Tool Length Compensation 
Any active tool length compensation remains operative and is applied to the new geometry 
axes after replacement. 
The system treats tool length compensations as not yet applied for the following geometry 
axes: 
•  All geometry axes, which have been newly added to the geometry axis grouping. 
•  All geometry axes, which have changed their positioning within the geometry axis 
grouping. 
Geometry axes, which retain their position within the geometry axis grouping after a 
replacement operation, also retain their status with respect to tool length compensation. 
RESET 
MD20110 RESET_MODE_MASK 
 
Bit 12:   Reset response of the modified geometry axis assignment. 
Bit 12 = 0  When machine data $MC_GEOAX_CHANGE_RESET is enabled, a modified 
geometry axis assignment is cleared on Reset or end of part program. The basic 
setting defined in the machine data for the geometry axis assignment is activated. 
Bit 12 = 1  A modified geometry axis assignment remains active after a reset/part-program end.
MD20118 GEOAX_CHANGE_RESET 
 
FALSE:  The current configuration of the geometry axes remains unchanged on reset and 
program start. With this setting, the response is identical to older software versions 
without geometry axis replacement. 
TRUE:  The configuration of the geometry axes remains unchanged or is switched to the 
basic state defined in machine data AXCONF_GEOAX_ASSIGN_TAB on Reset and 
part-program end (according to machine data $MC_RESET_MODE_MASK) and on 
part-program start (according to machine data$MC_START_MODE_MASK). 
Program start 
Analogously to the Reset response, the response on Start is determined by: 
MD20112 START_MODE_MASK 
 
Bit 12:   Response of the modified geometry axis assignment. 
Bit 12 = 0  A modified geometry axis assignment remains active on part-program start. 
Bit 12 = 1  A modified geometry axis assignment is cleared on part-program start.
