Support Request – ATV71 200kW Drive – PWR Calib (INF2) Error After Control Board Replacement

[FelixQiu]

Dear Schneider Electric Support Team,

I hope this message finds you well.

We are currently facing an issue with an ATV71 200kw 380VAC variable speed drive. The original control board (small board) was damaged, and we replaced it with a new one. However, after powering on, the drive displays the following error on the HMI: "PWR Calib (INF2)"

Interestingly, when we tested with a control board taken from another working ATV71 drive, everything worked fine and no error appeared. This suggests that the issue is related to calibration or compatibility between the new control board and the power board.

We would like to know:

1. What is the correct procedure to make the new control board compatible with the existing power board?

2. Is there a calibration or initialization process required after replacing the control board?

3. Are there any tools or software required to complete this procedure?

We would greatly appreciate your guidance or documentation on how to properly resolve this issue.

Thank you very much for your support.
