1. AXIS CONTROL
184
NOTE
1 If more than one slave axis is synchronized with one master
axis, the master axis is set with the workpiece coordinate
system that corresponds to the current position of the first
slave axis that is synchronized with the master axis.
2 The tool offset is taken into account when the coordinate
system is set up. So, the coordinate system is set up
normally even when tool geometry compensation is
applied.
Move commands can be interchanged between an axis in one path and an
axis in the other path. In other words, when a machining program is
executed for one path, actual machining can be performed with an axis in
the other path. Coordinate systems can also be switched automatically
between independent control and composite control.
Parameter No. 8183 of path 2 specifies the axes between which
commands are to be interchanged.
(Example) Between the X1– and X2–axes:
Parameter No. 8183x of path 2 = 1
Between the Y1– and X2–axes:
Parameter No. 8183x of path 2 = 4
Between The X1– and Y2–axes:
Parameter No. 8183y of path 2 = 1
To set up coordinate systems automatically when composite control
begins or ends, set parameters MPMx and MPSx (bits 4 and 5 of
parameter No. 8162) to ”1”, and specify the positional relationship
between the coordinate systems in parameter No. 8184.
Use M codes for wait, beginning, and terminating composite control in
a machining program in the stated order. It is also possible to begin and
terminate composite control without using M codes.
When composite control begins or ends (when an M code is issued), the
composite control axis selection signals MIX1 to MIX7 for the target axis
in path 1 (from the PMC to the CNC) are changed from “0” to “1” (to
begin composite control) or from “1” to “0” (to end composite control).
