(2) Origin detection after DOG Off
The operations by Home Return instruction using DOG and origin signal are as follows.
(a) If home return command (ORG instruction) is executed, it accelerates toward a preset home
return direction and with Home high speed.
(b) During operating with Home Return High speed, if rising edge of DOG signal occurs, it
operates with Home Return Low speed and monitors if there is falling edge of DOG signal. At
this time, though Origin signal is inputted while DOG signal is On, Origin is not determined.
(c) If first origin signal is entered after DOG signal changes from “On” to “Off”, it stops.
Remark
• While DOG signal is “On”, origin is not determined by origin signal. That is, origin may be
determined as soon as origin signal is inputted after DOG signal changes from “On” to “Off”.
