SINAMICS S210 F30004: Power Unit Overtemperature Heat Sink AC Inverter
What F30004 means
The S210's heat sink got hotter than its limit, so the converter shut down to protect its power stage.
Symptoms
Trips after running for a while, more often on hot days or under heavy duty cycles.
Is it repairable?
Yes: fan replacement and cleaning are simple repairs; repeated overheating can also damage the power stage.
Common causes
- Cooling fan failed or blocked (3 AC units have a fan)
- Dust on the heat sink
- Cabinet too hot or not enough space around the converter
- Overload
- Switching frequency set too high
Safe checks
- 1Check the fan turns and the airflow path is clear
- 2Clean the heat sink
- 3Measure the cabinet temperature
- 4Compare motor current with the converter rating
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
