Machine setup chart
1. Pulse Equiv(Pulse Equivalent)
The number of pulses of the system needs to send when machine moves every
1mm.Unit：pulse/mm.
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:
