F0002 Fault

The application sounds ok. This is interesting problem, keep me posted with progress.

Thanks

It is a CNC machine(wheel turning lathe) .

Motor has an  ABB brand (75KW).and its running current about 43A.

Is this problem from begining of machine or recently faced?

If recently, have you replaced any supply line side component?

Which is controller?

Which type of infeed module for axes drives?

Is any capacitor module connected across axes DC bus?

Have you followed Siemens recomandations for installation of line side components in Axes drives as well as MM drive supply connection?

If possible could you please attach electrical wiring connection side?

One further thought..

Check to see if any Power Factor Correction (PFC) units are connected to the came supply?

PFC capacitors are designed to operate out of the normal harmonic frequencies, however these devices age over time and can drift into the harmonic currents generated by power supply and drive systems, creating either a sink for currents or a tuned circuit which can amplify the distortion.

A quick test for PFC which may be causing trouble on a supply line is to switch it off at the local disconnector. If the problem goes away this will be the place to look.

PFC should be on a periodic service schedule, but are often forgotten about or lost within the site modifications, ageing capacitors can explode or just quietly expire taking the supply fuse with it hence the need for periodic servicing.

I hope you are managing this problem ok.

Hi everyone !

i want to tell you that F002 error still exist my micromaster drive.actually i have serviced it from the man but i could not get ride of that problem. now today i open its front cover and measure its DC voltages that was ok(mean its value was 615 according to input supply but at vfd dispaly (parameter 26 was showing 1025 ) so it mean that this is not an DC Over voltage issue but it is some hardware(in control card) issue. 

some one can tell me that which control card should be replace or repair because it is very difficult to remove the vfd and go to some one to repair it because main city is very far away form that site.

Hello,

The dc link voltage is measured thru the X60 connector on the PSB board(6SL3352-6BE00-0AA1) which is behind the controller CIB board  So check for any loose connection or try by replacing PSB board.

Finally i remove the fault (F0002). Actually it was due to  some SMD issue on A5E006677643 card.now the drive is running with full confidence ..

I thanks to all experts who give me a precious advice about this...
