9.1.4 Origin Detection after Deceleration when DOG On (1: DOG/HOME (On))
This is the method using the DOG and origin signal and the action by homing command is as follows.
(1) Operation
(a) It accelerates to the setting homing direction and acts by homing high speed.
(b) In this case, if DOG signal is entered, it decelerates and acts by homing low speed.
(c) If encounters the origin signal as external input signal when the DOG is “On” while the homing low speed is
active, the origin shall be determined and it stops.
■ Operating Pattern
Note
1. Once the DOG signal is “On”, when the homing speed acts from high speed to low speed via
deceleration section, if the origin signal is entered in the state that the DOG signal is “ON”, the origin
will be determined promptly.
That is, when the homing speed decelerates, the origin will not be determined by the origin signal.
2. When encounters the external input high/low limit signal before origin after the DOG signal has
changed from “Off” to “On”, the action will be the same as the method of Article 9.1.3
3. If “On” time of origin signal is short, the positioning module can not recognize it.
