20-81 PID Normal/Inverse ControlOption: Function:[0] * Normal[1] InverseNormal [0] causes the frequency converter’s output frequencyto decrease when the feedback is greater than the setpoint ref-erence. This is common for pressure-controlled supply fan andpump applications.Inverse [1] causes the frequency converter’s output frequencyto increase when the feedback is greater than the setpoint ref-erence. This is common for temperature-controlled cooling ap-plications, such as cooling towers.7.1.11.
