1. 

Construct a custom curve for the running overload thermal limit. If the curve does not extend to the acceleration thermal limits, extend
it such that the curve intersects the acceleration thermal limit curves. (see Figure 4-11)

 
2. 

Enter the per unit current value for the acceleration overload curve intersect with the custom curve for 80% line voltage. Also enter the
per unit current and safe stall protection time for 80% line voltage. (see Figure 4-12)

 
3. 

Enter the per unit current value for the acceleration overload curve intersect with the custom curve for 100% line voltage. Also enter
the per unit current and safe stall protection time for 100% line voltage. (see Figure 4-12)
