(4) Superimposed Control
The superimposed control function adds the amount of movement of an axis (superimposed control
master axis) to an axis (superimposed control slave axis) for which ordinary move commands are
being executed. This function is similar to synchronous control but differs from it in that move
commands can be issued not only for the master axis but also for the slave axis. The slave axis
moves by the sum of the amount of movement specified by move commands and the amount of
movement commands for the master axis. Appropriate setting of parameter OMRx (bit3 of
parameter No.8162) can reverse the direction in which the master and slave axes move. The
superimposed control for 3-path control can only add the amount of movement of an axis in path 1
to that of an axis in path 2 and add that to the amount of movement of an axis in path 3. It is
impossible to superimpose except this pattern in the superimposed control for 3-path control.
(a) Setting
Parameter No.8186 specifies between which axes move commands are to be superimposed.
(Example)
To superimposed the amount of movement of the Z1-axis to that of the Z2-axis:
Parameter No.8186z of path 2 = 12
To superimposed the amount of movement of the Z2-axis to that of the Z3-axis:
Parameter No.8186z of path 3 = 22
(b) Programming
Use M codes for wait, beginning, and terminating superimposed control in a machining
program in the stated order. It is also possible to begin and terminate composite control
without using M codes.
(c) 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).
