Yaskawa XCP02B XRC Sensor Board

Description

Key Technical Specifications

Public spare-parts references identify XCP02B as an “XRC Sensor Board/COM ARC,” while separate listings identify JANCD-XCP02B-1 as an XRC sensor board for seam tracing.

Product Introduction

The is a legacy Motoman XRC controller PCB associated with sensor and arc-related functions. References for the full designation specifically associate the board with XRC sensor/seam-tracking applications. It is therefore important to treat as a controller-board identifier rather than as a generic PLC or CPU module.

A critical procurement issue is the suffix. is separately identified as a conveyor-tracking board, including descriptions of panel-mounted, multi-channel conveyor tracking hardware. It should not be assumed interchangeable with the /-1 sensor or seam-tracking configuration.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation (~5 minutes)

1. Apply the robot cell’s lockout/tagout procedure.
2. Record the XRC controller model and software revision.
3. Photograph the existing board and all connected cables.
4. Record the complete part number, including JANCD-, suffix, and revision.
5. Document connector positions and cable routing.
6. Prepare ESD protection, a PH1 screwdriver, labels, and a multimeter.
7. Preserve the original board until the replacement has completed testing.

⚠️ Do not order solely from “.” Verify whether the installed board is , another revision, or the distinct variant.

Stage 2 — Removing the Existing Board (~5 minutes)

1. Shut down the Motoman controller according to the maintenance procedure.
2. Isolate the controller from its electrical supply.
3. Confirm that residual electrical hazards have been addressed.
4. Label every connector before removal.
5. Disconnect the cables without stressing the PCB connectors.
6. Release the board mounting hardware.
7. Remove the PCB using ESD precautions.
8. Inspect connectors, sockets, and the controller backplane for contamination or damage.

Keep the removed PCB available as the physical reference until the replacement has passed commissioning.

Stage 3 — Installing the Replacement (~5 minutes)

1. Compare the replacement PCB against the removed board.
2. Verify the complete identification and revision.
3. Check connector locations and board markings.
4. Install the PCB without forcing the edge connector or mounting hardware.
5. Secure the board using the original mounting hardware.
6. Reconnect each cable according to the photographs and maintenance documentation.
7. Inspect the completed installation for loose connectors or trapped wiring.

⚠️ Do not substitute a JANCD–2 merely because the base designation matches. The available documentation associates the -2 board with conveyor tracking rather than the XRC sensor/seam-tracking function.

Stage 4 — Power-On & Functional Testing (~10–15 minutes)

1. Perform a final wiring and connector inspection.
2. Verify that no loose hardware remains inside the controller.
3. Restore power according to the XRC maintenance procedure.
4. Check controller alarms and board diagnostics.
5. Verify the relevant sensor or arc-related function.
6. For seam-tracking applications, perform a controlled dry-run before production welding.
7. Confirm that the robot responds correctly to the sensor input.
8. Record controller alarms, software revision, and replacement-board revision.
9. Retain the failed PCB for comparison if intermittent faults remain.

Technical Pitfall & Survival Guide

The biggest replacement mistake is confusing the family variants.

Yaskawa/Motoman spare-parts references separately identify:

• — XRC sensor board / seam tracing.
• — conveyor tracking / automation conveyor tracking.
• — commonly used as the shorter XRC sensor board / COM ARC designation.

A board can physically fit and still be the wrong functional variant. On legacy Motoman equipment, the complete JANCD part number and PCB revision should be treated as procurement-critical information.

Frequently Asked Questions (FAQ)

What is the Yaskawa ?

The is a Yaskawa Motoman XRC controller PCB associated with sensor and arc-related functions. References specifically identify the as an XRC sensor board/COM ARC and associate JANCD–1 with sensor/seam-tracing applications.

Is a CPU board?

It should not be treated as the main XRC CPU simply because it is a controller PCB. Available references classify as an XRC sensor/arc-related board. The XRC system’s exact board architecture should be checked against the controller’s hardware documentation.

What is the difference between -1 and -2?

They serve different functions. is identified with XRC sensor/seam-tracing applications, whereas is identified with conveyor tracking. They should not be assumed to be interchangeable.

Is obsolete?

belongs to the legacy Motoman XRC ecosystem, and current replacement-market references exist for JANCD–1 and -2. However, “obsolete” should be confirmed against Yaskawa’s lifecycle documentation for the specific controller and board revision rather than inferred solely from third-party availability.

Can I replace an directly?

Only after verifying the complete part number and application. Check the existing board’s JANCD designation, suffix, revision, connectors, XRC controller model, and installed sensor/arc or seam-tracking configuration. A matching base name alone is not sufficient.

What should I provide when sourcing an replacement?

For a high-confidence match, provide:

• Complete PCB label
• JANCD number
• Board revision
• Controller model
• Front and rear PCB photographs
• Connector photographs
• Existing application: seam tracking, arc sensing, or another function

This is particularly important because -1 and -2 have different documented applications.
