Changing the position control movement amount
In "speed-position switching control (INC mode)", the position control movement
amount can be changed during the speed control section.

control section of speed-position switching control (INC mode).
A movement amount change request will be ignored unless issued during the

for position control is stored in "

control positioning amount" of the axis monitor area from the point where the
control changes to position control by the input of a speed-position switching
signal from an external device.
