When stopping, the drive reference can be removed (i.e. Pr 1.11 = 0), but the brake will remain energized (open), until the motor has remained at a
speed below the brake apply speed for the delay defined by Pr 12.46. The delay prevents rapid activation and de-activation of the brake when fine
control of a motor is required close to zero speed.
