ID Known Issue
Graphical User Interface
188126

Return
Cursor disappears when interacting with the position and velocity plots.

Workaround: None.

Reported Version: 2.5    Resolved Version: N/A    Added: 12/15/2009
237934

Return
NI Motion Assistant can crash if you press buttons too quickly.
Pressing any button or combination of buttons faster than about 5 clicks per second can cause NI Motion Assistant to crash.

Workaround: None.

Reported Version: 2.5    Resolved Version: N/A    Added: 09/05/2012
PVT
201636

Return
NI Motion Assistant PVT interpolations cause increasing acceleration oscillations with increased profile length.
In applications where velocity is not held constant, as NI Motion Assistant performs a contour move using a PVT file, over an extended contour the acceleration term begins to oscillate. The oscillation increases the longer the move profile is.

Workaround: None.

Reported Version: 2.5    Resolved Version: N/A    Added: 08/02/2010
Script Execution
134221

Return
Running a script for multiple days may cause NI Motion Assistant to crash.

Workaround: None.

Reported Version: 2.4    Resolved Version: N/A    Added: 12/15/2009
206181

Return
Returning the move to the origin in NI Motion Assistant can cause improper behavior.
When using NI Motion Assistant to perform a series of blended straight-line moves to create a square, returning to the origin coordinate of (0,0) can cause an improper dip in velocity on the the last straight-line move.

Workaround: If the final move returns to 1,1 rather than 0,0 the moves will blend properly. Alternatively, the square can be created moving in a counterclockwise direction.

Reported Version: 2.7    Resolved Version: N/A    Added: 08/02/2010
