9.1.5 Origin Detection by DOG (2: DOG)
This is used when determines the origin only by using the DOG.
(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 transferred to opposite direction acts by homing
high speed.
(c) When it operates in opposite direction, if DOG is entered, it decelerates and transferred to opposite direction
and acts by homing low speed.
(d) In this case, if encounters DOG origin signal, the origin would be determined and it stops.
■ Operating Pattern
Note
If “ON” time of DOG is longer than deceleration time, the action is as follows.
