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