Can't set flux control integral gain

Hva betyr 4071 ?

The drive is encountering an issue when attempting to set the integral gain for the flux control loop, even though the API may not report a direct error. This suggests an underlying problem with the motor data or internal drive settings, hindering proper and stable flux control.

• Inconsistent or unstable motor data parameters (e.g., P2-01 to P2-05) are causing the flux model calculation to fail silently.
• Electrical noise or transient disturbances are affecting the drive's internal control calculations during the flux integral gain setting process.
• Drive internal memory corruption or a transient software error during parameter write operations for flux control (e.g., P7-11 Ki_flux).
• Motor circuit parameters (e.g., P2-06 stator resistance, P2-07 leakage inductance) are inconsistent with the drive's expected range for the chosen motor type.

1. 1

   Cross-reference and re-enter all motor nameplate data (P2-01 to P2-05) to ensure accuracy and consistency.

2. 2

   Execute a full autotuning sequence for the motor from scratch, ensuring initial parameter identification is successful.

3. 3

   Verify the integrity of the motor cable connections at both the drive output terminals (U, V, W) and the motor terminal box.

4. 4

   Check for stable and correctly filtered supply voltage to the drive's control power input (e.g., 24VDC for the control board).

5. 5

   Attempt a soft reset of the drive (e.g., P0-00=0 then P0-00=1) to clear any transient software states before re-attempting autotuning.
