RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Detailed electrical parameters (rated current, bus voltage, encoder interface spec) vary by axis configuration. Confirmed specifications are provided upon request with unit serial number verification. No parameters are stated here that cannot be independently verified.

Solving the Discontinued Hardware Crisis

The DX100 controller was Yaskawa's dominant industrial robot platform for over a decade, deployed across automotive body welding, semiconductor handling, food packaging, and general assembly lines worldwide. The YRC1000 succeeded it but shares a significant portion of the servo drive architecture during the transition period — meaning SGDR-series servopacks remain embedded in active production environments that have no near-term retirement plan.

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

Facilities that have invested in Yaskawa robot infrastructure over 10–15 years have accumulated institutional knowledge, calibrated tooling, and validated processes built around the DX100/YRC1000 platform. Replacing a $400 servo drive to preserve that investment is not a compromise — it is sound asset management. The alternative, a six-figure controller replacement triggered by a single failed component, is a cost that no maintenance budget should absorb unnecessarily.

Condition & Reliability Assurance

Discontinued servo drives sourced from the secondary market carry inherent risk if not properly evaluated. DriveKNMS applies a structured 5-step inspection protocol to every SGDR-series unit before it is offered for sale:

1. Electrolytic capacitor assessment. Capacitor aging is the primary failure mode in stored servo drives. Each unit is inspected for capacitor bulging, electrolyte leakage, and ESR degradation. Units with compromised capacitors are either recapped with specification-matched components or rejected.
2. Firmware version verification. The firmware version is read and recorded. Units are matched to compatible controller firmware ranges. Mismatched firmware is flagged before dispatch review, not after installation.
3. Connector and pin corrosion inspection. All signal and power connectors are inspected under magnification for oxidation, pin deformation, and contamination. Corroded contacts are cleaned or the connector assembly is replaced.
4. Functional power-on test. Where test fixtures are available for the specific drive model, units are powered and basic operational parameters are verified prior to packaging.
5. Packaging for long-term storage. Units are packaged in anti-static bags with desiccant and sealed for protection during transit and storage.

Key Features for System Maintenance

• Drop-in replacement. The SGDR-SDB950A01DY500 installs directly into the DX100 or YRC1000 controller chassis without mechanical modification.
• No reprogramming required. Robot teach data, job files, and system parameters remain intact. Replacement does not trigger a re-teach requirement under normal conditions.
• No engineering re-qualification. A like-for-like servo drive replacement does not constitute a system modification requiring formal re-validation in most industrial environments, avoiding the cost and delay of an engineering change order.
• Immediate production restoration. A verified replacement unit allows production to resume within the time required for physical swap and system restart — measured in hours, not weeks.

How do I confirm the unit is genuine Yaskawa?
All units supplied by DriveKNMS are inspected for manufacturer markings, label integrity, and internal construction consistent with genuine Yaskawa production. We do not knowingly supply counterfeit components. Customers may request inspection photos prior to shipment.
