PF755 Break Frequency

I am having some trouble understanding what the break frequency is on a pf755. This is set in parameter 63. Rockwells description reads like the retro-encombobulator video. Can anyone explain it to me in laymen’s terms?

When creating a "custom" V/Hz pattern for your application (if necessary), the "break frequency" is the output speed (frequency) at which you want the V/Hz pattern to change in order to optimize the torque production against the motor heating effects. A higher V/Hz ratio can make a motor produce more torque, but also causes the motor to heat more. So if you NEED more torque at low speeds to overcome friction or "stiction", you can "boost" the V/Hz pattern for that purpose, but only when you are going slow. Then at some point you want to change that V/Hz patter to be more motor friendly, because once it is already moving, it takes less torque to KEEP it doing so. If you plot out that pattern on a graph (as they show in the manual for these functions), the point at which you make this change looks like you "breaking" the straight line, hence "break" frequency, because you are "breaking over" a knee point in the pattern.

This ONLY applies to when you are using V/Hz control, as opposed to Sensorless Vector Control or Flux Vector Control. which don't really need to do that.
