PosLowerLevels Property

Application
Force Motion Restriction Object FMR#

Description
This sets or returns the lower threshold value of position of each axis, movement distance and rotation angle at the same time.

Immediate Execution
No

Usage
FGet Object.PosLowerLevels, rArray()
FSet Object.PosLowerLevels, rValuePosX, rValuePosY, rValuePosZ, rValueDist, rValueRot

• Object
  Object name

Detailed Explanation
PosLowerLevels set or return the lower threshold value of position of each axis, movement distance and rotation angle at the same time.
Be sure that PosLowerLevels < PosUpperLevels.
Since lower threshold values for position of each axis, movement distance and rotation angle are set at one time, it can be done with fewer lines than setting them one axis at a time.
This is used for error checking and task completion conditions.

Usage Example
This example generates an error and stops the robot if position, movement distance and rotation angle is less than the lower threshold value.
