YASKAWA SRDA-CUA662AADX200 HW0273067-5 Motoman DX Cable

Product Overview

YASKAWA SRDA-CUA662AADX200 HW0273067-5 Motoman DX Servo Power Cable — System Stability & Industrial Spare Value

The YASKAWA SRDA-CUA662AADX200 (HW0273067-5) is a genuine OEM servo power cable engineered for the Motoman DX100 and DX200 robot controller series. Designed to deliver stable, high-current power transmission between the servo amplifier and the robot arm drive unit, this cable is a critical link in maintaining continuous, fault-free robotic operation across automotive assembly, arc welding, material handling, and precision manufacturing environments. When a servo power cable degrades — through insulation fatigue, connector wear, or repeated flex cycles — the consequences range from intermittent servo alarms to full production stoppage. Stocking a verified replacement of the SRDA-CUA662AADX200 is one of the most cost-effective decisions a maintenance team can make.

Preventive Maintenance Strategy

A servo power cable failure rarely occurs in isolation. In a Motoman DX100 or DX200 robot cell, the servo power cable works in concert with a tightly integrated set of components — and a scheduled maintenance inspection should address all of them together to avoid repeat downtime.

When replacing the SRDA-CUA662AADX200, maintenance engineers should simultaneously inspect the SRDA-SDA661A servo amplifier module, which is the upstream power source for this cable. Amplifier output connectors and terminal blocks can develop micro-arcing over time, especially in high-cycle welding or press-tending applications. Alongside the amplifier, the JZRCR-YPU01B power supply unit for the DX controller should be checked for capacitor aging and output voltage stability — a marginal power supply will stress cables and drive units even after a fresh cable installation.

The SRDA-EAXA01A servo control board and its associated SRDA-COA01A I/O interface board are also worth inspecting during the same maintenance window. These boards govern servo command signals and feedback loops; a degraded I/O board can cause erratic axis behavior that is often misdiagnosed as a cable fault. Similarly, the JARCR-XFB01B brake control relay module should be tested — brake relay contacts wear over time and can cause axis drop alarms that mimic servo cable issues.

For the robot arm side, inspect the HW0470360-A encoder cable and the HW0371464-A signal harness at the same time as the power cable. Encoder cables and power cables share the same cable duct and experience identical flex fatigue; replacing one without inspecting the other is a common source of repeat service calls. The JZNC-YRK01-1E robot controller backplane and its internal bus connectors should also be reseated and visually inspected for corrosion or heat discoloration during any major cable replacement job.

Finally, review the condition of the DX200 teach pendant cable (HW0470148-A) and the JZRCR-YEW01-1 Ethernet communication module if the cell is networked. Communication faults during servo recovery after a cable replacement are often traced back to a pre-existing pendant cable or network module issue that was masked by the original alarm.

Stocking all of these components as a coordinated spare kit — rather than reacting to each failure individually — dramatically reduces mean time to repair (MTTR) and protects production schedules in high-OEE environments.

Strategic Replacement Solutions

The Motoman DX100 and DX200 controller platforms have been deployed globally since the mid-2000s and remain in active service across thousands of manufacturing facilities. YASKAWA has progressively transitioned its newer installations to the YRC1000 and YRC1000micro platforms, which means that genuine DX-series spare parts — including the SRDA-CUA662AADX200 — are becoming increasingly difficult to source through standard distribution channels.

TOPNLMS specializes in exactly this scenario: sourcing, testing, and supplying verified OEM spare parts for legacy robot controller systems that are no longer in active production. Every unit of the SRDA-CUA662AADX200 we supply is inspected for connector integrity, insulation continuity, and conductor resistance before dispatch. This pre-shipment testing protocol ensures that the replacement cable performs identically to the original factory-installed unit — eliminating the risk of installing a defective spare during a critical maintenance window.

For facilities managing a fleet of DX100 or DX200 robots, we recommend establishing a minimum stock level of at least one SRDA-CUA662AADX200 per robot cell. The cable’s flex life is finite, and in high-cycle applications (welding, palletizing, press tending), proactive replacement at scheduled intervals — rather than waiting for failure — is the industry-standard approach to maximizing robot uptime. Our team can assist with multi-unit procurement planning, volume pricing, and lead-time commitments to support your annual maintenance budget.

For facilities considering a phased migration from DX100/DX200 to YRC1000, we can also supply the transition-period spares inventory needed to keep legacy cells running reliably while new systems are commissioned — protecting capital investment and avoiding premature decommissioning of productive robot assets.

Support FAQ

Q1: What warranty does the SRDA-CUA662AADX200 carry?
All units supplied by TOPNLMS carry a 12-month quality warranty from the date of shipment. If the cable exhibits any manufacturing defect or fails under normal operating conditions within the warranty period, we will arrange a replacement or full refund. Our warranty covers both new OEM stock and tested surplus units.

Q2: How do I verify compatibility with my specific DX100 or DX200 system?
The SRDA-CUA662AADX200 is a direct OEM replacement for Motoman DX100 and DX200 controllers. To confirm compatibility, cross-reference the part number on your existing cable label or in your robot’s maintenance manual under the servo power cable assembly section. The cross-reference number HW0273067-5 can also be used to verify against YASKAWA’s official parts documentation. If you need assistance confirming fitment for your specific robot model or axis configuration, contact our technical team at [email protected].

Q3: What pre-shipment testing is performed on each cable?
Each SRDA-CUA662AADX200 unit undergoes a multi-point inspection before dispatch: connector pin continuity check, insulation resistance test, visual inspection of the cable jacket and strain relief, and connector locking mechanism verification. A test report is available upon request for quality-critical procurement processes.

Q4: Can I order multiple units for a planned maintenance stock program?
Yes. TOPNLMS supports both single-unit emergency orders and multi-unit planned stock procurement. For orders of 3 or more units, please contact us directly for volume pricing and lead-time confirmation. We maintain stock of DX-series servo cables and can provide delivery commitments aligned with your annual maintenance planning cycle.
