10.4.2 Parameters Setting for Simple Absolute Infinite Length Position Control
Set the following parameters to use the Simple Absolute Infinite Length Position Control for an infinite length axis.
( 1 ) Parameter Settings for Simple Absolute Infinite Length Position Control
Set the fixed parameters No.1 bit 0 and bit 9, and No. 30 as follows to set the Simple Absolute Infinite Length Position
Control for an infinite length axis.
( 2 ) Machine Controller Fixed Parameters for Absolute Position Detection
The parameters for which precautions are provided must be set referring to
10.4.3 Detailed Descriptions on Parameter Settings for Simple Absolute Infinite
Length Axes on page 10-18. 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. CAUTION
