For instance: (an example of YASKAWA servo) screw pitch of a certain type of machine is 5mm,
with 17 bit encoder resolution, ―0.0001mm/p‖ pulse equivalent and ―1:1‖ deceleration ratio.

 Rotary Axis
The pulse equivalent of rotary axis refers to the rotation degree of the axis clamping the workpiece
corresponding to each pulse. The difference of rotary axis movement from linear axis movement lies in
that the screw pitch of rotary axis is 360 degrees. Therefore, in calculating rotary axis pulse equivalent,
you just need to replace screw pitch with 360.

Note:
The setting value of pulse equivalent must be matching with that of the electronic gear ratio of servo driver or that of
subdivision of stepping driver.
3.2.3 Upper & Lower Limit Setting of Workbench Stroke
Workbench stroke refers to the valid machining stroke range of machine tool on X / Y / Z / A axis and
the system will carry out software limit in terms of this range in order to protect the machine.
