Parameter fault

What does PR mean?

This fault indicates an inconsistency or error within the drive's stored parameter settings. This could be due to corrupted data, an invalid parameter value, or an incorrect parameter set loaded. By default, this condition is configured as a Warning, meaning it alerts the operator and is logged, but it does not immediately inhibit pulses. Incorrect parameters can lead to improper drive operation or damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Reload factory defaults: If unsure, reload the drive's factory default settings and then re-enter application-specific parameters.

2. 4

   Check parameter save integrity: Ensure parameters are saved correctly after changes using the appropriate save function (e.g., C003).

3. 5

   Compare current parameters to a backup: If a backup of known good parameters exists, compare and correct discrepancies.
