Product Details

Danaher Motion 401-34400-00, also known as a Giddings & Lewis drive, is an original 10A servo drive and digital servo amplifier built for legacy Giddings & Lewis and Danaher Motion motion control platforms. This compact servo power unit converts incoming power into precisely regulated three-phase AC output to drive matching brushless servo motors, supporting closed-loop torque, speed and position control for high-precision positioning tasks. It accepts analogue and digital command signals from the master controller, processes encoder feedback data in real time, and continuously adjusts power output to maintain stable motor operation. As an obsolete original spare part, this digital servo amplifier is widely used for direct replacement when the existing drive fails on ageing CNC machines and automated production lines. Drop-in installation retains the original machine control program and parameter settings, eliminating the need for major system upgrades and drastically reducing costly production downtime. Equipped with reliable power switching components, built-in current sensing circuitry and comprehensive fault detection logic, the 401-34400-00 delivers consistent and repeatable performance under cyclic dynamic loads and remains a trusted core power spare for legacy motion machinery.
