Frequency Upper Limit Exceeded

What does 001 mean?

This warning indicates that the parameter set for the frequency upper limit (A061) is configured to a value higher than the inverter's maximum allowed frequency (A004). This inconsistent setting may lead to unexpected operational limits or prevent the drive from reaching its full potential.

• Inadvertent manual input of A061 (Frequency Upper Limit) to a value greater than the drive's inherent maximum frequency (A004).
• Software bug or corrupted parameter memory leading to an incorrect default value for A061 after a reset or firmware update.
• Restoration of an incompatible parameter backup from a different drive model with a higher A004 setting.

Click steps to track your progress.

1. 1

   Access parameter A061 (Frequency Upper Limit) and compare its value to A004 (Inverter Max Allowed Frequency).

2. 2

   Set A061 (Frequency Upper Limit) to a value equal to or less than A004 (Inverter Max Allowed Frequency). A common practice is to set A061 to match A004 for maximum allowable speed.

3. 3

   Confirm that the new setting for A061 is stored by powering the drive off and on, then verifying the parameter value again.

4. 4

   If the issue persists, perform a parameter reset to factory defaults (e.g., P0-01 set to "99") and then re-enter all necessary application parameters carefully.
