ope01 fault in yaskawa drive indicates a Drive Unit Setting Error. This means the rating in control card is different from power card rating.

This error often arises due to a "mismatch between the drive's capacity and the setting in parameter o2-04, which defines the drive model (KVA) selection".

Common Causes and Solutions:

  1. Incorrect KVA Setting:

    • Verify the Setting: Double-check the value set in parameter o2-04 to ensure it accurately reflects the drive's actual KVA rating.
    • Correct the Setting: Use the drive's programming software or keypad to adjust the o2-04 parameter to the appropriate value.
  2. Control Board Replacement:

    • Factory Default Settings: If the control board has been replaced, it may have default settings that need to be adjusted.
    • Check Parameter Settings: Review all relevant parameters, including o2-04, to ensure they are correctly configured.
  3. Hardware Issues:

    • Inspect for Damage: Visually inspect the drive for any signs of physical damage, such as loose connections or burnt components.
