18.6 Toolholder with orientation capability
Basic Functions
1522 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Automatic toolholder selection, RESET
For RESET or at program start, a toolholder can be selected automatically via the machine data:
MD20126 $MC_TOOL_CARRIER_RESET_VALUE (Active toolholder at RESET)
It is handled similar to the controlled selection of a tool via the machine data:
MD20120 $MC_TOOL_RESET_VALUE (Tool length compensation Power up (RESET/TP-End))
The behavior at RESET or at program start is controlled as in the case of tool selection via the same bit 6 in the
machine data:
MD20110 $MC_RESET_MODE_MASK (definition of initial control settings after RESET/TP-End)
Or:
MD20112 $MC_START_MODE_MASK (definition of initial control system settings at NC-START)

SW 6.3 and higher
If TCOABS was active for the last selection before reset, the behavior is unchanged compared to previous
versions. A different active G code causes the toolholder with orientation capability to be activated with the frame
that was active before the last reset. Modified toolholder data ($TC_CARR...) are also considered. If these data
are unchanged, the toolholder is activated in exactly the same state as before reset. If the toolholder data were
changed after the toolholder selection before reset, selection corresponding to the last frame is not always
possible. In this case, the toolholder with orientation capability is selected according to the G-Code (group 42)
values valid at this time and the active frame.
MD22530 output of auxiliary functions to PLC
That, optionally, a constant or an M code is output when the toolholder is selected, whose number of the code is
derived from the toolholder number. Can be set with the machine data:
MD22530 $MC_TOCARR_CHANGE_M_CODE (M-Code at toolholder change)
