The SR469 will take the information provided and create protection curves for any voltage between the minimum and 100%. For values
above the voltage in question, the SR469 will extrapolate the safe stall protection curve to 110% voltage. This current level is calculated
by taking the locked rotor current @ 100 voltage and multiplying by 1.10. For trip times above the 110% current level, the trip time of
110% will be used. (see Figure 4-13)
Figure 4-13 VOLTAGE DEPENDENT OVERLOAD PROTECTION CURVES
Note: The safe stall curve is in reality a series of safe stall points for different voltages. For a
given voltage, there can only be one value of stall current and therefore, only one safe
stall time.
