Description
Yaskawa JANCD-XTU01B | Motoman XRC Power-On Board
Product Introduction
A startup-board fault in a legacy robot controller can prevent the entire system from reaching its normal operating state. Replacing the board requires more than matching its appearance: the correct controller platform, board revision, rack connection, and startup-circuit configuration must be verified.
The Yaskawa JANCD-XTU01B is identified in Motoman XRC controller parts documentation as a Power On Board. This distinguishes it from the XRC system CPU board, general I/O boards, and servo-control hardware. Secondary supplier material also associates the board with power-up sequencing and controller startup functions.
For maintenance teams sourcing this discontinued component, the priority is exact configuration matching. Verify the full JANCD-XTU01B designation, revision, controller model, and physical board markings before purchase. Do not assume that a similar JANCD board—or a board described generically as an I/O interface—is a suitable substitute.

Global Sourcing & Live-Test SOP
For a legacy XRC power-on board, the procurement process should establish identity, physical condition, and controller-level functionality.
1. Inbound Verification
- Photograph the complete nameplate and all board markings.
- Confirm JANCD-XTU01B, including the suffix.
- Record serial number, revision, and any additional OEM identifiers.
- Photograph both sides of the PCB, connectors, and mounting features.
- Inspect for corrosion, cracked components, heat discoloration, damaged pins, or evidence of repair.
- Compare the board against the customer’s original assembly.
- Verify any associated part number against the physical label rather than relying solely on a supplier listing.
- Retain available traceability and service records.
2. Pre-Power Inspection
- Identify the exact Motoman XRC controller model.
- Confirm board position and electrical requirements from the applicable OEM documentation.
- Inspect rack contacts and connectors for contamination, oxidation, or mechanical damage.
- Check for visible component damage or unauthorized modifications.
- Confirm that the board revision and installed configuration match the intended application.
- Do not apply power based on unverified online voltage claims.
- Avoid probing undocumented pins or applying insulation-test voltages through electronic circuitry.
3. Controlled Functional Test
A meaningful test requires a compatible XRC controller or an approved test setup.
- Verify the board’s identity and controller compatibility before installation.
- Follow the applicable XRC power-down and installation procedure.
- Confirm the controller’s backup and recovery status before replacing the original board.
- Check startup behavior and available controller diagnostics.
- Verify that the XRC system recognizes the board and reaches the expected startup state.
- Monitor for startup faults, abnormal behavior, or unexpected resets.
- Record the controller model, board revision, test conditions, and observed results.
A board that appears undamaged or passes a basic continuity check should not automatically be classified as fully functional.
4. Extended Run and Diagnostic Record
Where a compatible test system is available, perform an extended controller startup and operation test.
Monitor:
- Controller startup consistency
- Diagnostic and alarm status
- Unexpected resets or power-up failures
- Abnormal heating
- Intermittent operation
- Related controller faults
Record the test duration, XRC configuration, board revision, and results. Do not claim a full robot-motion test or 24-hour heat run unless it was actually completed and documented.
5. Final Preparation and Shipment
- Photograph the actual board being shipped.
- Record the complete model number, serial number, and revision.
- Protect edge contacts and connectors from impact.
- Use ESD-safe packaging.
- Include available inspection and test documentation.
- State condition and warranty terms clearly.
- Do not claim OEM certification, factory testing, or retained controller data without evidence.
Field Engineer’s Pitfall Guide
❗ Do not confuse the Power On Board with the XRC CPU board
The is identified as the XRC Power On Board, while the JANCD-XCP01-1 is listed separately as the System Control Board. These are distinct controller components; verify the failed board’s exact designation before ordering.
❗ Do not use unverified voltage or I/O specifications
Some secondary listings assign generic electrical and I/O figures to the without a clear model-specific OEM reference. Confirm the board’s actual electrical requirements and function from the applicable XRC documentation before installation.
❗ A startup-board replacement may affect controller recovery
The is part of the controller’s power-on/startup architecture. Before replacing it, document the existing fault condition and follow the XRC maintenance procedure. Do not assume that replacing the board alone will resolve faults originating in the power supply, safety circuit, rack, or another controller component.
Intent-Driven FAQ
What is the Yaskawa ?
The is identified in Motoman XRC parts documentation as a Power On Board used in the robot controller.
Is the the main XRC CPU board?
No. The XRC parts list identifies the JANCD-XCP01-1 separately as the System Control Board and the as the Power On Board.
What controller uses the ?
Secondary documentation identifies it for the Motoman XRC controller family. Confirm the exact XRC model and board revision before ordering.
What voltage does the require?
A reliable model-specific voltage rating has not been established here. Verify the electrical requirements from the correct XRC documentation and the physical board identification before applying power.
Can the replace the JANCD-XTU01?
Do not assume interchangeability based on the similar model numbers. Confirm revision differences, controller compatibility, connector arrangement, and OEM replacement guidance.
Is the discontinued?
Secondary industrial-parts references list the as discontinued by the manufacturer. Availability and condition therefore depend on remaining inventory and qualified repair or surplus channels.
What should I request before buying a used ?
Request actual-unit photographs, a clear nameplate image, serial and revision details, confirmation of the target XRC controller, condition disclosure, documented test scope, and written warranty terms.
Bottom Line for Buyers
The is a legacy Motoman XRC Power On Board—not a generic I/O module or main CPU board. Its replacement suitability depends on the exact XRC controller configuration, board revision, and startup-circuit compatibility.
For procurement, match the complete part number, verify the physical board and revision, and request a documented controller-level test. If the electrical details or compatibility cannot be established, classify the unit as an unverified legacy spare, not a guaranteed drop-in replacement.
