• Accurate temperature detection and early warning for potential overheating risks.

• Transmit alarm messages to the main control board when temperature exceeds limits.

• Activate safety interlock to shut down related units and avoid component damage.

• Optimized signal anti-interference for stable monitoring in complex industrial environments.

5. Differences from JANCD-MTU01

• MTU02 features more temperature sensing channels and higher detection accuracy.

• Supports adjustable alarm thresholds to fit different working conditions.

• Improved anti-interference capability for long-term stable operation.

• Pin-to-pin compatible with MTU01 and can be used as a direct replacement.

6. Compatibility

• Fully compatible with Motoman XRC and MRC robot controllers.

• Not compatible with DX, FS, YRC series controllers and non-Yaskawa equipment.

7. Installation & Safety Precautions

• Cut off all power before installation or removal. Hot swapping is forbidden.

• Wear a grounded ESD wristband to protect sensitive electronic components.

• Install the board in the designated slot and tighten fixing screws securely.

• Route sensor cables separately from high-voltage lines to reduce interference.
