I just have built an experimental set-up(see in the attachment) and there is one question for me. How can I ensure, that the motor axis with the exenter don't move too far down. If the exenter would move too far down there would be a collision with my experimental platform made by wooden and maybe pull the motor out of the fitting. After all the motor with the worm gear can generate a force about 456NM. Would you prefer a solution by setting in the software of Ian or the inverter or a mecanical emergency switch positioned to the exenter down? It woud be very nice to share your experiences with me.

Hi Rolf You can use limit switches. I describe how to connect them in the following thread: motionsim.freeforums.net/post/772/threadYou could also connect the "disable" input of the inverters in these switches, but then they would not recover automatically... Hope that helps. Thanks Thanos

Hi Thanos, that's exactly what I ment. Thanks once more for your quick help! Rolf

Hi Thanos, to clarify your limit SW diagramm for me. It means that I have to stop both wires (e.g.1 A+B) with one NC switch or do you mean two separate NC limit switches on the different sites which position the exenter can take (o° until 180°)? Now you can see a part of my experimental set up in the attachment at least. Rolf

You will need two switches one for 0 degrees and one to 180 degrees positions.

To be more clear, use one NC switch on output A (6DOF ext) for 0 degrees position
and another NC switch for output B (6DOF ext board) for 180 degrees position.
The direction of your motor might not match the 0 and 180 degrees limits switches as I describe above, in that case swap them.
Thanks Thanos

Hi Thanos,
thank you for clarification. Do you have a link for recommended NC switches, which are mecanically stable and suitable for our purposes?
