Machine data
Only one section is specified, which extends beyond the necessary geometry/channel
configuration and machine axis parameters.
$MN_NUM_EG = 5
$MN_MM_NUM_CURVE_TABS = 5
$MN_MM_NUM_CURVE_SEGMENTS = 50
$MN_MM_NUM_CURVE_POLYNOMS = 100
Setting data
If the scaling described in Chapter "Electronic Gearbox (EG)" is used, the following applies,
as in the case of an offset:
MD43108 $SD_LEAD_SCALE_OUT_POS[4] = 1.2 ; scaling for table C4
System variables
In accordance with the above definitions, the following values are entered in the associated
system variables by the control. Options of access to these system variables are described in
SW 7.1 and higher:
