C57A1:brake release failure:Joint did not move or motor encoder is not functioning

Hi, there’s been a lot of trouble in UR5 these days. The first time you start your wrist2 in the morning, your wrist2 joints fail to unlock. Power off and restart the system can not eliminate the error, only by removing the cap on the joint, manually press the lock switch to unlock. Don’t know what causes this problem?

Sounds like a faulty brake coil to me. I’ve seen a couple of times before.

Sadly, it’s not possible to buy the brake parts separately.

Thank you for your answer. I agree with you very much. As far as I know, once the brake coil is manually pressed, the subsequent unlocking operation is normal, but the next morning when the first brake release, the coil suction will fail. Can this be handled by lubricating the coil slide?

Hello Zanxindq!
