension DI connector (Optional)
CN7: for ASDA-A2-U only. (Please refer to the
description of section 1.2.2)
Installation Notes:
1. Check if the power and wiring among R, S, T and DC24V, DC0V are correct.
Please refer to Chapter 11 for Specifications. Make sure the input voltage is correct, or it might damage
the servo drive or danger may occur.
2. Check if the output terminal U, V, W of the servo motor is correctly wired. The incorrect wiring may
disable the operation of the motor or cause the malfunction.
3. When applying to the external regenerative resistor, the contact between P
and the external regenerative resistor should connect to terminal P
internal regenerative resistor, the contact between P
P and C should be opened.
4. When an alarm occurs or the system is in emergency stop status, use ALARM or WARN to output and
disconnect the power of magnetic contactor in order to disconnect the power of servo drive.

750W-15kW Three-phase 380-480V±10%
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.
