Technical Specifications

Note: Electrical parameters such as rated current, input voltage range, and encoder interface specifications are verified against physical unit markings and documentation at time of inspection. Specifications are not published here to prevent misapplication — contact us for a datasheet matched to your serial number range.

Solving the Discontinued Hardware Crisis

The Lexium servo drive series was a cornerstone of Schneider Electric's motion control portfolio for over a decade. Its integration into Modicon PLC environments — particularly systems running Unity Pro or PL7 software — created a tightly coupled architecture that cannot be casually swapped for a current-generation drive without significant re-engineering effort.

Factory managers facing the retirement of Lexium-based lines confront a straightforward but painful calculation: the cost of a controlled, phased maintenance strategy using verified spare parts versus the cost of an unplanned failure that forces an emergency system overhaul. The latter rarely costs less than several hundred thousand dollars when lost production, engineering labor, and expedited procurement are factored in.

Condition & Reliability Assurance

Obsolete parts sourced from secondary markets carry inherent risk. DriveKNMS applies a 5-step inspection protocol before any unit is offered for sale:

• Step 1 – Visual and Mechanical Inspection: Enclosure integrity, connector pin condition, and corrosion assessment on all exposed contacts and PCB surfaces.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in stored servo drives. Each unit is evaluated for capacitor bulging, leakage, and ESR deviation. Units with compromised capacitors are either reconditioned by qualified technicians or removed from inventory.
• Step 3 – Firmware Version Verification: Where accessible, firmware revision is documented and cross-referenced against known compatibility requirements for the target system.
• Step 4 – Functional Power-On Test: Units are powered and tested for basic initialization and fault-free startup where test bench infrastructure supports the specific drive model.
• Step 5 – Packaging and ESD Protection: Units are repackaged in anti-static materials with desiccant to prevent moisture ingress during storage and transit.
