Product Details

The Danaher Motion DSA-046-460-S belongs to the Centurion DSA series, a discontinued high-performance digital servo amplifier designed to drive sinusoidal brushless AC servo motors. This digital servo amplifier delivers precise torque, velocity and closed-loop position control for automated industrial machinery. It supports multiple command sources including ±10 V analog signal, step and direction, master encoder follow and preset position selection, making this Centurion servo drive ideal for retrofitting legacy motion equipment. Equipped with integrated shunt dissipation, the DSA-046-460-S accepts three-phase high-voltage input and works with incremental encoders, resolvers and Hiperface feedback devices. It is widely adopted to replace ageing servo amplifiers on production lines and stocked as genuine spare part for industrial automation systems.

Supported Functions

This servo amplifier receives motion commands from host controllers and carries out closed-loop regulation for brushless servo motors. It supports electronic gearing for master-slave synchronization and a set of preset speed or position points selectable via digital inputs. It provides full fault protection including over-current, over-voltage, under-voltage and over-temperature protection, and transmits diagnostic status over serial bus for remote monitoring and troubleshooting. It can operate as velocity drive, positioning drive or encoder follower to satisfy diverse motion control demands.

Core Functions

The all-digital control architecture realizes smooth sine-wave commutation and stable low-speed running. Multiple feedback options enable it to pair with a wide range of existing servo motors without redesign. SERCOS and serial communication ports simplify integration into legacy motion networks, and its sturdy power stage withstands frequent start-stop cycles under continuous production. It serves as direct drop‑in substitution for existing DSA-046-460-S servo amplifiers.
