Formula = pulses per revolution / distance per revolution
Pulses per revolution formula: (360 °/stepper angle)* Driver subdivision
Some stepper drivers mark pulse number directly.
Distance/r formula：
Screw drive machine = screw pitch * mechanical transmission ratio
Rack drive machine = rack module * gear teeth number*π* mechanical
transmission ratio
So stepper motor system formula:
Screw drive：
Formula Description: step angle is the angle of the motor parameters, motor rotation
step walk.
Driver subdivison is the parameter set by the driver.
Screw pitch(above picture): The distance that the nut moves when the ball screw
makes one rotation.
Transmission ratio: The speed ratio or angular velocity ratio of the capstan and
the driven wheel.
Rack drive：
