The message "F2AL" Motor frequency low threshold 2 reached indicates a fault condition in Schneider ATV950 drive related to the motor's operating speed dropping below a specific limit.

"F2AL" "Motor frequency low threshold 2 reached" warning in Schneider ATV950 drive indicates that the motor frequency has dropped below a second predefined low threshold limit set in the drive's parameters.

1. This typically represents a more severe or critical condition compared to the first threshold and requires prompt attention.
2. Examine the load on the motor. Insufficient or sudden decreases in load can cause the motor frequency to drop.
3. Verify that control signals to the drive are stable and within expected ranges. Erratic control signals can cause frequency fluctuations.
