Item Air cylinder This controller
Position check
upon power on
Determined using a reed
switch or other external
detection sensor.
Immediately after the power has been turned on, the current
position is indeterminable because no mechanical
coordinates are stored in the controller.
After the power is turned on, therefore, a home return
command must always be issued to establish coordinates.
[1] The actuator moves toward the mechanical end on the
motor side at the home return speed.
[2] The actuator contacts the mechanical end and reverses its
direction, moves to the home position, and then pauses.
(Note) Make sure no obstacles are present in the home return
path.
