position. Perform it several times to make sure it returns to the same position.
(Perform an absolute reset for the absolute type.)
(3) Check the amount of position difference.
It is possible that the position is slightly different from that before the replacement.
Therefore, it is required that the amount of difference is measured by positioning at a position No.

(4) The amount of difference needs to be included to the home preset value for XSEL and SSEL
controllers and to the home-return offset value for SCON controller.
[Refer to "11.2 Setting for Home Preset Value and Home-Return Offset Value" for the method of
setting.]
* If the position differs in a large amount (more than 1 turn of the ball screw = more than 1 lead length),
or if the home-return is not constant when the operation is repeated, repeat the process of motor unit
attachment again following this Instruction Manual.
Please make sure that the correct size of spacer has been chosen. The correct size can be found as
