Constants 2 and 3 are described as minimum and rated rotor speed, but then they are used as minimum/maximum generator speeds. The issue is especially problematic when you specify an overspeed percentage, because that is calculated from the rotor speed but applied to the generator speed so things die.
Moreover, there might be an error in the equation converting LSS speed to HSS speed. (line 464)
