User Manual of EM760 High-Performance Inverter As shown in the figure above, the frequency hopping function is set in the form of “frequency hopping point + hopping range”. The specific frequency hopping range is (frequency hopping point - hopping range, frequency hopping point + hopping range). At most three frequency hopping areas can be set. When the respective hopping range is 0, the corresponding frequency hopping function will be invalid.
When the frequency hopping function is valid and the set frequency rises within the regulation range, the final set frequency is “frequency hopping point - hopping range”; and when the frequency hopping function drops, the final set frequency is “frequency hopping point + hopping range”. Multiple frequency hopping areas can be superimposed, as shown in the frequency hopping areas 1 and 2 in the figure above. The final frequency hopping range is (frequency hopping point 1 - hopping range 1, frequency hopping point 2 + hopping range 2).
6.6.6 Analog level detection (ADT) The analog level detection function is used to detect and monitor the analog input ofthe current selected F15.25 channel, and also perform internal operation and external alarm monitoring. Two detection conditions can be set, but only one analog input channel can be detected.
