Product Details

The Danaher Motion DSA-068-460-S belongs to the Centurion DSA series, a discontinued high-performance digital servo amplifier designed for driving sinusoidal brushless AC servo motors. This digital servo amplifier delivers precise torque, velocity and position control for automated machinery; it supports multiple command sources including ±10 V analog signal, step and direction, master encoder follow and preset position selection, making this high voltage servo drive highly flexible for retrofitting legacy motion systems. Equipped with built-in shunt dissipation, the DSA-068-460-S accepts a wide-range three-phase high-voltage input and works with incremental encoders, resolvers or Hiperface feedback. Widely used for replacing ageing servo amplifiers on production lines, this Centurion motion controller is stocked as genuine surplus replacement spare part for industrial automation equipment.

Supported Functions

This servo amplifier receives motion commands from host controllers and runs closed-loop servo regulation for brushless motors. It supports electronic gearing for master-slave synchronization, sixty-four configurable preset positions or speed points selected via digital inputs. It provides over-current, over-voltage, under-voltage and over-temperature fault 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 different motion requirements.

Core Functions

The all-digital control architecture guarantees smooth sine-wave commutation and stable low-speed operation. Multiple feedback options allow it to match a broad range of existing servo motors without redesign. The SERCOS and serial ports simplify integration into legacy motion networks, and the robust power stage withstands frequent start-stop cycles in continuous production. It serves as direct drop-in substitution for existing DSA-068-460-S servo amplifiers.
