Motor Parameter Database Fault

Was bedeutet 42 ?

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.

• Corrupted or missing motor nameplate data (e.g., P3-01 to P3-10) in the drive's non-volatile memory.
• Failed Automatic Motor Tuning (AMT) procedure resulting in incomplete or erroneous motor model parameters being saved.
• Manual entry of motor parameters that fall outside the drive's permissible ranges or contradict other settings.
• Incompatible motor connected to the drive, or motor parameters that are fundamentally invalid for the drive's control algorithm.

1. 1

   1. Carefully re-enter all motor nameplate data (P3-01 Motor rated power, P3-02 Motor rated current, etc.) according to the motor's physical label.

2. 2

   2. Perform a new Automatic Motor Tuning (AMT) procedure (Parameter P5-01 = 1) ensuring the motor is uncoupled.

3. 3

   3. Measure the motor phase resistance (ohm) between terminals U-V, V-W, W-U and compare for consistency.

4. 4

   4. Verify the motor's insulation resistance to ground (megohms) using a megohmmeter to rule out winding faults.

5. 5

   5. Replace the control card if the motor parameter database fault persists after re-entry and successful AMT.
