How to Execute an Absolute Reset on a Controller of Version J* or Earlier

[1] Connect the motor and encoder/brake cables to the controller.
[2] Connect the host PLC to the PIO connector using the supplied flat cable.
[3] If two or more axes are connected, set the address using SW1 on the controller. For details, refer to 2.2,

“Names and Functions of Parts” and 3.2, "Names and Functions of Parts"

[4] Move the actuator slider or rod to a position where it is in contact with the mechanical end on the home

side.

[5] Turn switch No. 1 (bottom switch) of the controller’s SW2 to ON (tilt to the right).
[6] Turn on the main controller power.
[7] Connect the battery to the controller.
[8] The RDY LED will illuminate.
[9] Turn switch No. 1 of the controller’s SW2 to OFF (tilt to the left). Note 1)

An absolute reset has been executed. The home has been set several millimeters ahead of the current
position (mechanical end) (the specific distance from the mechanical end will vary depending on the
actuator model).

[10] To operate the actuator right away, turn ON the PIO pause/servo ON inputs.

Note 1) If switch No. 1 of SW2 remains ON, the next time the power is turned on an absolute reset will be

executed based on the actuator position at that time.

Note 1) The absolute RCS controller can be used only with absolute RCS actuators. It cannot be used

with standard RCS actuators.
