Fanuc PSM Alarm 01 - PSM-5.5 to PSM-11

For the PSM-5.5 to PSM-11

The main circuit power module (IPM) has detected an overload, overcurrent, or control supply voltage decrease.

1. Cooling fan failure
   1. Check whether the cooling fan rotates normally. Replace the cooling fan.
2. Dust buildup
   1. Clean the cooling system with a vacuum cleaner or compressed air.
3. Overload
   1. Examine the operating conditions.
4. Input supply voltage imbalance
   1. Check the input power supply specification.
5. The specification of the AC reactor does not match the PSM in use.
