Create the positioning operation program.
A positioning operation program and a parameter setting program should provide an interlock
in the program not to execute simultaneously.
In this program example, while the parameter setting program is executing, M380, M385 or M390 is ON.

Initializing the positioning parameters and servo parameters in the buffer memory (X-axis and
Y-axis).
Initialization is not required in the following case.
In this case, this circuit block is unnecessary. And change the contact of T12 to M391.
Enables control commands
in unit No. 1.
Turns ON the initialization
command for each
parameter in unit No. 1.

When T12 turns ON,
initialization of each
parameter stored in the
buffer memory in unit No. 1
is completed.
It takes 20 ms or more for
initialization of parameters.
