South Korea KIA CNC machine tool vx380 is turned on, and the yellow light on the panel button flashes.

1, power supply problem: check whether the power supply of the CNC machine tool is normal, and confirm whether the power cord is in good contact and whether the voltage meets the standard.

2. Interface board failure: It may be the failure of the panel itself, so it is necessary to check whether the connecting wires of the panel are loose or damaged, or whether the components inside the panel are damaged.

3. Controller failure: The controller itself may be faulty, so it is necessary to check whether the connecting wires of the controller are loose or damaged, or the internal components of the controller are damaged.
