sumit saha Posts: 2 Rating: (0)	Dear Sir, Currently in our plant I am facing one Drive tripping problem with falut f0002. For the last 2years we are using similar type 18nos of sinamics V50 drive of 160kw, 302A output(6SL3710-1BD33-0ANO-Z) which are connected to 132kw air blower motor. Speed is controlled by pressure transmitter through profibus. For the past one week one blower has tripped with f0002 fault for two times during running condition. I have checked p1120, 1121 is 120sec, p1240 is 1, no DBR is not present. Please let us know possible cause and suggest what step we can take to prevent such tripping. Thanks...

Probook Posts: 4 Rating: (0)	you can use the MM4 parameter list manual for F0002 check. link: https://support.automation.siemens.com/CN/llisapi.dll?aktprim=0&lang=en&referer=%2fCN%2f&func=cslib.csinfo&siteid=csius&treeLang=zh&groupid=18886884&extranet=standard&viewreg=CN&nodeid0=10804928&objaction=csopen Description as below: F0002 Overvoltage STOP II Quit Refer to F0001 Cause - DC link voltage (r0026) higher than the overvoltage threshold (refer to parameter r0026) - ground fault Diagnosis & Remedy Please check the following: - is the line supply voltage within the permissible range? - has the DC current DC link monitoring been enabled (P1240) and correctly parameterized? - extend the deceleration ramp (ramp-down time P1121, P1135) - remove the ground fault - is the required braking power within the permissible limits? NOTE - a higher moment of inertia requires longer deceleration times; if required, use a braking resistor. - overvoltage can either be caused by an excessively high line supply voltage or by the fact that the motor is generating (regenerative mode). - the motor can be generating as it is decelerating quickly or due to the fact that an active load is driving the motor.

Try to increase P1243 from defualt setting P1243=100% to up to 150% and observe the load current...
