<axis> PLT <value>
Set Positive Limit establishes a positive-direction boundary for movement. If the axis is asked to
attempt a move beyond this boundary, a Position Limit Escape Code will occur and the move will not commence. Jogging is not subject to software limits
since jogging is used for ongoing motion.
Software limits are always active but can be effectively disabled by being set with large values.
When designing homing routines it is usually necessary to widen the software limits until the coordinate system is established to afford freedom to search for the home sensor. Once
the origin of the coordinate system is found the limits can be re-established.
The Positive Limit command does not generate any escapes
This list of commands sets a positive limit, moves within the limit and then tries to move outside the limit"
