Using a SpaceBall
Note
The term SpaceBall is used as a generic term for all 3D motion controllers from 3Dconnexion, including the SpaceBall, SpaceMouse and SpaceTraveler.
A SpaceBall can be used as an alternative to the mouse to move around the main navigation view. The behaviour of the SpaceBall corresponds to the currently selected Navigation Mode. If no mode is selected on the Navigation Mode toolbar or if the selected mode is not a valid mode for the SpaceBall, then a default navigation mode will be used. This enables the user to navigate with the SpaceBall whilst performing other operations with the mouse. The default navigation mode can be set in the Global Options dialog.
The speed of navigation is sensitive to the amount of force applied to the SpaceBall. However, the user can also adjust the speed of translation and rotation by applying a factor to each of these in the Global Options dialog. These options are offered in addition to the adjustments that can be made using the Control Panel for the device which is supplied by the SpaceBall manufacturer with the installation.
Go to Tools, Global Options, SpaceBall
The SpaceBall dialog is displayed

Modify the Scale translation value if you want to increase or decrease the speed of translation.
Modify the Scale rotation value if you want to increase or decrease the speed of rotation.
Select the Default navigation mode from the drop down list. This will be used when no valid navigation mode is currently selected.
