ASD-B2-1021-B 1kW AC Servo Drive 220V 1/3-Phase | Delta

The Original New Delta ASD-B2-1021-B is a 1 kW AC servo drive from the ASDA-B2 series, designed for general-purpose machine control applications requiring precise positioning and cost-effective motion control. Rated 1 kW (1.3 HP) with 7.3 A output current, it operates on 220 V AC single-phase or three-phase input. The drive supports position, speed, and torque control modes, with a 17-bit encoder (160,000 ppr) for high-precision positioning and smooth low-speed operation. Equipped with RS-232 and RS-485 communication interfaces and compatible with Delta ECMA series servo motors, the ASD-B2-1021-B delivers reliable performance for packaging, textile, material handling, and small CNC applications. The built-in auto-notch filters and friction compensation improve low-speed stability and reduce mechanical resonance.
