During replacing the CRT monitor with LCD upgrade we lost our parameters, The machine was running great other than we could not view the screen. After some assistance we reloaded the parameters that the machine mfg gave us, however now if we run the controller above 4% we get follow errors for the X & Y axis theses are the only 2 axis we use. Is there a parameter that is causing these errors if they exceed a certain value? Again nothing was changed with the drives we just lost the parameters. the machine mfg stated it could be from worn motors, drives, bearings ETC, but it ran perfect before the lose of the parameters.
