Definition
The step size sets the amount of rotation per input step.
Fifteen step sizes are available using Jumper J6 position 3-4
and DIP switch S1 positions 1-3 as shown. For all Pacific
Scientific stepper motors and all 1.8
°
step motors, step size can
be converted to steps per rotation using the following table:
