1. Mitsubishi servo drive alarm code AL31.1

Fault analysis: It is the motor overspeed alarm.

Cause analysis: 1. The frequency of the single pulse of the typed command is too high;

2. The acceleration and deceleration time is too small, resulting in overshoot and too large;

3. Mitsubishi servo system is unstable;

4. The ratio of electronic transmission gears is very large;

5. The Mitsubishi servo encoder is abnormal;

Mitsubishi servo motor alarm code and processing skills

Matching processing method: 1. Set the appropriate single pulse frequency;

2. Extended addition and subtraction time constant;

3. Set the gain value again;

4. Set the appropriate electronic transmission gear ratio;

5. Disassemble and replace Mitsubishi servo encoder or Mitsubishi servo motor;

2. Mitsubishi servo drive alarm code ALE6.1

Problem analysis: It was the Mitsubishi servo motor that stopped in an emergency

Cause analysis: The route between the Mitsubishi servo drive EMG and the SG center is broken

Matching solution: Just short circuit the EMG

3. Mitsubishi servo drive alarm code AL52

Fault Analysis: The dwell single pulse in the error electronic counter exceeds the working capacity of the Mitsubishi servo encoder pixels multiplied by 10

Cause analysis: 1. The scale setting of acceleration and deceleration time constants is unscientific;

2. The constraint value of rotation distance is very small;

3. Due to the decrease of the working voltage of the switching power supply, the motor rotation distance is not enough, and the servo motor cannot be started;

4. The gain value of the azimuth ring 1 is very small;

5. The servo motor shaft rotates due to external force;

6. Equipment faults;

7. Encoder fault.

Matching treatment methods: 1. Set the appropriate acceleration and deceleration time constant (please refer to the Mitsubishi servo motor manual);

2. Extended rotation constraint value;

3. Disassemble and replace the Mitsubishi servo motor with larger output power;

4. Adjust the preset value to the level where the Mitsubishi servo system can operate normally;

5. Extend the rotation constraint value, reduce the load or choose to output a larger Mitsubishi servo motor

6. Install the travel switch after checking the operation method

7. Disassemble and replace the Mitsubishi servo encoder or Mitsubishi servo motor
