Product Details

The Danaher Motion DSM-120 belongs to the Centurion DSM series, a compact discontinued digital servo amplifier for brushless AC servo motors. This Centurion servo amplifier delivers precise torque, velocity and position closed-loop control for automated machinery. It supports ±10V analog command, step and direction, master encoder follow and preset positioning, making this compact servo drive suitable for retrofitting legacy motion systems. It features built-in shunt power dissipation and works with incremental encoders, resolvers and Hiperface feedback. This digital motion drive is widely used as replacement spare for old production equipment and stocked as genuine spare part for industrial automation.

Supported Functions

This servo amplifier receives motion commands from the host controller and performs closed-loop regulation for brushless servo motors. It supports master-slave electronic gearing and multiple preset position or speed points selected by digital inputs. It provides over-current, over-voltage, under-voltage and over-temperature fault protection, and supports serial communication for parameter tuning and fault diagnosis. It can run as velocity drive, positioning drive or encoder follower for different motion tasks.

Core Functions

The compact form factor saves cabinet space for machine retrofit. The all-digital control achieves smooth sine-wave commutation and stable low-speed operation. Multiple feedback selections allow matching many existing servo motors without redesign. The DSMPro software enables easy parameter setup and online waveform monitoring, and it serves as direct drop‑in substitution for existing DSM-120 servo amplifiers.
