A90 series Inverter User Guide When fault occurs, Press the STOP / RESET key to reset or enable the fault reset terminal to exit the fault state. if the fault has been eliminated, the inverter returns to the function setting state; if the fault has not been eliminated, the LED will continue to display the current fault code. If you can not solve the problem after handling the fault, please contact your dealer or company service personnel. When using the communication read fault code, the number corresponding to the fault number is "E" after the letter, and the number corresponding to "E01" is "01".
6.2 Failure analysis After power is on, due to improper function setting and incorrect wiring between inverter and external control terminals, motor cannot meet the expected working requirements. Fault analysis as described in this chapter can be taken as the reference to take the corrective actions. If trip codes appear, refer to 6.1 Troubleshooting. 6.2.1 The parameter parameter can not be set Press the up or down key to not change the parameter When the inverter is running, some parameters are not allowed to be modified and must stop to be modified. Press the Up key or Down key , the parameter display is variable, but the memory is invalid.
Some features of the code parameter set to a locked state, can not be modified. set the user password, there will be parameters can not be modified. When F12.02 is selected as 1 or 2, the limit parameter change will occur. Set F12.02 to 0. Or 6.2.2 Abnormal Motor Operation After pressing , motor does not run. Start/Stop is in the terminal control mode: Check the setting of F00.02. Coast-to-stop terminals is connected to COM: Disconnect Coast-to-stop terminals from COM. When the terminal (Run Command Switched to Terminal) is on and run command is only in terminal control mode: Switch the terminal off. 35 condition 3.Load loss protection parameter setting unreasonable.
3.Change the load detection level F07.22 and the detection time F07.23. E27 Accumulated Power-On Time is up The time of maintenance of the inverter is up Please contact your dealer for technical support. E28 Accumulated Running time is up The time of maintenance of the inverter is up Please contact your dealer for technical support. E57 Pipe overpressure The feedback pressure is too high for water supply applications. 1. Check if the sensor is abnormal. 2. Check whether the analog terminal can detect the analog input normally. 3. Check the external device.
