    Default QM-46-2 - Speed Control Problem

    Hi Everyone,

    We have a 1997 QM-46 that is have speed setting problems. The press will startup fine at a low speed and we can ramp it up to a certain point. At that point the press will no longer speed up or slow down, even though the console show the speed changing. If we change the speed to be very slow the press will just shut down.

    Heidelberg says it can be the motor, the power supply (which is a series of three boards), or on part number that we can not locate at all.

    Has anyone had this problem? And if so what was the actual problem.

    Thank you
