How to deal with the abnormal elastic signal of the fourth axis of Runxing Technology

Hello, I'm glad to answer your question. Hello, 1. Check and adjust the tightness of the fastening device. 2. Check whether the proximity switch is effective. 3. Remove dust from the movable area of the clamping device. 4. Use a multimeter to confirm whether the "tightening" and "loosening" circuits are smooth and effective. 5. Call up the NC circuit diagram and confirm that the "tightening" and "relaxing" signals are effective.
