Specifying a deadband
Mechanical vibrations in the work environment and joystick noise can generate
small joystick output signals when the joystick is at rest. These signals can result
in unintended axis motions. A deadband can be created around the joystick’s
rest (zero) position to prevent these axis motions.
Create the desired
deadband around each
axis zero position by en-
tering the minimum percentage of the total joystick range of motion required to
cause axis motion.
The default deadband is 18% of the joystick’s total range of motion.
Calibrating the joystick
The full range of joystick motion must be calibrated for optimum control. To
calibrate the joystick:
1 Click the Teach button. The Joystick Teach wizard will be displayed.
2 Follow the instructions provided by the wizard screens.
Viewing calibration values
Joystick calibration values will fall somewhere between a low
of 0 and a high of 5.0. Click the View Calibration button to
display the current values.
The Min and Max values should be almost evenly distributed around the center
values. The center values should be approximately 2.5.
Specifying axis motion direction
Check or clear the axis Reverse boxes
to specify the direction of motion of
all axes.
