hey everyone just for your interest here is a cnc lathe I am retrofitting here in NZ
link to video on youtube <https://www.youtube.com/watch?v=TphcwK45zyc> still got a whole lot of work and need to sort out analog servo drive stuff tomorrow but thought I would send a email anyway also what do people do for E stop circuits with analog systems? I have only used a step direction system before this the servo drive has a "servo on input) that allows power to motor. I think the enable input from 7i77 should trigger this on and off. I want my big estop to also cut power too though so that I am not relying on software as that is not safe. current plan is to just put a relay in the servo enable circuit from 7i77 to servo drive. which gets cut by the Estop switch circuit. seems simple enough would love any ideas though and any things to watch out for. I know about checking encoder direction first and leaving motors on bench at first and all that sort of stuff. I will just take it easy regards Andrew _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
