    Hello Sir;

    Encoder on the first unit - used for exact position during plate changing

    Hello,
    It is an old Machine KBA 2000 /RA162A-6 + LPWVA ALV3. this machine has a single encoder installed in the Operator side in the first printing Unit.
    I have change this encoder with a new too, but I have the same problems exactly .
    Thanks for your responses.

    Good job....
    The most common issue is the tacho-generator and you said that has been changed with the brake.
    Is the brake adjusted correctly ?

    Thank you for your responses
    I have adjusted the new brake through its adjustment screw (micro switch).
    Because I have another problem before the change of the brake (brake unclamped) ; when I start the plate change program.
    This problem is solved but the others problems not yet.
    I have change the encoder and module inside main cabinet AK40; but no chance.
