Drive: Incorrect control parameter

Was bedeutet F07080 ?

One or more closed-loop control parameters have been parameterized incorrectly, such as setting p0356 (L_spread) to 0. The fault value (r0949) indicates the specific parameter number involved, which can vary for vector drives or synchronous motors. Incorrect parameters can lead to unstable operation, poor performance, or drive malfunction.

• Closed-loop controller gain parameters (e.g., P1460 (Speed controller P gain), P1462 (Speed controller I gain)) set to excessively high values, causing instability or calculation errors.
• Motor identification or control parameters (e.g., P0340 (Motor identification type), P0341 (Motor data), P0342 (Motor data for ID)) incorrectly entered or not optimized.
• Specific control loop parameters, such as P0356 (L_spread) in sensorless vector control, set to an invalid value like 0.
• Encoder resolution or direction parameters (e.g., P0408 (Encoder pulses), P0410 (Encoder direction)) misconfigured, causing feedback calculation errors.

1. 1

   1. Read parameter r0949 to identify the specific parameter causing the fault.

2. 2

   2. Verify the value of the parameter indicated by r0949 against recommended ranges or application notes in the drive manual.

3. 3

   3. Perform a motor identification run (e.g., set P0340 = 1) if the fault is related to motor model parameters, ensuring the motor is uncoupled.

4. 4

   4. Reset drive parameters to factory default (P0010 = 30, P0970 = 1), then reconfigure essential motor and application parameters.

5. 5

   5. Adjust specific control loop gains (e.g., P1460 (Speed controller P gain)) to lower, stable values if the fault occurs during tuning.
