9.3 REFERENCESYou can use the Preset frequencies function in processes where more than 1 fixed frequencyreference is necessary. There are 8 preset frequency references available. You can make theselection of a preset frequency reference with the digital input signals P3.5.1.15, P3.5.1.16,and P3.5.1.17.P3.3.10 PRESET FREQUENCY MODE (ID182)With this parameter, you can set the logic which one of the preset frequencies is selectedinto use. There is a selection of 2 different logics.Selectionnumber Selection name Description0 Binary codedThe mix of the inputs is binary coded. The different sets ofactive digital inputs determine the preset frequency. Seemore data in Table 59 The selection of preset frequencieswhen P3.3.10 = Binary coded.1 Number (of inputs used) The number of active inputs tells which preset frequency isused: 1, 2 or 3.P3.3.12 PRESET FREQUENCY 1 (ID180)P3.3.13 PRESET FREQUENCY 2 (ID106)P3.3.14 PRESET FREQUENCY 3 (ID126)P3.3.15 PRESET FREQUENCY 4 (ID127)P3.3.16 PRESET FREQUENCY 5 (ID128)P3.3.17 PRESET FREQUENCY 6 (ID129)P3.3.18 PRESET FREQUENCY 7 (ID130)To make a selection of a preset frequency between 1 and 7, give digital inputs to P3.5.1.15(Preset Frequency Selection 0), P3.5.1.16 (Preset Frequency Selection 1), and/or P3.5.1.17(Preset Frequency Selection 2). The different sets of active digital inputs determine thepreset frequency. You can find more data in the table below. The values of the presetfrequencies stay automatically between the minimum and maximum frequencies (P3.3.1 andP3.3.2).Necessary step Activated frequencyMake a selection of the value 1 for parameter P3.3.3.
