# Geneva indexing mechanism
# Scope: External Geneva indexing and dwell fractions for a uniform driver.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

slots = 6

indexAngle := 2*pi/slots [rad]
engagement := (pi-2*pi/slots)/(2*pi)
cycle := 2*pi/speed [s]
dwell := cycle*(1-engagement) [s]

check positive dwell: dwell > 0 s

scenario alternative: slots = 5
