Both before and after the M codes for a start and a cancellation of
superimposed control, specify a waiting M code.

- Signal operation
When superimposed control begins or ends (when an M code is
issued), the superimposed control axis selection signals OVLS1 to
OVLS8 for the target slave axis (from the PMC to the CNC) are
changed from "0" to "1" (to begin superimposed control) or from "1"
to "0" (to terminate superimposed control).
- Examples of applications
Suppose that a workpiece on the spindle (Z1-axis) that moves along
the axis is to be cut with a tool in path 1 and a tool in path 2
simultaneously. This example superimposes the amount of movement
of the Z1-axis (master) on that of the Z2-axis (slave).
