40

Calibration Constant Error (EEPROM)

Danfoss · VLT 2800 Variable Speed Drive

What does 40 mean?

An error has been detected in the calibration constants stored in the EEPROM. These constants are vital for accurate measurement and control, and any discrepancy can lead to incorrect drive outputs, poor motor control, or misinterpretation of sensor data. This suggests data corruption or a hardware issue with the EEPROM.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    If the problem persists, replacement of the control card is required as calibration constants are stored within its EEPROM.
