F0002 OverVoltage fault in siemens micromaster 430 or MM430 drive

-

 How can resolve problem F0002 Over Voltage fault in siemens micromaster 430 or MM430 drive ?

Cause : Over Voltage .

- DC-link controller disabled (P1240 = 0)

- DC-link voltage (r0026) exceeds trip level (P2172)

- Overvoltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be caused by fast ramp downs or if the motor is driven from an active load.
