A luminaire is provided that includes a head, a movement system, and a control system. The movement system rotates the luminaire head around an axis of rotation. The movement system includes a motor and a braking system. The motor rotates the head about the axis of rotation and the braking system can prevent rotation of the motor. The control system receives an Engage Brake command via a data link. The control system engages the braking system in response to the Engage Brake command by determining whether the motor is rotating, causing rotation of the motor to stop electrically when the motor is rotating, determining whether the motor has stopped rotating, engaging the braking system when the motor has stopped rotating, and removing power from the motor. When the motor is stopped, the control system may store in non-volatile memory a current absolute position of the luminaire head.
