What to do if my Omron 3G3MX2 Inverter has tripped (ALARM LED is lit and "Exxx" is shown)?
If the Omron Inverter trips and the ALARM LED is lit with an error code (Exxx) displayed, press the STOP/RESET key to reset it. Identify the cause of the trip based on the error code and resolve it before restarting the operation.
Why does an Overcurrent Trip (E03) occur during Omron 3G3MX2 Inverter operation?
If an Overcurrent Trip (E03) occurs during the Omron Inverter's operation, it could be due to the acceleration time being too short or an excessive load. Try extending the Acceleration Time (F002/F202/ A092/A292) or reducing the load.
What to do if Omron Inverter motor does not turn after a RUN command is issued?
If the Omron Inverter motor does not turn after issuing a RUN command, the Rotation Direction Limit Selection (b035) might be set incorrectly, prohibiting forward or reverse rotation. Correct the setting for Rotation Direction Limit Selection (b035). Also, ensure the input terminal wiring for the RUN command or shorting-bar connection position is correct. Check the ON/OFF status of the input terminal with the Multi-function Input Monitor (d005). Finally, verify that the analog input for frequency reference or Variable Resistor wiring is correct by measuring the FV-SC terminal voltage or source-FI terminal current with a tester.
How to unlock parameters on Omron 3G3MX2 Inverter?
If parameters cannot be changed on the Omron Inverter, stop the Inverter and wait for the motor to fully decelerate before attempting to set them again. Alternatively, you can set the mode to "Data can be changed during RUN" (b031 = 10) to allow some parameters to be changed during operation. Also, ensure that Soft Lock Selection (b031) is disabled.
Why does my Omron Inverter motor turn in reverse?
If the Omron Inverter motor turns in reverse, the phase order of the motor wiring is likely incorrect. Reverse two of the wires connected to U/T1, V/T2, and W/T3, or adjust the motor phases to the correct order.
How to fix Omron Inverter when the power does not turn on?
If the Omron Inverter power does not turn on and the main POWER LED indicator is not lit, check if the shorting bar between terminals +1 and P/+2 or the DC reactor is disconnected and connect it. Also, check the input wire to ensure it is properly connected.
What to do if Omron Inverter Digital Operator keys do not work?
If the digital operator keys on the Omron Inverter do not work, it is possible that "86: DISP (Display fixed)" is allocated to a multi-function input terminal and that terminal is turned ON. Turn OFF the terminal to which this function is allocated.
Why does the earth leakage breaker trip when operating Omron 3G3MX2?
If the Omron Inverter leak current is large and causing the earth leakage breaker to trip, decrease the Carrier Frequency (b083).
How to reduce noise from Omron Inverter motor?
If the motor or machine connected to the Omron Inverter is loud, the carrier frequency might be low. Increase the Carrier Frequency (b083); however, be aware that this may increase noise or leakage current from the Inverter.
