4.3.7 Position-speed switching control
1-axis control with forward run position/speed switching and reverse run position/speed switching (increment system).
(1) The position control is carried out after the start, and switched to the speed control
before reaching to the positioning end point by the external command signal
(select the "speed-position/position-speed switching request" for the "external
command function selection") when the "speed-position switching enable flag" is
ON (Enable), and then the speed control is carried out until the input of the stop
signal.
(2) The current feed value at the start and during speed control depends on the
setting of "current feed value during speed control". (The machine feed value is
always incremented.)
