Cause : Initialization Required comes when the drive, control board, or terminal board have been replaced and the parameter settings between the control board and the terminal board no longer match.
An oPE04 error code in a Yaskawa drive indicates an initialization required condition. This means the control board and terminal board in the drive have mismatched parameter settings.
Here's a breakdown of what the error signifies and how to troubleshoot it:
Cause of oPE04 Error:
- The oPE04 error typically occurs when one of the following scenarios happens:
- Control Board Replacement: If the control board in the Yaskawa drive has been replaced with a new one, the new board's parameters will be blank by default. This can cause a mismatch with the existing parameters stored on the terminal board.
- Terminal Board Issue: In rare cases, a problem with the terminal board itself could lead to corrupted or invalid parameter data, causing a mismatch with the control board.
Symptoms of oPE04 Error:
- The drive will likely not function properly and might display an error message or code indicating oPE04.
Troubleshooting Steps:
Here's how to resolve the oPE04 error in a Yaskawa drive:
- Access Programming Menu: Navigate to the programming menu on the Yaskawa drive's interface (refer to your specific drive's manual for instructions on accessing the menu).
- Set Parameter A1-03: Locate parameter A1-03 in the programming menu. This parameter controls how the drive handles parameter settings.
- Transfer Parameters (Value: 5550): Set the value of parameter A1-03 to 5550. This instructs the drive to transfer the parameter settings stored on the terminal board to the control board.
- Verify and Save: After setting A1-03 to 5550, the drive might prompt you to confirm the operation. Verify and save the changes.
- Power Cycle (Optional): In some cases, after the parameter transfer, you might need to power cycle the drive (turn it off and on again) for the changes to take effect.
