Posted 11 Jun 2019 (edited) Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works. However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003. This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille Edited 11 Jun 2019 by papaya Share this post Link to post Share on other sites
Posted 11 Jun 2019 Does the servo-drive de-energize? losses power? How do you home your axis? Share this post Link to post Share on other sites

Thank you for your answer the servo-drive has de-energize by the STO, .. i think This axis go home after fault with the same MAM . Share this post Link to post Share on other sites
Posted 12 Jun 2019 Hi, From here it's really difficult to figure out what's happening, I can only guess that when you have an emergency stop the drive de-energizes and losses its home reference and (maybe) that is why the next movement is to move the chain to its next stop in forward direction. Another possibility that I can think of is that the emergency stop resets a sequence, in this case you have to check your program logic. Share this post Link to post Share on other sites
