When the inverter stops unexpectedly during operation: the inverter will stop automatically, the running indicator will stop the motor and stop automatically, the inverter running indicator will be on, and the frequency will run. The possible reasons are as follows:
1. There is a faulty alarm at the flashing prompt. Find the cause of the failure and reset the fault.
2. Simple plc but the loop is complete, waiting for the next command. Check the PLC settings.
3. The communication between the remote control and the inverter is interrupted. Check the communication line.
4. The externally input R, S, and T power supplies are interrupted. Check the power supply.
5. Run the command channel switch. Check the running command channel related function code settings.
6. The positive and negative logic of the control terminal changes. Check that the P038 settings meet the requirements.
7. The fault is automatically reset. Check the auto reset settings and the cause of the fault.
8. Set the frequency to 0. Check the set frequency.
9. External Interrupt. Check the external interrupt settings and the source of the fault.
10. The simple PLC is suspended. Check the PLC terminal function.
11. Power failure restart, select instantaneous low voltage compensation, and the power supply voltage is low,
Check the power failure function to restart the setup and input voltage.
