The Joint-to-Cartesian reference frame relationship is automatically established by
the Logix controller after the Joint coordinate system parameters, which are the
link lengths, base offsets, and end-effector offsets, are configured and the MCT
instruction is enabled.

The work envelope is the three-dimensional region of space that defines the
reaching boundaries for the robot arm. The work envelope for an articulated
robot is ideally a complete sphere with an inner radius equal to L1- L2 and outer
radius equal to L1+L2. Due to the range of motion limitations on individual
joints, the work envelope may not be a complete sphere.
If the range-of-motion values for the articulated
robot are:
Typically, the work envelope is:
J1 = ± 170
J2 = 0 to 180
J3 = ± 60
L1 = 10
L2 = 12
