8.5.2 Composite Control
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.
Explanation
- Setting
Specify which axis is to interchange with which axis, with parameter
No. 8183, using the path numbers and the axis numbers.
Example)
For an axis configuration in which all paths consist of X, Z, and
Y axes
Between the Z1- and Z4-axes:
Parameter No. 8183z of path 4 = 102
Between the X5- and X8-axes:
Parameter No. 8183x of path 8 = 501
Between the X1- and Y2-axes:
Parameter No. 8183y of path 2 = 101
To set up coordinate systems automatically when composite control
begins or ends, set parameters MPMx and MPSx (No. 8162 #4 and
#5) to "1", and specify the positional relationship between the
coordinate systems in parameter No. 8184.
- Programming
Both before and after the M codes for a start and a cancellation of
composite control, specify a waiting M code.

- Signal operation
When you want to start or cancel composite control (when you specify
an M code, for example), change the composite control axis select
signal between MIX1 and MIX8 for the axis subject to composite
control that is specified with parameter No. 8183 (the signal being
sent from the PMC to the CNC) from "0" to "1" (to start composite
control) and from "1" to "0" (to cancel composite control).
