    Alarm for stroke check prior to movement.
    The end point specified in a block falls within the forbidden area defined with the stroke check in the negative direction along the X axis.
    Correct the program.

    Hi still have the same problem. For example if I turn ON the machine and want to do Homing I would need to move the X axis in -X direction to home it with +X. But alarm 511 doesnt let me. I can move the motor in -X direction by hand when the machine is OFF away from the Homing switch and then I can do Homing for all the axes but alarm still stays ON and I am unable to move the machine in -X direction. Machine also has Absolute encoders installed. Any help would be appreciated. Thank you.

    ...faulty Limit switch -X most likely. . Coolant, Oil, Dirty, or Old age Micro switches do not last for ever..

    I solved the problem by changing the parameter for homing for X axis.
