Fan is not operating correctly (_ecFAN_LOSS)
ABB · ACS850 Standard Program Firmware
¿Qué significa 30010 ?
The drive has detected a failure of its internal cooling fan. This means the drive is not being adequately cooled, and continued operation risks severe over-temperature conditions, leading to damage to internal components.
Causas comunes
- Fan motor seized or bearings worn out, preventing rotation.
- Fan power supply (e.g., 24VDC) on the drive's control board has failed.
- Fan control circuit or sensor on the drive's main board is malfunctioning.
- Accumulation of dust and debris on fan blades, increasing friction and impeding rotation.
- Loose or disconnected fan wiring harness inside the drive.

1. Power down the drive and visually inspect the fan blades for physical obstructions or damage.
- 2
2. Gently try to rotate the fan blades manually (with power off) to check for seizure or excessive resistance.
- 3
3. Verify the fan's electrical connection to the drive's control board is secure and free from corrosion.
- 4
4. With the drive powered on (and fault cleared if possible), observe if the fan spins during operation or when commanded (if controllable).
- 5
5. Measure the voltage at the fan's terminals on the control board (if accessible and safe) to confirm power supply.

6. Replace the internal cooling fan if visual inspection or power checks indicate mechanical or electrical failure of the fan unit itself.
