Machine data
2.3 Channel-specific machine data
If tool or magazine management is not active:
- No tool offset active after power-on. Active and programmed T depend on the
subsequent settings of the machine data (bits 0, 6).
If tool or magazine management is active:
-no significance.
Bit 2 = 1:
If tool or magazine management is not active:
- If bits 0 and 6 both = 1 (0x41), the tool offset of the last tool active in
the NCK is active after the first reset after power on.
(The value of the programmed tool depends on the value of machine data
MD20121 $MC_TOOL_PRESEL_RESET_VALUE.)
Notice: The NCK does not know the conditions at the machine.
For active tool or magazine management:
- Not relevant
Bit 3 = 0:
With and without active tool management:
- End of test mode: "Retain current setting for active tool length offset"
(bits 0 and 6 set) refers to the program which was active before activation
of test mode.
Bit 3 = 1:
Relevant only if tool management is not active:
- End of test mode: "Retain current setting for active tool length offset"
(bits 0 and 6 set) refers to the program which was active at the end of test
mode. (If tool management is active, the tool on the spindle is generally the
active tool. Exception only for MD20270 $MC_CUTTING_EDGE_DEFAULT = -2.)
Bit 4 = 0:Reserved
Bit 4 = 1:Reserved
Bit 5 = 0:Reserved
Bit 5 = 1:Reserved
Bit 6 = 0:
Initial setting for active tool length offset after reset/end of part program
acc. to MD20120 $MC_TOOL_RESET_VALUE, MD20130 $MC_CUTTING_EDGE_RESET_VALUE,
MD20123$MC_USEKT_RESET_VALUE and MD20132 $MC_SUMCORR_RESET_VALUE.
If MD22550 $MC_TOOL_CHANGE_MODE = 1, then in addition, the tool specified by
MD20121 $MC_TOOL_PRESEL_RESET_VALUE is preselected.
If tool or magazine management is active, MD20122 $MC_TOOL_RESET_NAME is used
instead of data MD20120 $MC_TOOL_RESET_VALUE.
Bit 6 = 1:
The current setting for active tool length offset is retained after reset/
end-of-part-program.
If tool or magazine management is active, the tool currently on the master
spindle (generally = master toolholder) is selected.
If the tool on the master spindle is disabled, the 'disabled' status is
ignored.
Please note that after a program ends or is canceled, either the most recent
value for master spindle or master toolholder programmed in the program or
the value specified with MD20090 $MC_SPIND_DEF_MASTER_SPIND or MD20124
$MC_TOOL_MANAGEMENT_TOOLHOLDER defines the master spindle or master tool-
holder.
(The selection is made using bit 16 or bit 17.)
For MD20270 $MC_CUTTING_EDGE_DEFAULT = -2, the following applies specifi-
cally:
