x: Signal status is optional since override values are not effective for SG1 and SG3
Configuring NCK-SGE
NCK-SGEs (override selection bits 3, 2, 1, 0) are configured using the following machine data:
for 840D sl:
MD36978 $MA_SAFE_OVR_INPUT[n] (input assignment for override selection)
Defining SG override factors
The following machine data are used to define the SG override factors themselves (percentage
values):
for 840D sl:
MD36932 $MA_SAFE_VELO_OVR_FACTOR[n]
for SINAMICS S120:
p9532[n] SI Motion SLS (SG) override factor (Control Unit)
