Specification

The Delta ASDA-B2L-0721-B is a 750W servo drive from the renowned ASDA-B2 series, engineered for demanding motion control tasks in packaging, textile, and CNC machinery. This drive combines advanced SVPWM control with a 17-bit encoder to deliver smooth torque and speed regulation. Its versatile command inputs—external pulse train, analog signals, or internal parameters—allow seamless integration into diverse systems. With a maximum responsiveness of 550Hz and multiple smoothing filters (low-pass and S-curve), the ASD-B2L-0721-B ensures stable operation even under dynamic loads. The built-in dynamic brake on 750W models provides reliable stopping, while the electronic gear ratio (1/50 < N/M < 25600) simplifies axis scaling. This unit is ideal for applications requiring high-speed precision, such as pick-and-place, cutting, and indexing.
