Mitsubishi Electric MRJ2S B Instruction Manual

To perform a factory reset, navigate to the parameter settings on the MRJ2S B, set the parameter "Pr. 19" to "2" and then cycle the power. This will restore all parameters to their factory defaults.
The "AL. 30" error indicates an overcurrent. Check for short circuits in the motor cables, ensure the motor is not mechanically overloaded, and verify that the drive is properly grounded.
To improve positioning accuracy, ensure the servo motor is properly aligned, adjust the gain settings in the servo parameters, and minimize mechanical backlash in the system.
Regularly inspect the cooling fans for dust accumulation, check and tighten electrical connections, and ensure the ambient temperature does not exceed specified limits. Perform these checks every 6 months.
While it is possible, it is recommended to use Mitsubishi Electric motors for optimal performance. If using a third-party motor, ensure compatibility in terms of voltage, current, and encoder feedback.
Check the communication cable for damage, verify the communication settings (baud rate, parity, etc.) match on both devices, and ensure the PLC program is correctly configured to communicate with the drive.
Contact Mitsubishi Electric support to obtain the latest firmware version and follow their provided instructions, as firmware updates may require specific tools or software.
Check the power supply connections and ensure that the input voltage is within the specified range. Inspect the fuses and replace any that are blown.
Use shielded cables for both power and signal connections, ground the system properly, and consider adding ferrite cores to cables to suppress electromagnetic interference.
Signs include unusual noises, excessive vibration, overheating, and a decrease in performance or efficiency. Regular monitoring can help identify these issues early.
