    Hello
    Does anyone has the electronic schematics of Dahlgren DC drive forofor dampening and ink motor of ZirkonSupra@ 660 ?
    The drive is DDR production 220 EGGh 180/10
    I have a very strange problem. When I start the press the motor is turning smoothly. When I speed up to print, the motor start to run in impulses then again smoothly for few seconds then again impulses and so on, although the speed signal from the press is stable. But some voltages on the drive are oscillating like crazy. And all the drives behave in the same way like they are synchronized.
    Any ideea will help.

    Thanks
