| Summary | Sets the active axis. |
Only one axis can be active at a time, therefore each axis has to be set individually. The settings for each axis are stored in non-volatile memory, and will persist after powering down or resetting. To determine the joystick's current active axis issue the return settings command #53 with a command data value of 25.
Valid Command Data values are:
- 1 (Axis 1)
- 2 (Axis 2)
- 3 (Axis 3)
Subsequent changes to any axis settings will apply only to the active axis.
Settings for the active axis can be changed using the commands shown here:
- Set Axis Device Number (Command #26)
- Set Axis Inversion (Command #27)
- Set Axis Velocity Profile (Command #28)
- Set Axis Velocity Scale (Command #29)
| Axis # | Positive Direction | Negative Direction |
|---|---|---|
| Axis 1 | right | left |
| Axis 2 | up | down |
| Axis 3 | clockwise | counter-clockwise |
Example: To set the maximum velocity of axis number 2 follow the steps below:
- Issue the Set Active Axis command #25 with a command data value of 2 to make axis number 2 the active axis.
- Then issue the Set Axis Velocity Scale (Command #29) using the desired maximum velocity as the command data value. All subsequent "Set Axis…" commands will also apply to the axis number 2 until the user sets a different axis to be the active axis.
