TOOL_MANAGEMENT_TOOLHOLDER
Toolholder number

This MD only takes effect if tool management is active.
It is used to stipulate whether a tool holder number or spindle number have to be indicated
in order to define the location of the tool to be loaded. Tool management must know on
which tool holder the tool is to be loaded.
If the MD is larger than 0, the spindle numbers $TC_MPP5 are interpreted as tool holder
numbers.
The automatic address extension of T and of M06 is then the value of this MD
and no longer the value of MD 20090 SPIND_DEF_MASTER_SPIND.
For machines with several tool holders without a designated master spindle
the MD acts as a default value defining the tool holder to which the tool is to be loaded on
tool change. SETMTH(n) designates tool holder n as the master tool holder.
Tools which are to be loaded in a buffer location of the spindle type
and which have the value $TC_MPP5=n have the effect of correcting the tool path. Tools
with a value not equal to n have no effect on the offset.
Command SETMTH restores the tool holder stipulated in the MD as master tool holder.
When defining the magazine locations of internal magazines, spindle locations
–$TC_MPP1=2=2=spindle location– can be assigned a location type index ($TC_MPP5).
This assignes a concrete tool holder to the location.
