Reset method of protective function5 TROUBLESHOOTINGWhen an alarm (major failures) occurs in the inverter, the protective function is activated bringing the inverter to analarm stop and the PU display automatically changes to any of the following error (alarm) indications.If your fault does not correspond to any of the following errors or if you have any other problem, please contact yoursales representative.• Retention of alarm output signal.................. When the magnetic contactor (MC) provided on the input side of the inverter isopened at the activation of the protective function, the inverter's control powerwill be lost and the alarm output will not be held.• Alarm display ........................................... When the protective function is activated, the operation panel displayautomatically switches to the above indication.• Resetting method............................................When the protective function is activated, the inverter output is kept stopped.Unless reset, therefore, the inverter cannot restart. (Refer to page 91.)• When the protective function is activated, take the corresponding corrective action, then reset the inverter, andresume operation.Not doing so may lead to the inverter fault and damage.Inverter alarm displays are roughly divided as below.(1) Error messageA message regarding operational fault and setting fault by the operation panel (FR-DU07) or parameter unit (FR-PU04/FR-PU07) is displayed. The inverter does not trip.(2) WarningsThe inverter does not trip even when a warning is displayed. However, failure to take appropriate measures willlead to a major fault.(3) Minor faultThe inverter does not trip. You can also output a minor fault signal by making parameter setting.(4) Maijor faultWhen a fault occurs, the inverter trips and a fault signal is output.5.1 Reset method of protective function(1) Resetting the inverterThe inverter can be reset by performing any of the following operations. Note that the internal thermal integrated valueof the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.Recover about 1s after reset is cancelled.Operation 1: ..... Using the operation panel, press to reset the inverter.(Enabled only when a fault occurs. (Refer to page 97 for major fault.))Operation 2: ...... Switch power off once, then switch it on again.Operation 3: . .... Turn on the reset signal (RES) for more than 0.1s. (If the RES signal iskept on, "Err." appears (flickers) to indicate that the inverter is in a resetstatus.)ONOFFInverterRESSDTROUBLESHOOTING591
