About Mitsubishi CNC Control Boards

Mitsubishi Electric is a global leader in automation and control systems, and their CNC (Computer Numerical Control) systems are renowned for their precision, reliability, and advanced features. Mitsubishi CNC control boards are the brains behind these systems, responsible for executing complex machining programs and controlling the movement of axes with utmost accuracy. These boards are integral to a wide range of CNC machines, including milling machines, lathes, machining centers, and more. They are designed to handle demanding industrial environments and provide consistent performance over long periods.


Mitsubishi CNC control boards are widely used in industries such as aerospace, automotive, medical device manufacturing, and general machining. Their robust design and advanced functionality make them a preferred choice for applications requiring high precision and complex machining operations. However, like any electronic component, these boards are susceptible to failure due to factors such as age, wear and tear, power surges, and environmental conditions. When a Mitsubishi CNC control board fails, it can bring your entire production line to a standstill, resulting in significant financial losses. Roc Industrial LLC understands the urgency of these situations and offers comprehensive repair services to minimize downtime and restore your CNC machine to optimal performance.

Common Mitsubishi CNC Control Board Problems We Repair

Mitsubishi CNC control boards can experience a variety of issues that can disrupt your CNC machine's operation. These problems can range from simple component failures to more complex system-level errors. We have extensive experience in diagnosing and repairing a wide range of Mitsubishi CNC control board problems.

  • No Power or Boot Failure: The control board fails to power on or does not boot up correctly. This can be due to power supply issues, damaged capacitors, or corrupted firmware.

  • Communication Errors: The control board is unable to communicate with other components of the CNC system, such as the servo drives, spindle drive, or operator panel. This can be caused by faulty communication chips, damaged cables, or incorrect configuration settings.

  • Axis Control Problems: Issues with axis movement, such as erratic motion, inaccurate positioning, or complete failure to move. This can be due to encoder faults, driver IC failures, or problems with the feedback loop.

  • Spindle Control Issues: Problems with spindle speed control, including inconsistent speeds, failure to start or stop, or excessive vibration. This can be caused by faulty spindle drive interfaces, damaged transistors, or issues with the speed feedback system.

  • Memory Errors: The control board displays memory errors or is unable to load or save programs. This can be due to faulty memory chips, corrupted data, or issues with the memory backup battery.

  • Display Problems: Issues with the display screen, such as a blank screen, distorted images, or flickering. This can be caused by faulty display drivers, damaged LCD panels, or issues with the video signal.

  • Input/Output (I/O) Failures: Problems with the input or output signals, such as sensors not being read correctly or outputs not activating. This can be due to faulty I/O modules, damaged connectors, or issues with the PLC interface.

  • Overheating: The control board overheats, leading to performance degradation or complete failure. This can be caused by inadequate cooling, component failures, or excessive load.

  • Blown Fuses: Repeatedly blown fuses on the control board, indicating a short circuit or overload condition. This requires careful diagnosis to identify the root cause of the fault.

  • Encoder Faults: Errors related to the position encoders, leading to inaccurate positioning or axis movement. This can be due to faulty encoder chips, damaged encoder cables, or issues with the encoder interface.
