The closed-loop control parameters of the drive have been incorrectly parameterized, for example, parameter p0356 (L_spread) is set to 0. The fault value (r0949) includes the specific parameter number that is involved. This fault does not cause an immediate reaction but requires a POWER ON acknowledgement after correction.
Click steps to track your progress.
1. Identify the specific parameter indicated by r0949 and verify its current setting against the recommended value in the drive manual or commissioning guide.
2. Perform a factory reset (e.g., P0010 = 30, P0970 = 1) and re-enter essential motor and application data, then re-commission the drive.
3. Load a known good parameter set for this specific machine and drive configuration from a backup file (e.g., using STARTER or Startdrive software).
4. Re-run the motor identification and optimization routine (e.g., P1910 = 1 for automatic tuning) to recalculate control loop parameters.
5. Check for and install any available firmware updates for the drive unit, then re-commission the drive if necessary.
