Specification

The DELTA ASDA-B2 Servo Drive 1.5kW, specifically the ASD-B2-1521-B, represents a robust solution for industrial automation systems requiring precise motion control. This drive integrates advanced SVPWM control with a 17-bit absolute encoder feedback, delivering exceptional positioning accuracy and speed stability. Designed for demanding applications such as packaging, labeling, and CNC machinery, the ASD-B2-1521-B offers flexible command sources (pulse train, analog signal, or internal parameters) and supports both position and speed/torque loops. Its built-in dynamic brake for the 1.5kW variant enhances safety during emergency stops, while the fan cooling system ensures consistent performance under continuous load. With a maximum input pulse frequency of 4 Mbps in high-speed mode and an electronic gear ratio range of 1/50 to 25600, this drive is optimized for high-throughput environments.
