Link Lengths
Link lengths are the rigid mechanical bodies attached at joints.

Base offsets and end-effector offsets do not apply to a SCARA Independent
robot configuration.
Error Conditions
Kinematics error conditions are detected:
• upon activation of a transformation by executing an MCT instruction.
• in some movement conditions.
Errors can occur for certain movement conditions for either the source
or target coordinate system after a transformation has been established.
These types of errors are reported in the MCT instruction error codes.
Singularity and other movement error conditions are also reported in
the MCT error codes.
• computing an invalid position via an MCTP instruction.
For more information about error codes, see the Logix5000 Controllers

Enter the Link Length values.
For the robot shown in SCARA Independent above,
the Link Length values are:
• L1 = 20
• L2 = 40
