Mains and transformer
Input voltage, transformer, frequency and line components must agree with the installed supply design.
A drive-system supply operates as part of a cabinet. Litco reviews the complete supply code together with line components, connected drives, braking hardware and the event that brought the DC bus down.

Configuration-aware intake
Legacy modular drive systems can use one supply to feed several axes through a shared DC link. Supply rating, mains voltage, transformer arrangement, regenerative or bleeder hardware, line chokes and the combined drive load all affect whether a replacement belongs in that cabinet.
Before removing the module, photograph the cabinet layout, supply label, upstream line equipment, DC-bus connections and every alarm or indicator. Do not assume that a damaged-looking supply is the only failed component; the evaluation starts with the whole event and the connected system.
What changes the recommendation
Input voltage, transformer, frequency and line components must agree with the installed supply design.
Connected drive count, current demand and shared-bus arrangement show how the supply is used in the machine.
Bleeder, brake resistor and regenerative hardware affect energy handling during deceleration.
Trips, blown protection, smoke, heat, contamination and faults on neighboring axes help define the inspection.
Before removal or shipment
Follow the machine builder’s lockout and discharge procedures; hazardous stored energy can remain after power is removed.
Show the supply, connected drives, line components, transformer and all DC-bus or braking hardware.
Record the supply, transformer, choke and connected drive codes rather than sending only the failed module number.
Note what the machine was doing, which protections opened and which indicators or messages appeared first.
Only qualified personnel should remove or work around industrial electrical and motion-control equipment. Follow the machine builder’s safety, lockout and stored-energy procedures.

What the first review can establish
Litco reviews the submitted unit and cabinet evidence before defining a repair recommendation.
A replacement is compared by full code, input arrangement, DC-bus role and connected system context.
The intake can identify line, braking or neighboring drive information that should be checked before restart.
