5.1.3 Axis Type Selection
There are two types of position control: Finite length position control for return and other operations that are per-
formed only within a specified range, and infinite length position control, which is used for moving in one direction
only. Infinite length position control can reset the position to 0 after one rotation, e.g., belt conveyors, or move in one
direction only, without resetting position after one rotation. The axis type selection sets which of these types of position
control is to be used.
The details of the Axis Type Selection are listed in the following table.

Flag 1, Axis Selec-
tion
Specify the position control method for the controlled
axis.
0: Finite Length Axis
Set a finite length axis if control is performed within a
limited length or for an axis that uses infinite length
control in one moving direction only without resetting
the position every rotation.
When an absolute encoder is used with the infinite
position control method for motion in one direction,
set the reference unit to pulse.
If it is set to anything other than pulse, position error
may occur.
1: Infinite Length Axis
Set an infinite length axis for an axis that uses infinite
length control while resetting the position every rota-
tion.

Infinite Length
Axis Reset Posi-
tion (POSMAX) Set the reset position of the position data when an infi-
nite length axis has been set for the axis type using the
reference unit.
