ASD-A2-1021-L 1kW AC Servo Drive 220V 1/3-Phase 7.3A | Delta

The Original New Delta ASD-A2-1021-L is a 1 kW AC servo drive from the ASDA-A2 series, Delta's high-performance motion control platform designed for demanding industrial automation applications. Rated at 7.3 A continuous output current with a 220 V AC single/three-phase input, it delivers precise position, speed, and torque control for machine tools, packaging machinery, and electronics manufacturing equipment. The drive features a 20-bit incremental encoder resolution (1,280,000 pulses/revolution) and supports pulse input, analog voltage control, PR mode, and full-closed loop control. Built-in RS-232/RS-485 communication and CANopen enable integration into networked motion control systems. The "-L" suffix indicates a model without built-in electronic cam (E-CAM) function and without additional discrete input ports, making it a cost-effective solution for standard motion control applications.
