1. AXIS CONTROL
194
MCDx The axes to be replaced with each other under composite control have the
coordinate systems placed:
0 : In the same direction. Simple composite control is applied. (The axes
of paths 1 and 2 move in the same direction.)
1 : In opposite directions. Mirror–image composite control is applied.
(The axes of paths 1 and 2 move in opposite directions.)
This parameter determines the direction in which an axis moves. The
parameter is also used to automatically set the coordinate system when
composite control is started or terminated.
[Example]
MCDx and MCDz are set in accordance with the relationship among the
X– and Y–axes of tool posts 1 and 2, as indicated in the figure below.

MUMx In mixed control, a move command for the axis:
0 : Can be specified.
1 : Cannot be specified.
NOTE
Upon the execution of a move command along an axis for
which MUMx is set to 1 during mixed control, alarm P/S 226
is issued. If the X1–axis and X2–axis are under mixed
control, for example, a command for the X2–axis (X1–axis
motor) is disabled by setting the MUMx parameter for tool
post No. 2 to 1.
