12.8 Automatic Error AcknowledgmentThe automatic error acknowledgment enables acknowledgment of the faults OvercurrentF0500, Overcurrent F0507 and Overvoltage F0700 without intervention by anoverriding control system or the user. If one of the these errors occurs, the frequencyinverter switches off the power semi-conductors and waits for the time defined by theparameter Restart Delay 579. If the error must be acknowledged, the speed of themachine is determined via the quick catching function and it is synchronized to therotating machine. The automatic error acknowledgment makes use of quick catchingoperation mode, regardless of the parameter for search run, Operation Mode 645.The information given on this function in chapter "Search run" must be observed.With parameter Allowed No. of Auto-Acknowl. 578, you can define the number ofautomatic error acknowledgements which are permitted within 10 minutes.An acknowledgement repeated above the permissible number within 10 minutes willresult in the frequency inverter being switched off. The errors Overcurrent F0500,Overcurrent F0507 and Overvoltage F0700 have a separate error acknowledgementcounter.ParameterSettingsNo. Description Min. Max.
