4.4.5 Axis Type Selection
There are two types of axis: An infinite length axis that resets the current value with a specified value, and a finite
length axis that does not reset the current value.
The finite length axis is used for rotation in one direction only, where the current value data does not need to be reset
after rotation, and for return and other operations are performed only within a specified range.
The infinite length axis is used for applications such as resetting the current value data for a conveyor belt or other
device to 0 after one rotation.
The type of the axis to be used is selected by fixed parameter No. 07 (Axis Selection).
If infinite length axis is set, the current counter value after conversion and the PI latch data after conversion is stored in
the range 0 to infinite length axis reset position
− 1.
Set the reset position in the counter fixed parameter No. 13 (Maximum Value of Rotary Counter) (Infinite Length Axis
Reset Position) (POSMAX).
