Pos1 of CNV1 does not change during conveyor belt operation (DSQC 377B)

  • Hello ladies and gentlemen,


    I have 2 IRC5 each with a DSQC 377B, an IO board (DSGC 652) and a DeviceNet (sst-dn3-pci-1). There are unsorted parts on the conveyor belt, which are recognized by a camera and then tracked by the 377B unit.

    I connected the encoder according to the plan.


    On the IO-Board and the Queue Tracking Module, MS and NS light up green continuously, so they do not give an error. The LEDs on the DeviceNet are also green (Comm and HL T)

    Do I have to connect the frequency inverter to the robot? (I am currently starting it manually and that is enough for my project)


    However, under Jogging, POS1 of CNV1 does not change when I run the conveyor belt.

    Does anyone have any idea what my error is and how I can fix it?


    When I look at the I/O system of "Qtrack1", "c1DReady" is always changing between on/off (1/0) and "c1NullSpeed" is permanently at 1. Otherwise nothing happens no matter if I have the conveyor belt on or off.


    Thank you very much

    Approved the thread.
  • When the conveyor moves, do you see blinking lights change on the DSQ board? The changing lights mean that the board is reading the changes from the encoder. If not, look at wiring before programming.


    Next, see if the counts are changing in the ICI section of the controller in robotstudio. This changing means the controller is seeing the counts from the board. If not, look to make sure your board is configured correctly.


    Finally, check your counts per meter, if they aren't set up, there will be a 0 in there, which results in a 0mm change in position for every count of the encoder, which could result in the issue you're seeing.

  • Hey, thank you for the answer.


    Unfortunately, no LEDs flash on my board as soon as the encoder moves.


    So I'll probably have another close look, even though I was pretty sure that the wiring was correct.
