ASD-B3-0721-L 750W AC Servo Drive Pulse Type 220V | Delta

The Original New Delta ASD-B3-0721-L is a 750 W AC servo drive from the ASDA-B3 series, the pulse-type basic model designed for traditional single-axis positioning and standalone equipment control. Rated 750 W (1 HP) with 5.1 Arms continuous output current and 16.4 Arms instantaneous maximum output current, it operates on 220 V AC single-phase or three-phase input. The drive supports PT Mode (pulse input), PR Mode, RS-485 communication, and analog voltage control, with an industry-leading 3.1 kHz response bandwidth that shortens settling time by 40% compared with previous models. Supporting 24-bit incremental and absolute encoders with up to 6000 RPM motor speed and 350% maximum torque, the ASD-B3-0721-L delivers high-precision motion control for machine tools, packaging machinery, printing equipment, and industrial robots. This model is the pulse-type variant of the ASD-B3-0721 series, offering a cost-effective solution for conventional single-axis applications where EtherCAT multi-axis synchronization is not required.
