Instructions for using the
conversion graph
Slope values must be entered in rad/s
2
(see Figure 28 for conversions).
• Determine your desired end speed ∆N in rpm and the necessary time
period ∆t in seconds (s).
• Mark the point corresponding to the combined values of ∆N and ∆t on
the graph.
• Draw a straight line through the marked point and the origin of the
graph.
• Read the slope of your desired ramp in rad/s
2
at the intersection of the
straight line and the RAMP axis and enter the respective RAMP
parameter (see example).
RAMP = π/30* ∆N/∆t*min/s (∆N in rpm and ∆t in s)
