Follow the above procedure in the following cases:
• When starting up the absolute position detection system for the first time
• When the servomotor was replaced
• When alarm related to the absolute encoder occurred

If the parameters [P5AA04], [P5AA05], and [P5AA06] are changed after ABS
origin setting, the alarm [300Dh: ABS encoder error] may occur when the
power is turned ON.

Remark
Only the MLK slaves can be used as the
absolute value detection system.
Sets the offset amount for the ABS origin
setting.
The present position after ABS origin set-
ting execution will be the value set in this
parameter.
Coordinate system management:
Limited length axis and Unlimited length
axis are treated differently.
