How to troubleshoot low-voltage protection on Omron SYSDRIVE 3G3XV-EV2 Inverter?
If your Omron Inverter is showing a low-voltage protection error (main circuit voltage insufficient), it's likely due to a drop in input voltage. Check the input power supply voltage using a tester. If the voltage is low, adjust the input voltage.
What does external fault signal input mean on Omron SYSDRIVE 3G3XV-EV2 Inverter?
If the Omron Inverter is showing an external fault signal input, it means an external fault condition has occurred. Correct the cause of the fault input.
What causes simultaneous forward and reverse rotation commands on Omron Inverter?
If the Omron Inverter is receiving simultaneous forward and reverse rotation commands, it could be due to an operation sequence error or a 3-wire/2-wire selection error. Recheck the control sequence and constant settings (No. 32).
