C3902 Error during abrasion of brake

Torque of the amplifier is reduced
Axis is mechanically blocked
Axis is at end stop or runs towards it
Abrasion of brake is impossible because motor
generates less torque than holding torque of brake
Sum of weight load and brake torque is greater than
motor peak torque
