Brake control defective

What does F01630 mean?

The motor holding brake control is malfunctioning, posing a risk of uncontrolled motor movement. This can stem from an incorrect p1278 setting, disconnected or interrupted brake cables, a ground fault, or a short-circuit in the brake winding. A fault in the Safe Brake Relay, Control Unit, or Power Module could also be the cause.
