Technical Specifications

Solving the Discontinued Hardware Crisis

For a facility running multiple axes on multiple machines, the arithmetic is straightforward. A stockpile of verified original L720-012EL8 units extends the productive life of that asset base by years — often a decade or more — at a fraction of the retrofit cost. This is not a temporary fix. It is a deliberate asset protection strategy used by maintenance organizations that manage capital equipment with long depreciation cycles.

DriveKNMS sources L720-012EL8 units through established industrial surplus and decommissioning channels. Each unit is physically inspected before listing. We do not list units we cannot verify.

Condition & Reliability Assurance

Obsolete servo motors sourced from the secondary market carry real risks. Our 5-step QA process addresses the failure modes that matter for a motor of this age:

• Step 1 – Visual and mechanical inspection: Housing integrity, shaft runout check, connector and pin condition. Corrosion on motor terminals is a primary failure indicator and is assessed under magnification.
• Step 2 – Electrolytic capacitor assessment: Where accessible on associated drive components, capacitor aging is evaluated. Bulging, leakage, or elevated ESR readings result in rejection or documented disclosure.
• Step 3 – Winding resistance and insulation check: Armature and field winding resistance is measured. Insulation resistance to frame is tested to confirm no breakdown has occurred.
• Step 4 – Encoder / feedback device verification: Feedback signals are checked where test equipment permits. Units with unverifiable encoder condition are disclosed as such.
• Step 5 – Firmware and label verification: Part number markings, date codes, and any firmware revision labels are cross-referenced against known L720-012EL8 production records to confirm authenticity.

Units that do not pass all verifiable steps are either rejected from inventory or listed with explicit condition disclosure. We do not represent a failed unit as serviceable.

Key Features for System Maintenance

How do I know the unit is genuine and not a counterfeit or mismarked part?
All units are inspected against known L720-012EL8 production markings and physical characteristics. We do not source from channels known to produce counterfeit industrial components. If you have specific authentication requirements, contact us before purchase and we will provide available documentation.

Should I buy more than one unit?
For any machine where this motor is a single point of failure on a critical production axis, holding at least one spare unit is standard practice. If you operate multiple machines with L-Series motors, a small stockpile is a defensible capital allocation. The alternative — sourcing under emergency conditions when a machine is down — typically costs more and takes longer.

Can you source other Sanyo Denki L-Series variants?
Yes. Contact us with your specific part number. We maintain relationships with surplus suppliers across multiple regions and can often locate variants not currently listed.
