Machine data
3.3 Channel-specific machine data
Please note that after a program ends or is terminated, either the most recent value
for master spindle or master toolholder programmed in the program, or the value set in
MD20090 $MC_SPIND_DEF_MASTER_SPIND or MD20124 $MC_TOOL_MANAGEMENT_TOOLHOLDER defines
the master spindle or master toolholder.
(The selection is made in bit 16 or bit 17.)
For MD20270 $MC_CUTTING_EDGE_DEFAULT = -2, the following applies specifically:
If a tool has been loaded into the spindle, but a new offset D has not yet been
programmed, the previous tool is still active in the NCK.
If machining is canceled in this status (e.g. with the Reset key), the offset is
defined with the smallest D number of the master spindle tool.
Bit 7 = 0:
Initial setting for active transformation after reset/end of part program according to
MD20140 $MC_TRAFO_RESET_VALUE.
Bit 7 = 1:
The current setting for active transformation is retained after reset/end of part
program.
Bit 8 = 0:
Coupled-motion axis groups are ungrouped at reset/end of part program.
Bit 8 = 1:
Coupled-motion axis groups remain active after reset/end of part program.
Bit 9 = 0:
Tangential correction is deactivated at reset/end of part program.
Bit 9 = 1:
Tangential correction remains active after reset/end of part program.
Bit 10 = 0:
Non-configured synchronous spindle coupling is deactivated at reset/end of part
program.
Bit 10 = 1:
Non-configured synchronous spindle coupling remains active after reset/end of part
program.
Bit 11 = 0:
At reset/end of part program, the setting data SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE
is reset to 0 for all non-active axes/spindles, i.e. traversing at revolutional
feedrate is canceled and the setting for path and synchronous axes is reset to the
master spindle (default).
Bit 11 = 1:
The current setting for revolutional feedrate is retained after reset/end of part
program. At the start of the part program, the setting data SD43300
$SA_ASSIGN_FEED_PER_REV_SOURCE is reset to 0 for all non-active axes/spindles, i.e.
traversing at revolutional feedrate is canceled and the setting for path and
synchronous axes is reset to the master spindle (default).
Bit 12 = 0:
If machine data MD20118 $MC_GEOAX_CHANGE_RESET is set, a changed geometry axis
assignment is canceled at reset/end of part program. The initial setting for the
geometry axis assignment defined in the machine data becomes active.
Bit 12 = 1:
A changed geometry axis assignment remains active after reset/end of part program.
Bit 13 = 0:
Master value couplings are canceled at reset/end of part program.
Bit 13 = 1:
Master value couplings remain active after reset/end of part program.
Bit 14 = 0:
The basic frame is deselected.
