The functions can beconfigured to sample and hold either the largest (maximum) or smallest(minimum) value of the input signal selected by this parameter.Important: Either real or integer data sources can be selected, but integersources will be internally converted to real and displayed in the peak detectoutput as real numbers.1043 755 PkDtct2PresetSelPeak Detection 2 Preset SelectSelects the preset data source for the peak detect functions. The output of theeach peak detect function can be forced to equal the value of the input signalselected by this parameter by using the “Peak1 Set” bit in P1039 [Peak1 Cfg].The same integer to real number conversion applies to both the input and thepreset signal.1044 755 Peak2 CfgPeak 2 ConfigureConfigures operation of each peak detector.ValuesDefault: 1035Min/Max: 0 / 159999Default: 0Min/Max: 0 / 159999Read-WriteData TypeRW 32-bitIntegerRW 32-bitIntegerDIAGNOSTICSPeak DirectionOptionsReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedPeak1 SetPeak1 HoldPeak1 PeakDefault 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 00 = False1 = TrueBit 0 “Peak1 Peak” – 0 = Capture minimum value of the input signal. 1 = Capture maximum value of the input signal.Bit 1 “Peak1 Hold” – 0 = Monitor input. 1 = Ignore input and hold output at present value. This bit is overridden by Bit 2.Bit 2 “Peak1 Set” – 0 = Resume normal capture of the input signal value (assuming Bit 1 is also = 0). The preset signal will be used as a starting valueto compare against further changes in the input signal level. 1 = Force output of the peak detect function to equal the signal selected by[PkDtctXPresetSel].1045 755 Peak 2 ChangePeak 2 ChangeStatus of the peak detectors.OptionsReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedReservedPeak1ChangeDefault 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 00 = Output value is held or set.1 = Output value has changed.1046 755 PeakDetect2 OutDefault: 0.000000Peak Detection 2 OutputDisplays the output of the peak detector, according to the operation selected bythe configuration bits, and is always displayed as a real number, regardless of theselected signal type.Min/Max: –/+21478000.000000RORealPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
