You will have to post pictures and give more info in order to get some help.

They're maybe a couple hundreds of resistors in these VFD.

First power the VFD up with no motor connected and see what error is shown, if any.

hi there,
when power up the vfd no errors. when i press run with no motor connected,
everything goog , but when i press run with the motor connected
vfd shows me E.OC.A error.
i´ve already tried to solder the 2 burned resistors but the burn again...
and i dont know if the motor is in shortcut or if the problem is in the vfd.
thanks
