THE MICRODRIVE CONTROLLER
The electronic controller is what you use to operate your power chair. It takes the battery voltage and sends it to the
appropriate system. The electronic controller also enables you to monitor battery charge, electronic controller functions,
and the condition of your electrical system. Also, it may be used to control some optional systems such as power elevating
seats and lights. The Microdrive electronic control system is a modular system. The electronics necessary to operate your
power chair are contained in several modules located on different parts of your power chair. Typically, the Microdrive
Controller is mounted to one of the armrests. See figure 30. The other components are located on or inside the power
base.
The controller supplied with your power chair has been pre-programmed to meet your needs. The program is set using
either a personal computer with software provided by the controller manufacturer or with a hand-held programmer, also
provided by the controller manufacturer.
WARNING! The controller program can affect speed, acceleration, deceleration, and braking. If it
is programmed incorrectly or outside of the safe limits as determined by your healthcare
professional, it can create a dangerous situation. Only the power chair manufacturer, an authorized
representative of the manufacturer, or a trained service technician should program the controller.
The Microdrive Controller consists of:
1. joystick
2. display pad
3. mode switch
4. on/off switch
5. speed adjustment dial
6. joystick interface module

Joystick
The joystick controls the direction and speed of your power
chair. When you move the joystick from the neutral (center)
position, the electromagnetic brakes release and allow the
power chair to move. The farther you push the joystick from
its neutral position, the faster the power chair moves. When
you release the joystick and allow it to return to the neutral
position, the electromagnetic brakes engage and the power
chair comes to a complete stop.
WARNING! If your power chair begins to
move in an unexpected manner,
immediately release the joystick. Unless
the joystick is damaged, this action
should stop your power chair.
