Machine data
2.3 Channel-specific machine data
Description: This MD is used to specify the machine axis which the channel axis/special
axis is assigned to. Each channel axis has to be assigned to a specific chan-
nel. A machine axis that has not been assigned to a channel is inactive, i.e.
the axis control is not computed, the axis is not shown on the screen, and it
cannot be programmed in any channel.
From software version 5, a machine axis need not be assigned to a channel
axis for reasons of uniform configuration. The MD for the machine axis is set
to 0 in this case. At the same time, MD11640 $MN_ENABLE_CHAN_AX_GAP must be
set to 1 (channel axis gaps are permitted).
From software version 5, the machine data MD20070 $MC_AXCONF_MACHAX_USED does
not directly refer to the machine axes created with MD10000
$MN_AXCONF_MACHAX_NAME_TAB, but to the logical machine axis map which is
defined with MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB.
MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB refers:
• directly to a local machine axis on the NCU,
• to a machine axis of another NCU in the NCU grouping or
• indirectly to an axis container with local or remote machine axes.
If the default values AX1, AX2, ..., AX31 are entered with MD10002
$MN_AXCONF_LOGIC_MACHAX_TAB, then the NCK behaves in the same way as up to
software version 4, this means that machine data MD20070
$MC_AXCONF_MACHAX_USED refers to the corresponding local machine axis.
Special cases:
• Each geometry axis must be assigned to a channel axis and a machine axis
so that it can be programmed.
• If a machine axis is assigned to several channels by means of MD20070
$MC_AXCONF_MACHAX_USED, then the number of the channel from which the
axis is to be programmed must be entered in MD30550
$MA_AXCONF_ASSIGN_MASTER_CHAN.
• Up to software version 4, the list of entries must not contain any gaps
(as from software version 5 - see above). In contrast, the assignment of
the machine axes used may contain gaps.
For example:
Permissible:
AXCONF_MACHAX_USED [0] = 3; 3rd MA is the 1st axis in the channel
AXCONF_MACHAX_USED [1] = 1; 1st MA is the 2nd axis in the channel
AXCONF_MACHAX_USED [2] = 5; 5th MA is the 3rd axis in the channel
AXCONF_MACHAX_USED [3] = 0
Error for software version 4, permissible for version 5:
AXCONF_MACHAX_USED [0] = 1; 1st MA is the 1st axis in the channel
AXCONF_MACHAX_USED [1] = 2; 2nd MA is the 2nd axis in the channel
AXCONF_MACHAX_USED [2] = 0; gap in the list ...
AXCONF_MACHAX_USED [3] = 3; ... of the channel axes
Axis identifiers must be defined in the corresponding list places of
