About Siemens MM430 inverter F002 alarm failure, the analysis is as follows -

1. F0002 is an overvoltage fault.

2, the cause of the failure -

1) The voltage of the DC link (r0026) exceeds the trip level (P2172);

2) The overvoltage is caused by the power supply voltage being too high or the motor is in the regenerative braking mode;

3) The ramp is falling too fast, or the motor is rotated by the large inertia load and is in regenerative braking state.

3, the solution -

1) Check the power cable and motor grounding of the motor to see if there is any broken cable or improper grounding.

2) Increase the values ​​of the ramp parameters P1120 and P1121 of the inverter.

3) Are you equipped with a braking resistor? If not configured, please pay attention to setting parameter P1240=1; if the braking resistor is configured, please pay attention to setting parameter P1240=0.

4) If your working conditions require faster braking performance and frequent braking, it is recommended that you configure the braking resistor (if you do not currently have it).
