Cause: High speed reached comes when the motor connected to the drive has reached its maximum permissible speed while drawing full load current. This warning typically comes when the drive might have incorrect motor data configured, leading to inaccurate speed calculations.

"FLA" "High Speed Reached" warning in a Schneider ATV950 drive indicates that the drive has reached or exceeded its maximum configured speed. This can be a result of various factors, including an incorrect speed reference, a malfunctioning feedback device, or a configuration issue.

Here are the steps to address the FLA warning:

1. Check Speed Reference:

   • Verify the speed reference input to the drive. Ensure that it is within the allowable range and is correctly configured.
   • Check any external devices providing speed commands to ensure they are operating correctly and providing the correct signals.

2. Inspect Feedback Devices:

   • If the drive uses an encoder or other feedback device for speed control, verify that the feedback device is functioning correctly.
   • Check the wiring and connections of the feedback device to ensure they are secure and undamaged.

3. Review Drive Configuration:

   • Access the drive’s configuration settings and verify that the maximum speed settings are correctly configured. Ensure that they match the requirements of your application.
   • Check the scaling and limits configured in the drive’s settings.

4. Monitor Load Conditions:

   • Examine the load connected to the drive. An unexpected load condition or a mechanical issue could cause the drive to reach high speeds.
   • Ensure that the mechanical system is operating within its designed parameters and there are no faults or issues.

5. Check for Overvoltage:

   • High speeds can sometimes be associated with overvoltage conditions. Check the drive’s voltage settings and the incoming power supply.
   • Verify that the power supply is stable and within the specified range for the drive.
