Chapter 7 Usage of Various Functions
Origin Detection after Deceleration when Approximate origin turns on
(3)
This is the method using the approximate origin and origin signal and the action by origin return command is as follows.
(A) It accelerates to the setting origin return direction and acts by origin return high speed.
(B) In this case, if approximate origin as external input is entered, it decelerates and acts by origin return low speed.
(C) If encounters the origin signal as external input signal while the origin return low speed is active, the origin shall be
determined and it stops.
