E6582175F-8665) Adjusting feedback valueMake adjustment by converting input level of the feedback value into frequency. Refer to section 6.10.2 fordetails.Example of 0 - 10 Vdc voltage inputsettingExample of 0 - 10 Vdc voltage inputsettingExample of 4 - 20 mAdc voltage inputsetting(60Hz)(0Hz)0V0%10V100%VIA input valueOutput frequency13(60Hz)11(0Hz)0V100%5V12100%VIB input valueOutput frequency19(60Hz)17(0Hz) 4mA1620%20mA18100%VIC input valueOutput frequency6) Setting the time elapsed before PID control startsWaiting time until starting PID control system can be set to avoid PID control until the control systembecomes stable.The inverter ignores feedback value, carries out operation at the frequency determined by the frequencycommand value for the period of time specified with f359, and enters the PID control mode after theelapsed time.7) PID control forward/reverse characteristic switchPID input characteristics can be reversed.PID set valueFeedback value×(-1)PID OutputOpposite characteristicOriginal characteristicCharacteristic selection (parameter or terminal input) When characteristic is reversed according to parameters, set PID forward/reverse characteristicsselection f380 to 1: Set reverse characteristics. When characteristic is reversed using logic input terminal, assign function number 54/55, PIDcharacteristics switching, to an input terminal.Note) If reverse characteristics is selected for parameter f380 and terminal input at the same time,they become forward characteristic.
