The Delta ASDA-B3 series represents a leap in servo drive technology, and the 400W model ASD-B3-0421-L is engineered for demanding industrial automation tasks. Featuring a 24-bit absolute encoder interface, this drive delivers exceptional precision and smoothness at low speeds, making it ideal for applications like packaging, robotics, and CNC machinery. Its compact, IP20-rated design supports both single-phase and three-phase 220VAC inputs, with natural cooling for reliable operation up to 45°C. The drive offers versatile command sources, including external pulse trains and internal PR mode, with a maximum pulse frequency of 4 Mpps. With built-in S-curve and moving filters, torque limit, and feedforward compensation, the ASD-B3-0421-L ensures superior dynamic response and stability. Robust protection functions safeguard against electrical and mechanical faults, while communication options like EtherCAT and CANopen enable seamless integration into modern networked systems.
