Axis Wizard/Axis Properties - Units
Use this tab to determine the units you will use to define your motion axis.
When the Logix Designer application is online and the controller transitions to hard run, or the servo loop is on (that is, active), then all the attributes on this tab transition to a read-only state. When any attribute transitions to a read-only state, then any pending attribute changes are reverted.
When multiple workstations connect to the same controller using the application and invoke the Axis Wizard or Axis Properties dialog, the firmware allows only the first workstation to make any changes to axis attributes. The second workstation switches to a Read-Only mode, indicated in the title bar, so that you may view the changes from that workstation, but not edit them.
Parameters
Position Units
User-defined engineering units (rather than feedback counts) used for labeling all motion-related values (e.g., position, velocity, etc.) These position units can be different for each axis.
TIP:
You should choose Position Units based on the maximum ease of use in your application. For example, linear axes might use position units of Inches, Meters, or mm whereas rotary axes might use units of Revs or Degrees.
Average Velocity Timebase
Specifies the time (in seconds) to be used for calculating the average velocity of the axis. This value is computed by taking the total distance the axis travels in the amount of time specified, and dividing this value by the timebase.
The average velocity timebase value should be large enough to filter out the small changes in velocity that would result in a "noisy" velocity value, but small enough to track significant changes in axis velocity. A value of 0.25 to 0.50 seconds should work well for most applications.
