ASD-A2-0721-E 750W AC Servo Drive EtherCAT 220V 1/3-Phase | Delta

The Original New Delta ASD-A2-0721-E is a 750 W AC servo drive from the high-performance ASDA-A2 series, featuring an integrated EtherCAT communication interface for high-speed, synchronized multi-axis motion control. Rated 750 W (1 HP) with 5.1 A continuous output current, it operates on 220 V AC single-phase or three-phase input. The "E" type model integrates EtherCAT (CoE) protocol with a minimum cycle time of 250 µs, enabling the drive to serve as a high-speed slave node in complex synchronized systems. Supporting position, speed, and torque control modes, 20-bit encoder feedback (1,280,000 pulses/rev), full-closed loop control, and electronic cam (E-CAM) profiles, the ASD-A2-0721-E is designed for high-speed packaging, automated assembly, and semiconductor processing equipment.
