כיצד לפתור את אזעקת הציר של Fanuc SP9031? יִשְׂרָאֵל

Fanuc CNC controls are an essential part of your production line, and the reliability of your Fanuc system has a direct impact on efficiency and throughput. However, it is inevitable that even the most advanced CNCs will experience occasional alarms that can affect operations. One such issue is Fanuc spindle alarm SP9031, and in this article we aim to provide you with a guide to help you understand and resolve alarm SP9031 in your Fanuc system.

How to Troubleshoot SP9031 Alarm in FANUC Machine Systems

When Fanuc machine system alarms, one of the alarms is the SP9031 alarm, the other is the spindle alarm triggered by the PMC alarm, then you need to solve the SP9031 alarm, let's take a look at the detailed description of the SP9031 alarm:

Alarm cause: the motor can not rotate at the commanded speed, but stop, or rotate at a very low speed.

(1) Alarm occurs when rotating at very low speeds

a. Parameter setting is incorrect. (Refer to the FANUC AC SPINDLE MOTOR Parameter Sheet (B-65280CM) to confirm the parameters set by the sensor.)
b. Motor phase sequence error Check that the motor phase sequence is not incorrect.
c. Motor feedback cable error. Check that the A/B phase signals are not reversed.
d. Motor feedback cable error. Rotate the motor by hand and check whether the motor speed is displayed on the diagnostic switching surface of the NC or on the spindle inspection board. If the speed is not displayed, replace the cable or spindle sensor (or motor).

(2) Alarm occurs when there is no rotation at all.

a. The spindle is locked in the wrong order. Confirm that the spindle is locked in the wrong order.
b. Power cable failure. Check that the motor power cord is properly connected.
c. SVPM is defective. Replace the SVPM.

Proactive Measures to Prevent Future SP9031 Alarms

Preventing Alarm SP9031 from occurring in the future is just as important as solving the current problem. By taking proactive measures, you can maintain the efficiency and reliability of your FANUC system while minimizing downtime. Here are some key steps to consider:

Regular maintenance and inspections:
Schedule regular maintenance inspections to identify and address wear and tear on spindle components such as bearings, belts, and sensors.
Perform routine cleaning to remove debris, dust and oil buildup that may be impeding system performance.
Check spindle motor alignment to ensure it remains within the manufacturer's specified tolerances.
מעקב אחר פרמטרי מערכת:
Use FANUC's diagnostic tools to monitor the performance of the spindle motor and associated drives.
Watch for abnormal vibration, temperature changes, or power consumption levels, as these can be early indicators of potential problems.
Record alarm codes and their resolution to identify recurring problems that may require a more comprehensive solution.
Upgrade system components:
Replace outdated or worn spindle motors, drives, or connectors with newer, more reliable models.
