04/07 AWB8230-1541GB Reference and control signalinputsHigher-priority control signals allow the reference source selectedwith PNU A001 (F-COM) to be temporarily exceeded.Example: When a fixed frequency (CF1 to CF4) is activated, theanalog reference value of control signal terminals O or OI isoverwritten.Priority Reference input source Description(page)1 (highest) Fixed frequency FF1 to FF4 932 Digital input = 31 (OPE) 983 Digital input = 51 (F-TM) 984 Digital input = 16 (AT) 875 Microswitch TM/PRG in positionTM6 (lowest) PNU A001 81The starting signal selected with PNU A002 (OPE mode) can alsobe temporarily overwritten with higher-value control signals:Priority Source for Start (RUN) signal Description(page)1 (highest) Digital input = 31 (OPE) 982 Digital input = 51 (F-TM) 983 Microswitch TM/PRG in positionTM4 (lowest) PNU A002 72Basic parametersInput/indication of frequency reference valuePNU F01 always indicates the current reference frequency. Bydefault, this is the analog reference value for control signalterminals O and OI (PNU A01 = 01). With PNU A01 = 02 you canspecify the reference frequency directly with the arrow keys Í/Ú.5151The set value is automatically written to PNU A020. There you canchange the value with arrow keys Í/Ú and confirm it with theEnter key. You can save additional reference frequencies inPNU A021 to PNU A035 and call them up through the controlsignal terminals a section “Fixed frequencies”, page 93.hhFigure 75:If one or more of the fixed frequencies exceeds 50 Hz, youmust first increase the end frequency with PNU A004(a section “End frequency”, page 70).With PNU F001, you can change the reference value evenwhen parameter protection has been set with PNU b031.Micro switch TM/PRG must be in the TM position.P24 CM2 12 11TM microswitchIf you have not activated any fixed frequencies, PNU F01 indicatesthe set reference frequency.If you specify the reference frequency with PNU A020, you canenter a new value under PNU F001, which is saved automaticallyin PNU A020:X Change the current value with the arrow keys.X Save the modified value with the ENTER key.The saved value is automatically written to PNU A020.SRSK485OPETMPRGPNU Designation RUN b031= 10Value Function DSF001Referencevalue, inputthroughkeypadj j <strong>Frequency</strong>:0.0…400 Hz(0.1 Hz)Resolution g0.1 HzThe reference value can be defined using various methods:• With PNU F001 or A020: Enter the value 001 under PNU A02.• With the potentiometer on the keypad: Enter the value 00 underPNU A01.• With a 0 to 10 V voltage signal or a 4 to 20 mA current signal atanalog input O or OI: Enter the value 01 under PNU A01.• With the digital inputs configured as FF1 to FF4. After selection of therequired fixed frequency stage using FF1 to FF4, the frequency for therespective stage can be entered.The display of the reference value is independent of which method wasused to set the reference value.0.073
