6 POSITIONING CONTROL
6.16 Speed-Switching Control
(1) Positioning control performs changing the speed on the point beforehand set by
one start.
(2) The speed-switching points and speed are set using the servo program.
(3) Repetition control between any speed-switching points can be performed by using
repetition instructions.
(4) M-codes and torque limit values can be changed at each speed-switching point.
