Commanding spindle feedforward control (G135/G136/G137)

Release Note

The availability of this function depends on the configuration and on the version scope.

These commands permit the spindle-specific programming of feedforward control. The commands may not be used simultaneously with other spindle-specific commands.

Activation is programmed with G135.

Spindle-specific, percentage weighting of the calculated feedforward control variables takes place with G136. It is limited to 100%.

G137 deactivates feedforward control. It is also possible to specify the selection and weighting of the feedforward control in the same block.

If feedforward control is disabled or enabled during the NC program, the weighting factors remain at the values set by G136 or, if no G136 is programmed, to 100%.
