ASD-A2-5543-M 5.5kW AC Servo Drive 400V CANopen | Delta

The Original New Delta ASD-A2-5543-M is a 5.5 kW AC servo drive from the high-performance ASDA-A2 series, engineered for demanding motion control applications requiring high precision and powerful output. Rated 5.5 kW (7.5 HP) with 22.37 Arms continuous output current and 48.49 Arms instantaneous maximum output current, it operates on 400 V AC three-phase input. The "M" type model features a built-in CANopen communication interface, enabling high-speed distributed control and seamless integration into motion control networks. 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 with up to 720 points, the ASD-A2-5543-M is the ideal choice for CNC machining centres, flying shears, rotary cutting, and complex multi-axis synchronization tasks.
