Spindle specific feedforward control (G135, G136, G137)

Spindle specific feedforward control (G135, G136, G137) 1:

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

This command allows the spindle specific programming of feedforward control. The commands may not be used simultaneously together with other spindle-specific commands.

The activation is programmed with G135. Spindle-specific, percentage weighting of the calculated feedforward control variables is done with G136. It is limited to 100%. G137 deactivates the feedforward control. It is also possible to enter the selection and weighting of the feedforward control into the same command sequence.

If the feedforward control is switched on or off during the NC-program, the weighting factors remain on the values set through G136, or if no G136 is programmed on 100%.

Programming example

S[G135] Activation of feedforward control for S 
S[G136=80] Definition of weighting in percent 
S[G137] Deactivation of feedforward control 
S2[G135 G136=90] Activation and weighting 90% for S2 
S2[G136=0] Change of weighting on 0% 
S1[G135] Activation and default weighting 100% for S1
