Specification

The Delta ASDA-B3 Series represents a leap forward in servo drive technology, and the ASD-B3-0721-L 750W model is engineered to deliver exceptional torque and speed control for demanding industrial applications. With a 24-bit absolute encoder interface and support for multiple fieldbus protocols, this drive excels in high-speed pick-and-place, packaging, and CNC machinery. Its advanced auto-tuning algorithms and built-in regenerative resistor (for 750W and above) simplify setup while maximizing energy efficiency. The drive’s rugged IP20 enclosure and wide operating temperature range (0°C to 55°C) ensure stable performance in harsh factory environments. Below are the complete technical specifications for the 750W variant, covering electrical, mechanical, and environmental parameters.
