Hello

i would like your help regarding a problem im facing with a sinamics drive 6RA8013-6DV62-0AA0 

I put in P50083 the value 3 in order to work with EMF because when i use encoder i get f60042 fault.

With this option the motor runs but i noticed that in r61 parameter with the encoder connected i see rpm after the motor reaches 450 rpm and its about the same as in parameter r21,and when the speed drops under 450 rpm i see 0

does anyone knows anything about this problem?

thank you in advance 

 Hi, are You using a tacho or an actual encoder?

Did You follow the advice for fault F60042 in the diagnostic document HERE?

Regards,

Graeme
