Returning to Origin Position movements
When the Card Motor is commanded to return to Origin, the Card Motor starts moving from the
position where it was in the direction set in the controller setting software in the [Basic Parameter
Setup] page under [Method to Return to Origin]. Refer to ”(1)” in the figure below.
The Card Motor moves to the respective stroke end until it is stopped by the mechanical end stop and
waits there for a specific time, until the controller has recognized the position as the mechanical end
stop. Then, the Card Motor moves in the opposite direction at low speed, stops at a pre-defined
distance and sets that position as the Origin Position. Refer to ”(2)” in the figure below.

Return to Origin Position reference example
∗
The controller uses the "Load Mass" value set in "Step Data No. 1" for the "Return to Origin"
operation.
Therefore confirm that the "Load Mass" value for "Step Data No. 1" is appropriate for the "Return to
Origin" operation.
Caution
The movement direction of the [Return to Origin Position] operation varies depending on the used
[Return to Origin Position] method.
The Origin position varies depending on the used [Return to Origin Position] method.
Set the operation conditions according to the requirements of the actual equipment in your
application.
With the LAT3F series it is possible to return to the sensor Origin. The sensor Origin position varies
depending on the stroke.
If the return to Origin position is performed using an external jig or workpiece to stop the table, the
Origin position may be set outside of the travel range. Do not set the target position of the step data
outside of the Card Motor movable range. It may damage the workpieces and the Card Motor.
