What did you guys do to prevent it from locking? We don't have a clue

EDIT:
I saw someone mentioning that having a jaguar controlling the arm might be doing something. I don't know if this is true, but we are using two jaguars.
We had a jaguar running our lift mechanism on a window motor and it was locking up as you've described, probably once every few up-down translations. Switched to a Victor and no further problems.
