4-2 Origin Search Procedure
4-21
ORIGIN SEARCH OPERATION Mode
Operation at Forward Direction Limit Input and Operation at Reverse Direction Limit Input
Origin Search Start Direction
Origin Input Detecting Direction
Select one of 15 operations to determine the mechanical origin. For operation details, refer to
"Origin Confirmation Operation" on page 4-23.
Select whether to reverse the axis and continue with the Origin Search, or not reverse the axis
but generate an error and stop the axis, when the axis reaches the limit input in the operating
direction during Origin Search. To reverse the axis, also select the stopping method.
When you set [Reverse] for limit input operation in both directions, the axis generates an error
and stops if the axis could not detect the origin after moving from the limit input position opposite
to the origin input detection direction to the other limit input position.
Select the direction in which the axis starts moving when Origin Search starts. Refer to the figure below.
Select the direction of confirming the origin. Refer to the figure below.
When the origin search start direction is the same as the origin input detecting direction
When the origin search start direction is different from the origin input detecting direction
