Selecting K Factors With M105/M106 - HEIDENHAIN TNC 415 Technical Manual

7.5 Selecting K
v
A second set of Kv factors is selected with M-function M105. These Kv factors are defined in
machine parameters MP1515.x (feed precontrol) and MP1815.x (lag mode). Selecting a higher Kv
factor can selectively enhance the contour accuracy. M105 influences the compensation of reversal
spikes during circular movement. M105 activates the machine parameters MP715 and MP716. The
original set of K factors is restored by the M-function M106. M-functions M105/M106 are enabled
