01/02 AWB8230-1413GB Start/stopReset (RST)A fault message can be acknowledged by activating <strong>and</strong>subsequently deactivating (i.e. resetting) the digital inputconfigured as RST.RSTf 12 msRSTK144P24~ 30 msFigure 67:Digital input 4 configured as RST (reset)Figure 68: Function chart for RST (reset)K14: Signalling relay contact K14X Program one of the digital inputs 1 to 5 as RST by entering thevalue 18 under the corresponding PNU (C001 to C005).By default, RS is assigned to digital input 1.Under PNU C103, you can select how the frequency inverterresponds after the reset signal drops out. You can specify whetherthe frequency inverter synchronizes to the frequency set underPNU b007 or starts at 0 Hz.PNU 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. This time can also beused in conjunction with the FRS function. During the delay,the following message appears on the LED display:1.0b007 Synchronizing – j 0 to 400 Hz <strong>Frequency</strong> at which a restart is initiated. 0.0frequencyC102 Reset signal j j 00 Reset signal issued on a rising edge 0001 Reset signal issued on a falling edge02 Reset signal issued on a rising edge, only if fault signalpresentC103 Behaviour on – j 00 0 Hz start 00reset01 Synchronization to the motor speedhWarning!If a reset is carried out after a fault, the motor will startimmediately if a start signal is applied simultaneously. Toavoid the risk of serious or fatal injury to personnel, youmust ensure that the start signal is not present beforeacknowledging an error message with a reset .When a fault has occurred, the OFF key on the keypadacts as a RESET key, <strong>and</strong> can be used instead of the RSTinput to reset the fault.hhhThe RST input is always a make (NO) contact <strong>and</strong> cannotbe programmed as a break (NC) contact.Alternatively, you can acknowledge a fault message bybriefly switching the supply voltage off <strong>and</strong> on again.If a reset is initiated during operation, the motor coasts toa stop.hIf the RST input is active for more than four seconds, it cancause a false trip.77
