will be generated per revolution of servo motor with 13-bit incremental encoder.
Command unit= 0.001mm (the screw moves 0.001mm per pulse generated by the system)
Amount of movement per revolution of bearing axle= 6mm/0.001mm=6000

Fig. 5-9 Servo motor and screw sharing same axle (without reduction gearbox)
Servo motor and screw are sharing the same axle (without reduction gearbox), and one revolution
of motor will lead to one rotation of screw.
