16.6 Position Error Recovery Procedure
A position error occurs when the difference between the commanded position and the
current position is more than the maximum allowable error limit for an axis.
You can get an error limit if the dispense/spray head hits a hard stop in Manual mode, if
the speed or acceleration is set too high, or if the axes drives are not powered. Make
sure the “Emergency Stop” button is not engaged. The motor stop codes are shown in
the system messages window.
NOTE: Refer to Section 16.8 for more information on stop codes.

necessary.
4. Close the access door.
