Timer (us)
Full-step angle (deg)
Full-step 1.8 deg => 200 pulses/rev
Microstep (sub-steps)
Reduction ratio
1 = direct
Pulse frequency (Hz)
Screw lead (mm)
for mechanical speed
Gear pitch diameter (mm, optional)
Calculate
Reset
Result
Full-step 1.8 deg => 200 pulses/rev; microstep divides it.
Timer setting value (us)
Timer base (us)
e.g. 1 us per count
Full-step angle (deg)
Microstep (sub-steps)
Calculate
Reset
Result
freq = 1e6 / (timer_value * timer_base) ; speed = 60*freq / ((360/step_angle)*microstep)
