ASD-A2-1521-E is a 1.5 kW high-performance AC servo drive from Delta’s A2 series, engineered for medium-power industrial applications requiring high dynamic performance, precision, and reliability. It adopts a 32-bit high-speed DSP controller to optimize the current, speed, and position three closed-loop control structure, achieving fast response, low noise, and high stability. The drive supports 17-bit high-resolution encoder feedback, ensuring excellent positioning accuracy and smooth operation. It features advanced auto-tuning, resonance suppression, friction compensation, and multi-segment command functions, which effectively improve control accuracy and reduce commissioning time. It supports position, speed, and torque control modes, as well as electronic gear and synchronous control for complex motion tasks. The drive provides comprehensive protection functions, including overvoltage, undervoltage, overcurrent, overload, overheating, and stall protection, ensuring safe operation under harsh conditions. It supports multiple communication protocols for easy integration with automation systems. This model is widely used in packaging machinery, woodworking machinery, material handling systems, positioning platforms, and assembly lines, providing high precision, fast response, and reliable motion control.
