The YASKAWA JANCD-XTU01B is a specialized power-on circuit board used primarily within the Motoman XRC series robot controllers.

It is a critical component for the control rack’s power distribution and system initialization logic.

1. Introduction

The JANCD-XTU01B (often identified by part number 142150-1) is the Power On Board for the XRC controller.

Its primary role is to manage the power-up sequence of the controller rack, monitor system voltages, and interface with the emergency stop and power control circuits.

It ensures that the sensitive CPU and I/O boards receive stable power before the robot’s motion systems are energized.

3. Product Advantages and Features

System Protection: It acts as a gatekeeper, preventing the robot from operating if the internal power supply or safety string (E-stop) is compromised.

LED Status Indicators: Features onboard diagnostics to help maintenance teams verify if the board is receiving power and if the “Ready” state has been achieved.

Revision Stability: The “B” version (and subsequent revisions like Rev. E) includes improved noise filtering and circuit protection over the original XTU01.

High Reliability: Built to industrial standards to operate 24/7 in harsh manufacturing environments with high electromagnetic interference (EMI).

4. Application Cases

The JANCD-XTU01B is an essential internal component for any application using an XRC controller, including:

Automotive Assembly: Controlling power sequences in multi-robot welding cells.

Semiconductor Manufacturing: Providing stable power for high-precision wafer-handling robots.

General Industrial Automation: Integrated into palletizing, packaging, and CNC tending systems where the XRC controller platform is utilized.

5. Other Models in the Same Series

This board works in conjunction with other specific XRC series modules. Common related boards include:

JANCD-XTU01: The earlier iteration of the power-on board.

JANCD-XIO01B: The standard digital I/O interface board (as discussed previously).

JANCD-XCP01: The main CPU board that coordinates with the XTU01B during the boot sequence.

JANCD-XSP01B: The system processing board used for motion control tasks.

JANCD-XIF03 / XIF04: External interface/communication boards.
