Seeady66 is correct, that is how you can calibrate a 7090 for the 7096/7095 so the speeds are not too low and the pump stalls.
Ramp is tenths of a second, it is a 0-X ramp up that accelerates the impeller, the purpose is to reduce noise so instead of a harsh off and on, the impeller is eased on. It really is only a noise reduction setting.
