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.
(1) The position control movement amount can be changed during the speed
control section of speed-position switching control (INC mode).
A movement amount change request will be ignored unless issued during the
speed control section of the speed-position switching control (INC mode).
(2) The "new movement amount" is stored in "[Cd.23] Speed-position switching
control movement amount change register" by the sequence program during
speed control.
When the speed-position switching signal is turned ON, the movement amount
for position control is stored in "[Cd.23] Speed-position switching control
movement amount change register".
(3) The movement amount is stored in the "[Md.29] Speed-position switching
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.
