Specification

The DELTA ASDA-A3 SERVO DRIVE 100W ASD-A3-0121-L represents the pinnacle of precision servo control, engineered for demanding industrial automation tasks. This drive leverages a 24-bit absolute encoder interface to deliver exceptional contouring accuracy and minimal torque ripple, making it ideal for CNC, robotics, and packaging machinery. With a continuous output current of 0.9 Arms and an instantaneous peak of 3.54 Arms, it provides robust torque control in a compact footprint. The drive supports single-phase or three-phase 220 VAC input, ensuring global compatibility, and features a built-in regenerative resistor for the 100W model, reducing external component requirements. Its advanced SVPWM control and low-pass/P-curve smoothing filters ensure stable operation across a wide speed range. Fully certified to IEC/EN 61800-5-1 and UL 508C, this drive is a reliable choice for OEMs and system integrators seeking high-performance motion control.
