Mitsubishi Electric MRJ2 C Instruction Manual

To perform a factory reset on the MRJ2 C, turn off the power, then press and hold the 'SET' and 'MODE' buttons simultaneously while turning the power back on. This will reset the drive to its default parameters.
An 'AL.13' error indicates an overcurrent issue. Check for short circuits or grounding faults in the motor cables, and ensure that the motor is not mechanically obstructed.
Servo gain settings can be adjusted using the parameter unit. Navigate to the gain parameter group and modify the proportional, integral, and derivative gains according to your application's requirements.
Regularly inspect the servo drive for dust accumulation and clean it using compressed air. Check all electrical connections for tightness and inspect cables for wear or damage.
Use the RS-485 or RS-232 communication ports on the MRJ2 C to connect to a PLC. Configure the communication parameters such as baud rate, parity, and stop bits to match the PLC settings.
Common causes of vibration include misalignment of the motor and load, imbalanced load, or incorrect gain settings. Ensure proper mechanical alignment and adjust gain settings if necessary.
To update the firmware, connect the servo drive to a computer via the communication port. Use the manufacturer's software to upload and apply the firmware update. Ensure power stability during the process.
Check the main power supply and ensure all connections are secure. Verify that the circuit breakers or fuses are not tripped or blown. If the issue persists, consult the service manual.
Set the operation mode to 'Position Control' in the parameter settings. Configure the target position, speed, and acceleration parameters as per the application requirements.
Always power off the drive before maintenance or inspection. Avoid touching the heat sink and power terminals immediately after operation due to high temperatures. Use appropriate ESD protection when handling.
