9000 series
Inductive sensing joysticks
Overview
The 9000 series joystick operates by passing an oscillating current through a drive coil, directly mounted at
the lower end of the operating lever, and immediately above the four sensing coils. When the shaft and drive coil moves away from
the center, the signals detected in each opposing pair of coils increase nominally in proportion to deflection. The phase of those
signals determine the direction. Synchronous electronic switches followed by integrating amplifiers provide DC signals directly equiv-
alent to those of potentiometer joysticks, but with fixed output impedance and free of wiper noise and track wear.
Designed for use in the most safety-critical applications, the 9000 series incorporates comprehensive internal monitoring circuitry
whereby output signals are continually compared with separately generated ‘mirror signals’. In the unlikely event of an internal fault,
the dual decode system will generate a separate fault signal, enabling the controller to fail-to-safe. The dual decode system is a
complete internal self-monitoring system, providing a far higher standard of protection. An additional,‘away from center’ signal is also
available whenever required. Although the monitoring of the joystick is fully internal, the inverse ‘mirror signals’ can be available as
external outputs where the monitor function is incorporated within the controller circuitry.
The 9000 series may also be specified with guided feel. A joystick with guided feel moves more readily towards the poles ( N, S, E and
W ) and while it can still move away from the poles, the force required to do so is greater. Unless specified otherwise, joysticks are
supplied as standard without guiding. This standard configuration allows the user to move the joystick anywhere within the limiter with
the same force and without any bias.
The 9000 series can be configured in three different modes:
• Orthoganol, standard signals - Replicating that of a potentiometer.
• Deliberate signal mixing - Ideal for those applications whereby the method of steering is by controlling two motors. For example one
motor uses X+Y signals and the other uses X-Y signals. This mixing is achieved by internally orientating the signals at 45º to normal.
Typical applications may be twin propeller boats, tracked vehicles, or wheelchairs.
• Deliberate signal interaction - Enables reduction in one signal as the other increases. This option is
particularly beneficial where it is undesirable to maintain full forward speed while turning and vice versa.
