And I too would like to see more documentation as well. I was severely disappointed when I saw how little there was.

Andrew,
There was quite a bit more documentation on the Jaguars including schematics available on the Luminary website.
As to the output frequency vs response. The brush/commutator length converts into a repetitive frequency calculation dependent on speed for each motor. All KOP motors are not the same brush/commutator design. The FP is significantly different than the CIM. The difference in output frequency of the controller determines how effectively the controller can make current changes in the winding it is connected to, through the brush assy. The higher frequency may interact differently on a particular motor due to winding inductance or the number of voltage transitions it would make while connected to one particular winding. The mass of the armature also comes into play when comparing motors as does the mechanical load on said motor. While the Jaguar may be more "linear" on one type of motor than the Victor, it might not be on another. Take a close look at the motor curves and then try to interpolate different loads into the response.
