Machine data
2.3 Channel-specific machine data
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 associated with 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/spin-
dles, 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/spin-
dles, 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.
Bit 14 = 1:
The current setting of the basic frame is retained.
