Axis No. to which speed change request will be
(S1)

(1) A speed change is made shown below.
(a) The speed change accepting flag (M2061 to M2092) corresponding 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 change accepting flag is turned OFF.
(2) The axis No. that may be set at (S1) is within the following range.
Q173DSCPU
1 to 32
(3) For interpolation control, set any one of the interpolation axes to (S1). When linear
interpolation control is exercised, a speed change varies as described below with
the positioning speed designation method set in the servo program.
