Large joint limits

Platform: Process Simulate

This sanity check detects joints with unusually large range limits. For revolute joints, limits exceeding 4 complete rotations (1440° or ~25 radians) are flagged. For prismatic joints, limits exceeding 100 meters are flagged. Such large limits often indicate modeling errors or misconfiguration and can cause optimization issues. The user can review and fix the joint limits or proceed with the export.

Dialog shown in Resolver​

Robot: {robotName}Joint: {jointName} Rotation limit range exceeds 4 complete turnsIndex: {index}, Range: {min}, {max} Verify joint limits

What you can do in this dialog​

  • Can you continue export? Yes
  • Buttons in the popup: Continue, Cancel
  • What happens next: Continue proceeds with the export. Cancel stops this export run.
  • Next step: See impact if you continue

Impact if you continue​

Continuing keeps an unrealistically wide joint range in the exported model. Resolver can consider poses or transitions that the real axis cannot execute, which weakens trust in optimized motion until limits match the physical axis.

How to fix it​

  1. Note the robot, joint, index, and min/max range from the dialog.
  2. In Process Simulate, open that joint’s limit definition and correct the range (unit typos, wrong decimal placement, or mistaken multiples of 360° are common causes).
  3. Save the study, pass the sanity check again (Continue), then run export.
