Can't set flux control proportional gain

Was bedeutet 4070 ?

The drive is unable to set the proportional gain for the flux control loop. This issue typically stems from incorrect motor data or internal drive parameter conflicts, which can prevent the drive from achieving stable and efficient flux control, impacting motor performance.

• Incorrect motor nameplate data (e.g., P2-01 rated current, P2-02 rated voltage) is entered, leading to an invalid flux model calculation.
• Drive's internal software or firmware issue preventing proper writing to flux control proportional gain parameters (e.g., P7-10 Kp_flux).
• A previous failed autotuning attempt left the flux control loop parameters in an unstable or undefined state.
• Motor equivalent circuit parameters (e.g., P2-06 stator resistance, P2-07 leakage inductance) are outside acceptable ranges for the drive's control algorithm.

1. 1

   Verify all motor nameplate data parameters (P2-01 to P2-05) are accurately entered into the drive configuration.

2. 2

   Attempt a factory reset of the drive (e.g., P0-00=1) followed by re-entering motor data and attempting autotuning again.

3. 3

   Manually inspect the flux control proportional gain parameter (e.g., P7-10) for unusual values or range limits if available for manual adjustment.

4. 4

   Perform a stator resistance measurement of the motor windings using a low-resistance ohmmeter and update parameter P2-06 if necessary.

5. 5

   Update the drive firmware to the latest stable version available from the manufacturer to resolve potential software bugs.
