Address extension for NC addresses T and M
MD20096
Whether the address extension of T and M is also to be interpreted as spindle number when the
tool management is not activated, can be set via the machine data:
MD20096 $MC_T_M_ADDRESS_EXT_IS_SPINO (spindle number as address extension)
The same rules then apply to the relationship between the D number and T number as when
the "Tool management" function is active.
Effect on the D number
An offset data set is determined by the D number.
The D address cannot be programmed with an address extension.
The evaluation of the D address always refers to the currently active tool.
The programmed D address refers to the active tool in relation to the master spindle (same as
for tool management function), when machine data is set:
MD20096 $MC_T_M_ADDRESS_EXT_IS_SPINO = TRUE (spindle number as address
extension).
Effect on the T number
If the "Tool management" function is active, the values programmed with reference to the
master spindle (or master toolholder) are displayed as programmed/active T numbers.
If tool management is not active, all programmed T values are displayed as programmed/
active, regardless of the programmed address extension.
Only the T value programmed in relation to the master spindle is shown as programmed/active,
when:
MD20096 $MC_T_M_ADDRESS_EXT_IS_SPINO = TRUE (spindle number as address
extension).
Example
The following example below shows the effect of MD20096.
