    Have you checked the jog feedrate switch position????? Or maybe this switch is bad.

    GP.

    Sorry, your jog feedrate switch must be ok if it moves to the positive direction. If the problem is in the parameters you must check the stroke limit param. These parameters are no. 5220 to 5225.

    Good Luck.

    GP.

    GP,
    Thanks, we found our problem, it was a faulty tool presetter not allowing us to move in a negative direction.
