About Mitsubishi Robots and Controllers

Mitsubishi Electric is a global leader in automation technology, renowned for its high-performance robots and sophisticated control systems. Mitsubishi robots are widely used in various industries, including automotive, electronics, food and beverage, and pharmaceuticals, for tasks such as assembly, welding, painting, and material handling. Their robot controllers are the brains behind these robots, responsible for executing complex movements, coordinating multiple axes, and ensuring precise operation.


Mitsubishi robot controllers are known for their advanced features, including real-time control, high-speed processing, and seamless integration with other automation equipment. They are designed to be robust and reliable, but like any electronic device, they can experience failures due to wear and tear, electrical surges, or environmental factors. When a Mitsubishi robot controller malfunctions, it can bring your entire production line to a standstill, resulting in significant financial losses. Roc Industrial LLC is here to help you avoid those losses with our expert repair services.

Common Mitsubishi Robot Controller Problems We Repair

Mitsubishi robot controllers are built to withstand demanding industrial environments, but they are not immune to failure. Our technicians have extensive experience troubleshooting and repairing a wide array of issues that can affect these controllers. Here are some of the most common problems we encounter:

  • Power Supply Failures: The controller fails to power on or experiences intermittent power loss. This can be due to component failure within the power supply unit.

  • Communication Errors: The controller is unable to communicate with the robot arm, teach pendant, or other devices on the network. This can be caused by faulty communication ports, damaged cables, or software configuration issues.

  • Encoder Faults: The controller reports errors related to the robot's encoders, which are responsible for providing feedback on the position of the robot's joints. This can result in inaccurate movements or complete robot shutdown.

  • Servo Amplifier Problems: Issues with the servo amplifiers that drive the robot's motors, leading to jerky movements, lack of torque, or complete motor failure.

  • CPU Failures: The central processing unit (CPU) of the controller malfunctions, causing the entire system to crash or operate erratically.

  • Memory Errors: The controller experiences errors related to its memory, such as program corruption or inability to store data.

  • I/O Module Failures: Problems with the input/output (I/O) modules that interface the controller with external devices, such as sensors and actuators.

  • Overheating: The controller overheats due to inadequate cooling or component failure, leading to performance degradation or complete shutdown.

  • Blown Fuses: Frequent blowing of fuses within the controller, indicating an underlying electrical problem.

  • Software Corruption: The controller's operating system or application software becomes corrupted, causing malfunctions or preventing the robot from operating correctly.

  • Teach Pendant Issues: Problems with the teach pendant, such as unresponsive buttons, display issues, or communication failures.
