8. Return to origin
8.1 Return to origin
After inputting the set data, it is necessary to perform a return to origin (to establish the origin point)
before starting the positioning or pushing operation. (To ensure the position of origin)
●Return to origin operation
The electric actuator moves in the return to origin direction (this direction is dependent on the electric
actuator) from the initial position at the moment of power-on: See (1) in the diagram below.
When the electric actuator reaches the end of travel limit it pauses for a short time. The controller
recognizes the position as the end of travel limit of the electric actuator. Then, the electric actuator
moves at a low speed in the direction opposite to the return to origin direction: See (2) in the diagram
below.

8.2 Positioning operation
Step data “Pushing force” is 0.
The electric actuator moves to the target position specified by the step data “Position.”
