Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Solving the Discontinued Hardware Crisis

The 1326AB series was designed for precision motion control in demanding industrial environments — packaging lines, CNC machining centers, material handling systems, and automated assembly. These systems were engineered for 20–30 year service lives, and many remain mechanically sound. The problem is not the machine; it is the availability of the servo motor that drives it.

The factories that avoid this crisis share one practice: they maintain a strategic inventory of critical spare parts for every discontinued component in their automation architecture. For a 1326AB-B515E-21, the cost of one spare unit is a fraction of one day of lost production. The math is not complicated. The risk of not acting is.

How to extend the service life of your legacy motion control system by 5–10 years:

Condition & Reliability Assurance

Discontinued servo motors sourced from the secondary market carry inherent risk. DriveKNMS applies a structured 5-step quality assurance process to every 1326AB-B515E-21 unit before it leaves our facility.

1. Electrolytic Capacitor Assessment: Capacitor aging is the primary failure mode in stored servo motors. Each unit undergoes inspection for capacitor condition, with particular attention to electrolyte leakage, case deformation, and ESR deviation.
2. Firmware and Nameplate Verification: The unit's nameplate data is cross-referenced against the part number to confirm the correct revision and configuration. No substitutions are accepted.
3. Pin and Connector Corrosion Inspection: All electrical connectors, encoder pins, and power terminals are inspected under magnification for oxidation, corrosion, and mechanical damage. Affected contacts are cleaned or flagged for disclosure.
4. Insulation Resistance Test: Winding insulation is tested to confirm integrity. Units that fail this test are quarantined and not offered for sale.
5. Functional Run Test (where applicable): Units are tested under controlled conditions where test equipment is available for the specific motor configuration.

Units are classified as New (factory-sealed, original packaging), Refurbished (tested, reconditioned to functional specification), or Used-Tested (operational, sold as-is with test documentation). Classification is disclosed at point of sale.

Key Features for System Maintenance

• Drop-in replacement: The 1326AB-B515E-21 is a direct mechanical and electrical replacement for the original unit. No modifications to the drive system, mounting, or wiring are required.
• No reprogramming required: The replacement motor retains the same encoder interface and electrical characteristics as the original. Existing drive parameters remain valid.
• Avoids engineering reconstruction costs: A verified spare eliminates the need for system redesign, new drive procurement, cable rerouting, and the associated engineering hours that accompany a forced platform migration.
• Preserves validated process parameters: In regulated industries — pharmaceutical, food processing, aerospace — a like-for-like replacement avoids the revalidation burden that a system change would trigger.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.
