Programming the ControlSignal Terminals01/02 AWB8230-1413GBActivate/deactivate PID control Reset PID <strong>and</strong> integral<strong>com</strong>ponent (PIDC)With the digital input configured as PID, PID control can beswitched on <strong>and</strong> off. For a detailed description of the built-in PIDcontroller, a section “PID control”, page 116. To use the PIDinput for activating <strong>and</strong> deactivating PID control, the PID controllermust be switched on with PNU A071 = 1 (a section “PIDcontrol active/inactive”, page 119). When the PID input isactivated, the PID controller is switched off <strong>and</strong> the frequencyinverter works with “normal” frequency control.With the digital input configured as PIDC, the integral <strong>com</strong>ponentof the PID control can be reset. If the PIDC input is activated, theintegral <strong>com</strong>ponent is reset to zero.hThe PID <strong>and</strong> PIDC inputs are optional. If you want PIDcontrol to be active all the time, you only need to setPNU A071 to 1.Figure 86:PIDC2PID1X Program one of the digital inputs 1 to 5 as PID by entering thevalue 23 under the corresponding PNU (C001 to C005).X Program one of the digital inputs 1 to 5 as PIDC by entering thevalue 24 under the corresponding PNU (C001 to C005).FWDFWP24Digital input FW configured as FWD (start/stop clockwiseoperation), digital input 1 as PID (activate/deactivateswitch PID control) <strong>and</strong> 2 as PIDC (reset integral<strong>com</strong>ponent)hhDo not switch the PID controller on <strong>and</strong> off while thefrequency inverter is in RUN mode (RUN lamp is lit).Do not reset the integral <strong>com</strong>ponent of the PID controllerwhile the frequency inverter is in RUN mode (RUN lamp islit), as this can lead to overcurrent tripping.92
