Fanuc Alarm PS992 SPL : ERROR

Fanuc Alarm Description
Fanuc 15i
Movement was specified for an axis other than those used for spline interpolation.
This alarm is also generated, for example, when movement is specified along the Z–axis when spline interpolation along the 2 axes, X and Y, is executed in the 3–dimensional tool offset mode in which the 3 axes, X, Y and Z, are set as the offset vector components.
