These parameters set analog input value and maximum output frequency (01-00, used in open-loop control) or the corresponding function of the detection reference value (10-01, used in PID closed-loop control). They divide output frequency into several sections according to Pr.04-26 to Pr.04-29. There is an independent gain and minimum output frequency in every section. We can reduce inferior products and improve working efficiency via parameter modification. For example, we set frequency via two groups analog input terminals. When the frequency we set is 0-15Hz and the gain is 50%, the minimum output frequency will be 5Hz; when the frequency we set is 15-35Hz and the gain is 80%, the minimum output frequency will be 15Hz; when the frequency we set is 35-50Hz and the gain is 150%, the minimum output frequency will be 35Hz as the following diagram shows.
