Data Values Error (EEPROM)

Was bedeutet 41 ?

This fault indicates an error within the data values stored in the EEPROM. This memory holds configuration settings and operational data, and corruption can lead to the drive operating with incorrect parameters or failing to start. It points to a memory integrity issue on the control card.

• Corruption of user-defined configuration parameters (e.g., motor data, acceleration/deceleration times) in EEPROM during power loss.
• Failed attempt to save parameters (e.g., due to an 'Enable Save' interlock not met or a communication timeout).
• Incompatible or malformed configuration file loaded into the drive, leading to data integrity issues.
• Degradation of the EEPROM memory cells, causing bit errors in stored data values.

1. 1

   1. Reset the drive to factory default settings (Parameter P1-00 = 1) and re-enter all necessary application parameters.

2. 2

   2. Load a previously known-good configuration file from a backup source (e.g., via a drive software tool).

3. 3

   3. Verify individual critical parameters (e.g., P3-02 Motor rated current, P1-20 Acceleration time) for correctness after entry.

4. 4

   4. Measure the auxiliary control card power supply voltage for any fluctuations that could affect EEPROM write operations.

5. 5

   5. Replace the control card if data value errors in the EEPROM persist after reset and parameter re-entry.
