F061 & 949 = 17

Hello,

On DC Drive 6RA70, I have fault F061, 949=17 

When I switch from 7.0 to get 1.1 motor starts, (not good), and because of F061,armature contactor before drive go out and motor stops.

I changed Thyristors,two times, Card A7002, no result. I connected motor with same drive, status was 1.1 without fault(this drive is in use i cannot change the drive)

Please for suggestion what else should I check.

Thanks

Hello,

On DC Drive 6RA70 280 Amp DC, I have fault F061, 949=17

When I switch from 7.0 it is showing 3.0 (thyristor check mode P 830=2) and trips on F061 with fault value 17.

I changed Thyristors,two times (with all new thyristors blocks), NO RESULT, then changed Card A7002, no result, then changed CUD again same fault. I connected motor with another same drive, status was running ok without fault (this drive is in use i cannot change the drive)

fault value r 47.01 is 17 and r 47.02 is 252. I could not understand the meaning of r 47.02 = 252. Not written in manual.......

Please for suggestion what else should I check.

Thanks JASMIN
