5 PROTECTIVE FUNCTIONSThis chapter describes the basic "PROTECTIVE FUNCTION" foruse of this product.Always read the instructions before using the equipment5.1 Reset method of protective function........................3725.2 List of fault or alarm display ....................................3735.3 Causes and corrective actions ................................3745.4 Correspondences between digital and actualcharacters ...............................................................3895.5 Check first when you have troubles ........................3901234563717
Reset method of protective functionWhen a fault occurs in the inverter, the inverter trips and the PU display automatically changes to any of the following fault oralarm indications.If the fault does not correspond to any of the following faults or if you have any other problem, please contact your salesrepresentative.• Retention of fault output signal...When the magnetic contactor (MC) provided on the input side of the inverter is openedwhen a fault occurs, the inverter's control power will be lost and the fault output will not beheld.• Fault or alarm indication...........When a fault or alarm occurs, the operation panel display automatically switches to the faultor alarm indication.• Resetting method.....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the invertercannot restart. (Refer to page 372)• When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.Not doing so may lead to the inverter fault and damage.Inverter fault or alarm indications are roughly divided as below.(1) Error messageA message regarding operational fault and setting fault by the operation panel (FR-DU07) and 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 will lead to afault.(3) AlarmThe inverter does not trip. You can also output an alarm signal by making parameter setting.(4) 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.(This may only be performed when a fault occurs (Refer to page 378 forfault.))Operation 2:...... Switch power off once, then switch it on again.ONOFFOperation 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.)InverterRESSD372
