Joystick Y-axis position status
The position of the joystick in the relative motion of travel from the neutral position. The position value of
0 is always neutral. The output range of the joystick handle at the end of travel is factory set according to
the option specified in the electrical interface options section of the master model code.
The master model code specifies that the full-scale output at the end of each linear zone will be 1000
counts.

Warning
Potential uncommanded machine movement. Per the SAE J1939-71 standard, if the JS6000 joystick
internal diagnostics detect a shaft position measurement error, the joystick output will be set to a value
of 1022 counts regardless of shaft position. Application software should be written to recognize this error
condition to avoid the possibility of unintended machine motion.
Per the SAE J1939-71 standard, if a specific joystick axis is not available, the basic joystick message for the
unavailable axis will indicate an output value of 1023 counts. Application software should be written to
recognize this condition to avoid the possibility of unintended machine motion.
