Product Overview
The Delta ASD-A2-0721-L is a
750 W single-axis AC servo drive
from Delta's ASDA-A2 Series.
Designed for 220 V class, single-phase or three-phase
200-230 VAC power systems, the drive provides
RS-485 Modbus communication through CN3
and supports external pulse train commands for position control.
The ASDA-A2-L configuration also offers
full closed-loop feedback through CN5,
analog voltage control, and internal PR positioning.
Full closed-loop control in PR Mode is not supported
on this A2-L variant. CANopen, DMCNET, EtherCAT,
E-CAM and hardware STO are not provided on this model.
