Specification

The DELTA ASDA-A3 SERVO DRIVE 750W ASD-A3-0721-F is a next-generation servo drive engineered for demanding automation applications requiring high speed, precision, and reliability. This 750W model features a 24-bit absolute encoder, delivering 16,777,216 pulses per revolution for exceptional positioning accuracy. With a continuous output current of 5.1 Arms and an instantaneous maximum of 21.21 Arms, it handles rapid acceleration and deceleration tasks effortlessly. The drive supports multiple control modes including external pulse train (PT) and internal parameter (PR) modes, and offers a maximum input pulse frequency of 4 Mpps in pulse + direction or CW/CCW configurations. Built for versatility, it integrates RS-485, CANopen, and USB communication interfaces, and operates on single-phase or three-phase 220 VAC power (200–230 VAC, -15% to 10%). The fan-cooled design ensures stable performance up to 55°C, while the IP20 enclosure protects against dust and debris. Ideal for CNC machines, packaging equipment, robotics, and textile machinery, the ASD-A3-0721-F is a reliable choice for modern industrial automation systems.
