 The zeroPointOffsAxis list located in CfgRearSideTrafo contains the key 
names of the axes with datum shift. The transformations for the datum shift 
of the axes entered here are listed in the zeroPointOffset list. The 
transformation for the datum shift is assigned to the axis through the list 
index. The transformation for the datum shift of the Z1 axis is named 
Trans_Z1 and is contained in the zeroPointOffset list.
 The kinematics group for rear-side machining with the opposing spindle S4 
is activated with the G function G30 Q4. When the program is canceled or 
finished, the currently active kinematics for rear-side-machining remains 
active at first and is only deactivated when a new program is selected in 
Program Run or when the control is restarted.
