Hi folks

I'm having a hard time trying to configure my HY VFD.

Everything seems normal (after starting the VFD, I can start the spindle, change its speed...)

But when I want to program it : I press Program, I can change the number of the parameter, and when I click on "SET", nothing happen.
I can't acces the value of any parameters.

I've search this problem on the web, can't find any response.

Is the unit locked ?
Is there like a "hard" reset that I can do ?
Do you think my unit may be defective ?

Thank you !!

I understand that if it was password protected, it would ask for a password..

I've checked inside the control panel, the press button for SET works fine, and no components seem damaged (I've tested some diodes and resistors on the path of the button to the microcontroller)
i'm stucked
