    Re: NEW 88HS OPERATOR, NEED HELP

    If it is not positioning properly (not going far enough) then you might have a loose resolver (if DC motor) or maybe your survey is wrong (laser calibration). First thing to check is lubrication....

    Have someone come in and run a ballbar. That will tell you. It could be a number of things. Did you put brand new resolvers in? Could be just a dirty tach on the motor. Is your following error...

    Re: Fadal all axis problem

    It is most likely your DC power supply. The caps are crap and now you have a bunch of noise on your 5,12,-12 vdc supply. Chrck AC ripple on these from the DC PS. Should be lower than 10 mvAC

    You will not get an air alarm. If you try to use something that needs air you will then get a click sound in the back and then the control will say waiting on air valve. The oil tank has a float and...
  16. Re: HI and Low Piston Spindle Activated at the same time

    Is it the old mac valve with the shuttle? If so I would also check that. Also the pressure should be reduced after the tool in/out line to 80 psi. The mac valves will blow by above 120 psi.
