N Dodhia Posts: 8 Rating: (0)	Hello I have configured a 1FT6044-1AF71-3EH1 with Simotion D435. It gives me an eror F07900 (N, A) Drive: Motor locked/speed controller at its limit. What is the solution for this. How do I monitor the brakes.. How do I release my brakes... Is there brake Diagnostics? Thanks, Nayan.

When the drive is correct configured an the enable bits ar set the brake schouuld be open automatic. Can you post your brake configuration and specify your problem? Regards Christoph

N Dodhia Posts: 8 Rating: (0)	Hello Christoph, I have configured it as Motor Holding brake according to sequence control. When I run the motor in Control priority the shaft doesnot rotate , the torque shoots up and it gives me the following ALARM as mentioned above. I ran the motor at 1rpm but still the same problem. I thought the brake was not released. I am sending a scren shot. Waiting for your reply. Regards, Nayan. Attachment Braking.JPG (512 Downloads)
