User Manual of EM730 Series Inverter Fig. 7-35 Schematic Diagram of Frequency Hopping As shown in Fig. 7- 35, 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 Fig. 7- 35. The final frequency hopping range is (frequency hopping point 1 - hopping range 1, frequency hopping point 2 + hopping range 2).
