A similar arrangement will be used to drive the three LEDs showing if the head platform is at the horizontal, transitioning or vertical plane.<\/p>\n<p>The switch marked Pan\/Tilt Power, when operated will release the head brakes and light the associated LED, also, power will be applied to the speed controller enabling the joystick to operate the head at a variable speed set by turning the Speed Control knob, the advantage of using a pulse width modulated speed controller is that the motor does not lose torque at low speeds and will therefore not &#8216;stall&#8217;
