9.1.6 Origin Detection by Origin and Upper/Lower Limit (3: Upper/Lower Limit/Home)
This is the homing method using external input upper/lower signal and origin signal and is used in case of not
using the DOG signal.
(1) Operation
(a) It accelerates to the setting homing direction and acts by homing high speed.
(b) In this case, if High/Low signal is entered, it transferred to opposite direction and acts by homing low speed.
(c) If encounters the origin signals while the homing low speed is active, the origin would be determined and it
stops.
■ Operating Pattern
Note
In case that origin signal is “ON” before entering the external input high/low limit signal, it carries
out the homing low speed operation when the external input high/low limit signal is entered and
when origin signal is “ON”, the origin will be determined.
