Cause : Chip overtemperature comes when the chip temperature of the semiconductor has exceeded the permissible limit value. This fault comes due to insufficient cooling, fan failure or ambient temperature too high.

F30025 fault in siemens 6RA80 DC Drive indicate Chip overtemperature. This means the central processing unit (CPU) or another critical chip within the device is exceeding its safe operating temperature. This can lead to performance degradation, system instability, or even permanent damage to the hardware.

1. Adapt the load duty cycle.
2. Check whether the fan is running.
3. Check the fan elements.
4. Check whether the ambient temperature is in the permissible range.
5. Check the motor load.
