Fault Description: When the servo system is turned on, if the input voltage is lower than the normal working voltage, the system will automatically stop working and the operation panel will display.

Troubleshooting:

City network voltage is too low

1.Use a multimeter to check if the power supply voltage is lower than 220V±20%. If the voltage is too low, it is recommended to improve the grid voltage.

2. System board component damage

If the grid voltage is normal, the system board components are damaged. Please replace the motherboard.
