Frequency Lower Limit Exceeded

Hva betyr 002 ?

This warning indicates that the parameter set for the frequency lower limit (A062) is configured to a value higher than the inverter's maximum allowed frequency (A004). This inconsistent setting creates a logical conflict in the drive's operational range.

• Erroneous manual entry of A062 (Frequency Lower Limit) to a value exceeding the drive's absolute maximum frequency (A004).
• Parameter configuration error where A062 was mistakenly set to the same value as A004, or even higher.
• Restoration of an incorrect parameter file that contains an illogical setting for A062.

1. 1

   Access parameter A062 (Frequency Lower Limit) and compare its value to A004 (Inverter Max Allowed Frequency) and A061 (Frequency Upper Limit).

2. 2

   Set A062 (Frequency Lower Limit) to a value less than or equal to A061 (Frequency Upper Limit) and also less than or equal to A004 (Inverter Max Allowed Frequency). A common starting point is 0 Hz or a very low value.

3. 3

   Verify the motor's minimum operating frequency requirements for the application and configure A062 accordingly, ensuring it does not exceed A061.

4. 4

   Save the parameter changes and power cycle the drive. Then re-check the value of A062 to ensure it has been correctly stored.
