I would first check to make sure that your pneumatics are working correctly. I have found on machines I worked on that the silencer, on the exhaust port was partially plugged up, and caused the cylinder to release slowly. A new silencer corrected the issue.
But I do like the suggestions from the others on using direct feedback to notify the controller that the cylinder is in the released position before motion can start. --J.
