can anyone help with recent problem on my acramatic 2100, the z axis does not operate manually , but z axis operates in programme mode and when input in mdi mode. The z does not move downwards on feed button on pendant , but does return home, the z light on pendant is frozen and x,y buttons cannot be illuminated, also the data reset button cannot be acessed. Ive checked the axis inhibit and they are fine, when machine first powers on the z axis on the pendant says - not ready, then after alligenment the z axis on pendant screen says EOP? Could the pendant be faulty? any help would be much appreciated, thanks.
