Hi Can you explain what is the difference between auto reverse in endomotor and otr module??

In reply to Syed Mohammed Big difference. Auto reverse will simply reverse the file out of position for several seconds after reaching a given torque. OTR is mere stutter or reverse cutting for only 90degrees before moving forward. OTR is closer to Reciprocation than auto reverse is. OTR is an efficient cutting motion auto reverse is the original way of trying to make rotation somewhat safer. 
Another major difference is when a file reaches auto reverse it's no longer cutting. But you can cut through OTR motion by continuing the press which essentially turns your rotation motion into reciprocation motion. 
Hope this helps. 
Cheers! :)
