Hi tkosam, thinking about this, it will be the poles in the wind generator. You will have another parameter that should be the generator revs per minute at which the controller will brake the generator to stop the generator over-reving and supplying too much voltage to the controller.
The controller will be sensing the ripple in the voltage (or pulse in the voltage) coming from the generator and dividing it by the Pole Logarithm value to calculate the RPM of the generator. As the speed of the generator increases the generator voltage will also increase, and the controller will start braking the generator once the generator gets to a certain RPM.
