10.3 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.
10.3.1 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
10.3.2 Detailed Descriptions on Parameter Settings for Finite Length Axes on
page 10-8. Set these parameters carefully. If they are not set correctly, the cur-
rent position may not be correct after the power is turned ON. Machine damage
may occur.
