Programming the ControlSignal Terminals01/02 AWB8230-1413GBController inhibit <strong>and</strong> coasting (free run stop – FRS)If you activate the digital input configured as FRS, the motor isswitched off <strong>and</strong> coasts to a stop (for example if an Emergency-Stop is made). If you deactivate the FRS input, then, depending onthe inverter’s configuration, the frequency output is eithersynchronized to the current speed of the coasting motor or restartsat 0 Hz.X Use PNU b088 to specify whether the motor is to restart at 0 Hzafter the FRS input has been deactivated, or if synchronizationshould take place after a waiting time specified underPNU b003. The frequency inverter recognizes the speed of therotor <strong>and</strong> starts only when the frequency set at PNU b007 isreached.X Program one of the digital inputs 1 to 5 as FRS by entering thevalue 11 under the corresponding PNU (C001 to C005).FWDFRSFW 3P24Figure 61:Digital input 3 configured as FRS (controller inhibit) <strong>and</strong>FW as FWD (start/stop clockwise operation)FWD/REVFRSabn Mct wFigure 62: Function chart for FRS (control inhibit <strong>and</strong> free run stop)n M :Motor speedt w : Waiting time (setting under PNU b003)a Motor coasts to a stopb Synchronization to the current motor speedc Restart from 0 HzPNU Name Adjustable in RUN mode Value Function WENormalExtendedb003Waiting timebefore restart– j 0.3 to 100 s Here, set a time which is to expire before an automaticrestart is initiated after a fault signal.
