Synchronization Command (P Code)
[Function]
In simultaneous 4-axis operation, although two turrets can be operated independently, there are
operations that require synchronized control of two turrets; spindle rotation during cutting using tools
in both turrets is an example that requires such control.
To synchronize the execution timing of the G13 side program and the G14 side program, a special
command is provided. This synchronization command is specified using address character P.
[Programming format]
P__ __ __ __
P: Integer (up to four digits)
P codes control the execution order of the G13 side and G14 side programs.
[Details]
•
Program execution proceeds in order from smaller to larger P code numbers.
•
If a P code is read during the execution of a program, execution of that program is suspended
until a P code is read in the other side program. When a P code appears in the other side
program, the P code numbers are compared and the program with the smaller P code number
is executed. If the P code numbers are the same, both programs are executed. When
execution of the program for one turret is completed during suspension of the program for the
other turret, execution of the suspended program is resumed.
[Program example]
Spindle rotation commands, spindle speed commands, and gear range selection commands that
must be synchronized between the programs of the two turrets should be specified in the manner as
indicated below.

In the example program above, block A is executed for both G13 and G14 side programs. Blocks B,
C and D are executed in this order.
