Motor Parameter Database Fault

What does 42 mean?

A fault has been detected in the motor parameter database, which stores crucial information about the connected motor. This can prevent the drive from accurately controlling the motor, potentially leading to inefficient operation, overheating, or motor damage. It implies a data integrity issue within the drive's memory.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the issue persists, perform a full drive initialization (using parameter 620) and re-enter all settings, then attempt motor tuning.

2. 4

   If the fault reoccurs, replace the control card.
