Hello Sir

This can help you to solve the problem.

And look at the software in the display are very important!

0341
IQ MISMATCHED (left traction logic unit - master microcontroller)
Circumstances of error detection
The left traction logic unit (AU2) has detected a problem with the configuration of parameters stored in memory.
Actions:
? Run a key reset and check the correct value of the drive parameters on the display
? Eseguire un reset dell'unità logica trazione sinistra utilizzando la funzione TO DEFAULT SET
? Update the software version of the MASTER and SLAVE microcontroller on the left traction logic unit
? The insulation of the left drive motor (see paragraph INSULATION CHECK PROCEDURE):
If the measured value is less than 1MO replace the motor
Self-diagnostic
? Invert the right traction logic unit and the left traction logic unit
? Reset both logics (MENUETC - TO DEFAULT SET) and repeat the potentiometers calibrations:
? If the fault code changes from 0341 to 0241, replace the traction logic unit originally on the left
? If the fault code remains 0341, the cause of the fault is outside the left traction logic unit
