ASD-B2-1521-B 1.5kW AC Servo Drive 220V 1/3 Phase | Delta

The Original New Delta ASD-B2-1521-B is a 1.5 kW AC servo drive from the ASDA-B2 series, designed for high-precision positioning control in general-purpose machine tool and industrial automation applications. Rated 1.5 kW (2 HP) with 8.3 Arms continuous output current and 24.90 Arms instant maximum 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 maximum pulse input frequency of 4 Mpps for high-precision positioning. Equipped with RS-232 and RS-485 communication interfaces, the ASD-B2-1521-B enables flexible integration into automation systems. It is compatible with Delta ECMA series servo motors, particularly the ECMA-E21315RS for 1.5 kW applications.
