9.3 Absolute Position Detection for Finite Length Axes
This section describes the procedure for setting parameters and precautions on setting zero-point and turning ON the
power supply when using the axis as a finite length axis.
9.3.1 Parameter Settings for Finite Length Axes
The following parameters must be set to enable the absolute position detection function when using an axis as a finite
length axis.
( 1 ) Machine Controller Fixed Parameters for Absolute Position Detection
 The parameters for which precautions are provided must be set referring to 9.3.1 ( 3 ) Detailed
Descriptions. Set these parameters carefully. If they are not set correctly, the current position may not be
correct after the power is turned ON. Machine damage may occur.
