I have been searching the SEW website for a while now looking for an explanation of the operation of the BR style brakes used with their line of servo gear motors.
We have a machine that is less than two years old and has suffered four motor failures, two of which definitely seemed to be brake related. Now I am questioning the brake control circuit, which is a little different than my past experiences, and not too well understood by our contact at the OEM.
The OEM is also working on this problem for us, I just wanted to study the mfg docs and double check the circuit design and be able to test it. I have found literature for several other brake designs made by Sew Eurodrive, but not the BR series.
EDIT: The whole motor part number is FH47B/CM71M/BR/TF/RH1M/SB80
Any help appreciated.
