This setting is used to select either an finite or infinite length axis.
Set to 0 when using the axis as a finite length axis.
For an axis performing absolute position detection, set the parameters as shown in the following
table.

■ If using the SVB-01 Module or the built-in SVB Module
Refer to the following table and set the fixed parameter 36 (Encoder Resolution in Pulses/Resolution)
according to the number of servomotor bits. The settings can be used for all SERVOPACK models.
