Calculate the number of pulses (AP) and travel distance (AL) of the linear encoder per ball screw
revolution in the following conditions.
Ball screw lead: 20 mm
Linear encoder resolution: 0.05 μm
Number of linear encoder pulses (AP) per ball screw revolution
= Ball screw lead/linear encoder resolution= 20 mm/0.05 μm = 400000 pulses
