(D1+0) : Device which make turn on for one scan at accept completion of
instruction.
(D1+1) : Device which make turn on for one scan at accept abnormal completion
of instruction.
("D1+0" also turns on at the abnormal completion.)

(Note-1): Omission possible with both of (D1) and (D2) omission.
(Note-2): "n" shows the numerical value correspond to axis No. (n=1 to 32)
[Controls]
(1) The speed of command generation axis specified with (S1) is changed to the
speed specified with (n2) during positioning or JOG operating.
(2) There is not an interlock signal on the shared memory during speed change.
When the multiple instructions are executed toward the same axis of same Motion
CPU, the speed is changed to specified value by last instruction.
