E6582175M-613[Alarm information] Each message in the table is displayed to give a warning but does not cause the inverter to trip.Error code Name Description Remedies ST (assigned standby function) terminalOFF The ST-CC (or P24) circuit is opened.  Close the ST-CC (or P24) circuit. Undervoltage in main circuit  The supply voltage between R, S and T isunder voltage. Internal communication fault. Measure the main circuit supply voltage.If the voltage is at a normal level, theinverter requires repairing for fault. Retry in process  The inverter is in process of retry. A momentary stop occurred.The motor speed is being detected. The inverter restarts automatically. Becareful of the machine because it maysuddenly restart. Frequency point setting error alarm  The frequency setting signals at points 1and 2 are set too close to each other. Set the frequency setting signals at points1 and 2 apart from each other. Clear command acceptable  This message is displayed when pressingthe STOP key while an error code isdisplayed. Press the STOP key again to clear thetrip. Emergency stop command acceptable  The operation panel is used to stop theoperation in automatic control or remotecontrol mode. Press the STOP key for an emergencystop.To cancel the emergency stop, press anyother key./Setting error alarm /An error code and data are displayedalternately twice each. An error is found in a setting when data isreading or writing. Check whether the setting is madecorrectly./Display of first/last data items  The first and last data item in the data group is displayed. Press MODE key to exit the data group. DC braking  DC braking in process  The message goes off in several tens ofseconds if no problem occurs. Note 1)Flowing out of excess number of digits  The number of digits such as frequenciesis more than 4.(The upper digits have a priority.) Lower the frequency free unitmagnification . Deceleration stop function duringpower failure activated. The slowdown stop prohibition functionset with  (momentary powerfailure ride-through operation) isactivated. To restart operation, reset power supply orinput an operation signal again. Auto-stop because of continuousoperation at the lower-limit frequency The automatic stop function selected with was activated. This function is cancelled, whenfrequency reference reaches LL+0.2Hz oroperation command is OFF. Parameters in the process ofinitialization Parameters are being initialized to defaultvalues. Normal if the message disappears after awhile (several seconds to several tens ofseconds). Points setting alarm 1  In case of pt=7, there are same settingvalue at least two on parameter vl,f190, f192, f194, f196, orf198 except 0.0Hz. Set the points to different values. Points setting alarm 2  In case of pt=7, the inclination of V/f istoo high. Set the inclination of V/f to be flat.Note 1) When the DC braking (DB) function is assigned by using the input terminal function 22 or 23,it is normal if “” disappears when opening the circuit between the terminal and CC (or P24).
