(1) A speed change is made in the following procedure.
(a) The speed changing flag (M2061 to M2092) correspond to the axis specified
with (S1) is turned ON.
(b) The speed of the axis specified with (S1) is changed to the speed specified
with (S2).
(c) The speed changing flag is turned OFF.
(2) The axis No. that may be set at (S1) is within the following range.
