Power unit: Internal fan faulty
Siemens · SINAMICS G120C Variable Speed Drive
Hva betyr F30059 ?
The internal cooling fan of the power unit has failed and is likely defective. Proper cooling is crucial for maintaining the power unit's operational temperature. A malfunctioning fan leads to inadequate heat dissipation, risking severe overheating, thermal trips, reduced performance, and potentially permanent damage to the power unit if not replaced.
Vanlige årsaker
- Mechanical failure of the fan motor (e.g., seized bearings, broken blades, excessive vibration).
- Disconnection or damage to the fan's power supply or feedback wiring, preventing operation or status reporting.
- Obstruction (e.g., dust, debris, foreign objects) preventing the fan from rotating freely, leading to overload and eventual failure.
- Accumulation of dirt or dust on the fan blades, reducing cooling efficiency and potentially causing motor strain.
Reparasjonssteg & Sjekkliste

- 1
Visually inspect the power unit's internal cooling fan(s) for physical damage to blades or accumulation of dust/debris.
- 2
Check the fan's electrical connection to the power unit's control board for looseness or corrosion.
- 3
Attempt to manually rotate the fan blades (with power off) to check for free movement and absence of obstructions.
- 4
Measure the fan's supply voltage (e.g., 24VDC or 48VDC) at its connector when the drive is commanded to run.
- 5
Replace the internal cooling fan unit with an OEM approved spare part.
