    Hello,

    I've got a problem with a Motion control sequence.

    In my code i would like to perform operation like:

    When package move on optice sensor position it stopping and perform MC_Move operation. It's moving for X lenght, but sometimes it stop a little bit after sensor and i would like to stop MC_Move instruction faster - directly when state on sensor goes down. Which instruction use and how to code it to make it good. I already made something like.

    **pseudocode**

    seq=1: if sensor then

               MC_MOVE_instruction_execute=True;

               seq=2

    seq=2:

               f_trig(sensor)

               If MC_MOVE_instruction_done or MC_STOP_instruction_done then

               MC_MOVE_instruction_execute=False;

               seq=3

    seq3:

            REST OF THE CODE

     

    SR_INSTRUCTION(S=F_TRIG.q, R=MC_STOP_instruction_done OR SEQ=3)

    MC_STOP_INSTRUCTION_EXECUTE=SR_INSTRUCTION.Q

     

    Am i doing it right or there is another way?

    Thanks in advance.

    Hello everyone,

    I have a problem with packing machine. There are some issues with one of the axis, when axis actual position is near to 1800000 some error appear and operator has to turn off machine on main contactor. This axis is working in Linear mode. I think that rotary mode would be better for this axis. And here is my question. Which instructions, and what options i should change/check when i change count mode in axis's options. Can any1 point me some manuals to read or give me some advice ?

    Thank you in advance.
