Cause : High flow error comes when the high flow monitoring function has detected an error. This could be due to several factors including sensor malfunction, incorrect configuration, or actual abnormal flow conditions.

The "HFPF" high flow monitoring function detecting an error on a Schneider ATV610 drive indicates High flow error. This means that the drive has recognized an anomaly in the flow rate being monitored.

1. Verify that the system works in its flow capabilities.
2. Verify that there is no pipe burst at the outlet of the system.
3. Verify the settings of the monitoring function.
