Can't set magnetizing inductance

What does 4074 mean?

The drive is unable to determine or set the motor's magnetizing inductance (Lm). This is typically caused by incorrect motor data entered into the drive, which is crucial for accurate motor modeling and control calculations.

• Incorrect motor data entered in the drive parameters, specifically affecting inductance calculations.
• Motor model or type incompatible with the drive's internal magnetizing inductance identification routine.
• Incomplete or failed motor identification process.
• Parameter limits or ranges being exceeded during the Lm calculation.

Click steps to track your progress.

1. 1

   Check all motor data parameters (e.g., rated voltage, current, frequency, power) for accuracy against the motor nameplate.

2. 2

   Verify that the selected motor type is compatible with the drive's magnetizing inductance estimation algorithms.

3. 3

   Re-run the motor identification or autotuning process after carefully reviewing and correcting motor data.

4. 4

   If manual entry is an option, ensure that the magnetizing inductance value, if known, is within acceptable limits.
