Setting parameters04/07 AWB8230-1541GBX Activate digital inputs 3 and 4 (= FF3).X Repeat your input with the arrow keys.X Press the ENTER key to save the value in PNU A023.If you have configured further digital inputs with FF3 and FF4(PNU C001 to C005), you can enter up to 15 fixed frequencies. TheDF51 saves these values in PNU A021 to A035 (a table 24).Motor potentiometerWith the UP and DWN (down) signals, you can enter the referencefrequency using an electronic motor potentiometer.The UP <strong>com</strong>mand accelerates the drive up to the limit value f max(PNU F001) at the acceleration ramp set with PNU F002.The deceleration (DWN) down to 0 Hz takes place at thedeceleration ramp set with PNU F003.DWNUPREVFWD4 3 2 1P24FWD/REVUPFigure 98:Control using electronic motor potentiometerDWNX Because the terminal functions UP and DWN can be used onlywhen the reference frequency has been specified withPNU F001 or A020, you need to make sure that PNU A001contains the value 02.X Configure two of the digital inputs 1 to 5 as UP or DWN bysetting the corresponding PNU (C001 to C005) to 27 (UP) or 28(DWN).Through the use of the input configured as UP, the referencefrequency set under PNU A020 is also increased or, with DWN,reduced (a fig. 99).The shortest permissible duration during which an UP or DWNinput must be active is 50 ms.The current reference frequency is saved when parameterPNU C101 contains the value 01. It remains in memory even in theevent of a power cut (POWER OFF).The UP/DWN function is not available when jog mode has beenactivated (with active JOG input) or when the reference frequencydefinition is made through the analog input terminals.The output frequency range for UP and DWN ranges from 0 Hz upto the end frequency specified under PNU A04 (a section “Endfrequency”, page 68).To operate the electronic motor potentiometer through controlsignal terminals, microswitch TM/PRG must be in its PRG position.You can also use the electronic motor potentiometer function withthe arrow keys (Í and Ú) of keypad.X In PNU A001 enter the value 02 and save your input with theENTER key.X Select PNU A020 and press the PRG key to open it.X Enable a direction of rotation for the Motor (for example withthe default settings by setting digital input 1 = FWD).X With the arrow keys (Í and Ú), set the required frequency value.Figure 99:f reff o : Output frequencyFunction chart for UP/DWN (acceleration/deceleration– motor potentiometer)If you are using the keypad, you save the set reference frequencywith the ENTER key. PNU C101 is not used in this control mode.94
