Product Details

The Danaher Motion 401-34317-30, also known as Giddings & Lewis AS130 BSA brushless servo amplifier, is a legacy rack‑mounted servo drive designed for Giddings & Lewis CNC machine tool systems. This AS130 BSA amplifier converts command signals from the CNC controller into precise power output to drive brushless servo motors for feed axes and spindle auxiliary motion. As a reliable CNC servo amplifier, it adopts robust power modules, built‑in signal conditioning and comprehensive fault detection circuitry to withstand voltage fluctuations, electromagnetic interference and continuous heavy‑duty cycles inside CNC control cabinets. This Giddings & Lewis servo drive is widely used for replacement and refurbishment of ageing machining centers and turning centers, restoring accurate axis positioning and smooth motion performance; it is stocked as genuine replacement spare part for industrial CNC equipment.

Supported Functions

This servo amplifier receives motion commands from the host CNC controller and performs closed‑loop torque, speed and position regulation for matched brushless servo motors. It processes resolver and encoder feedback to minimize axis tracking error and supports rapid traverse, feed and jog motion modes for machine tool operation. It continuously monitors internal temperature, output current and power supply status, and outputs fault codes for diagnosis upon abnormal conditions. It supports synchronized multi‑axis movement to execute complex NC machining programs.

Core Functions

The standard rack form factor fits directly into the original Giddings & Lewis control rack without modification. Its native signal interface guarantees seamless communication with legacy G&L CNC systems and FSM servo motors. All pin definitions and bus protocols follow factory original specifications, so no major wiring redesign is needed during swap, and it serves as direct drop‑in substitution for existing 401-34317-30 AS130 BSA servo amplifiers.
