Example)
1: 1: 2
When the spindle motor, spindle, and position coder are
connected as shown left, let the variables be as follows:
S = 3600
G = 3000
L = 360_
(One spindle rotation per spindle motor rotaion)
= La / 4096
= 720_/4096
= 0.17578_
La= 720_
(One position coder rotation requires two spindle
rotations =360_ 2)
4096=Detection pulse per positioncoder rotation

NOTE
The detection unit is a=La/2048 when the position coder
built–in spindle motor uses a position coder of 512 pulses
per revolution.

Positional deviation limit imposed while the tapping axis is stopped in rigid tapping
[Data type] Word
[Unit of data] Detection unit
[Valid data range] 1 to 32767
This parameter sets the limit value of a tapping axis positioning deviation
during stop in rigid tapping.
