Yaskawa JARCR-XSC01 Servo Control Board

Description

Product Introduction & Engineering Value

The Yaskawa JARCR-XSC01 belongs to the older Motoman robot-controller generation used with XRC-series equipment. It is a controller-level PCB, not a general-purpose PLC module. Its role makes exact part-number and revision matching particularly important when maintaining a legacy robot cell.

There is also evidence of multiple board descriptions and revisions for this part number. One industrial listing identifies a Rev. B00 XRC 2001 board, while another identifies a Rev. C0 version associated with HE0200032. That is a strong reason to compare the physical board revision, identification label, and controller configuration before substitution.

Technical Specifications

A secondary industrial database explicitly describes JARCR-XSC01 as a “CONTROL BOARD, FRONT I/O, PANEL MOUNT, ON-BOARD BATTERY.” Another source identifies the same model as a Motoman Servo Control Board Rev. B00 for XRC 2001. These differing descriptions reinforce the need to use the actual board label and revision when qualifying a replacement.

Related Identification

The part has also been cross-referenced with 46S03152-0010 and 146966-1 in industrial spare-parts databases. A separate Motoman spare-parts reference identifies JARCR-XSC01 / 146966-1 as a board used with an explosion-proof PX/XRC2001 programming-pendant interface. These references should be treated as cross-reference information, not as proof that every JARCR-XSC01 configuration is interchangeable.

Field Application & the “Trench” Experience

A 20-year-old Motoman robot can still perform its production task perfectly well while the controller electronics become the weak link. An intermittent controller-board fault can present as unexplained initialization errors, I/O problems, communication failures, or a robot that stops during startup.

In one plausible maintenance scenario, a legacy XRC 2001 robot cell is scheduled for a short maintenance window. The controller repeatedly fails initialization. After isolating the power supply, external I/O, and cabling, the maintenance team traces the fault to the controller PCB. The spare must match not only , but also the installed board revision and associated configuration.

Typical applications include:

1. Legacy Motoman welding cells
2. Automotive body and fixture handling robots
3. Material-transfer robots using XRC 2001 controllers
4. Explosion-proof Motoman robot installations
5. Legacy robot cells where controller replacement is impractical

The XRC 2001 association and explosion-proof PX/XRC2001 references are supported by industrial spare-parts records.

Transparency SOP: QA & Testing

For New Surplus or Refurbished JARCR-XSC01 inventory, a simple continuity check is not sufficient.

Board identification

• Verify .
• Record the PCB revision.
• Check related identification such as HE0200032, where present.
• Photograph all labels before installation.

Physical inspection

• Examine connectors and edge contacts.
• Inspect the PCB for oxidation, contamination, cracked solder joints, or component damage.
• Check mounting hardware and board supports.
• Inspect the onboard battery and battery holder.

Electrical testing

• Verify power-rail behavior using an appropriate controller test fixture.
• Check for abnormal current draw.
• Confirm that the board initializes correctly.

Controller-level testing

1. Install the board in a compatible XRC controller.
2. Verify controller initialization.
3. Check communication and I/O functions.
4. Confirm servo/control diagnostics.
5. Run a controlled robot test before returning the cell to production.

For refurbished stock, testing should ideally be performed in an actual compatible controller rather than only on a bench.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Ignoring the board revision.

JARCR-XSC01 references include at least Rev. B00 and Rev. C0 examples. Do not assume the revision is irrelevant simply because the base part number is identical.

⚠️ Trap #2 — Confusing the board’s role.

Online listings do not describe this part consistently. Some call it a servo control board, while others identify it as a front-I/O/panel-mount control board. For procurement, use the physical board number and controller application rather than relying on a generic category description.

⚠️ Trap #3 — Forgetting the onboard battery.

Parts references specifically report an on-board battery for this board. On an old robot controller, battery condition should be checked during maintenance rather than waiting for a controller-memory problem to appear.

PRO TIP: When sourcing a replacement, provide JARCR-XSC01 + PCB revision + XRC controller model + board photograph. If the board also carries HE0200032, 46S03152-0010, or another secondary number, provide that information as well.

Dynamic FAQ

What is Yaskawa JARCR-XSC01?

It is a legacy Yaskawa Motoman controller PCB associated with the XRC 2001 robot-controller platform. Industrial parts references describe it as a control/servo interface board.

Which controller uses JARCR-XSC01?

The strongest product-specific references associate it with Motoman XRC 2001 equipment. It is also referenced in connection with PX/XRC2001 applications.

Is JARCR-XSC01 discontinued?

Yes. Industrial parts databases list the JARCR-XSC01 as discontinued by the manufacturer.

Are all JARCR-XSC01 boards interchangeable?

Do not assume so. Documented examples include different revisions, including B00 and C0, and descriptions vary between controller and front-I/O functions. Match the revision and installed controller configuration before substitution.

Is New Surplus JARCR-XSC01 acceptable?

Yes. For a legacy XRC controller, a verified New Surplus board can be a practical spare. The important checks are authenticity, PCB revision, battery condition, connector condition, and controller-level functional testing.

What warranty should I request?

For New Surplus or refurbished stock, request coverage for controller initialization, communication/interface operation, board power rails, connector integrity, and functional operation in the intended XRC system. For refurbished units, ask whether the board was tested in an actual XRC controller rather than only visually inspected.
