Output signal troubles

    Hello.

    I'm a beginner and have never worked with Kawasaki before, besides, I'm more into programming than electrics... Now I'm working with KR007L, the controller is F60. I ran into a problem - I can't connect the discret outputs from the controller. I am trying to test the controller outputs by connecting an Omron photoelectric sensor. It has only 3 wires - minus, plus and signal. Before that, I managed to power it from the controller and transmit a signal to the input (when I brought my hand to it, I1 on Monitor1 lit up). Connection is: 0 V (Omron) to 26pin(controller ground) and 6 pin (common); 24 V (Omron) to 50 pin (24 V controller); signal from sensor to 7 pin (1 Input). This works correctly. But I failed to power the sensor from 1 output (for example, 0 V to 30 pin, and 24 V to 31 pin) and then turn on the 1OUT. Thus, there is a voltage between pins 26 and 50, but I can't get it from the output:(

    Once again, the task is not to power up the sensor, but to see if there is a 24V output.

    Tell me, where can there be a mistake?!

    I apologize for my English and thank you in advance for your help.

    That statement suggests you have already wired it up and tested it for functionality.

    ie the sensor to provide an input to the controller as per a standard sensor configuration.

    Is what you are saying, instead of supplying the sensor with a permanent 24V and 0V supply from the controller, you are trying to use an output to power up the sensor instead?

    ie If output 1 is on, sensor is powered up and can provide an input just to test if the output is working.

    Hi, thanx!

    Yes, im trying to use an output to power up the sensor, that is correct. The sensor in this case is just a tool to detect 24V (so as not to use a multimeter).

    Ah ok.

    With Kawasaki, the term COM does not necessarily relate to 0V, it is referring to a COMMON Rail, which dependent on whether NPN or PNP (sinking or sourcing of current).

    When using the outputs you have to determine whether you are sinking or sourcing the current to power it.

    If you are trying to 'see 24V appear on the output' with respect to 0V, then you will need to wire it up as PNP configuration (sourcing of current) as per the page below.

    Where the External 0V and 24V connections are, you can couple those to the internal controller 24V and 0V if you are not using an external supply.

    Just make sure the device your going to power does not pull more than 0.1A ( I very much doubt the sensor will be pulling more than that).

    Well.

    I may have misunderstood you, but it didn't work out for me:)

    I connected 31 pin to 0V (26 pin), and connected 30 pin to 24 V (50 pin). Then I connected the sensor to pins 31 and 30 in parallel and the sensor is now always working (obviously, now it is simply connected in parallel to the internal power supply of the controller). This is not what is needed. I just need to figure out how to connect the controller output and get 24 V from it at a certain output at a certain point in time. As you said "If output 1 is on, sensor is powered up", but not all the time.

    V+ supply pin of your device should be wired to pin 31 (output 1).

    0V supply pin of your device should be wired to one of the internal 0V pins on the controller.

    Pin 30 should be wired to one of the internal 24V pins on the controller.

    Then if you go to the signal monitoring page (outputs), you should be able to turn on/off output 1 to toggle the sensor power on/off.

    Assuming output 1 is not set to any dedicated outputs (Aux 0602) and is not damaged, that should work.

    If the output remains on/stays off, the opto isolator for output 1 is more than likely damaged (short circuit or open circuit).

    Thank you very much!!!

    I do not know why, but 31 pin (1 output) just does not work (I do not know if it is bad soldering of the connector or setting up the robot). I connected 33 pin (3 output) and now everything is working as it should. Plus in karma from me to you.

    Since I came across to frames in Kawasaki and strange settings of bases and coordinate systems, this has been my most difficult challenge :smiling_face: Also, the fact that the DIO connector needs to be soldered, but not clamped in the terminal block, also caused a lot of problems.

    Thank you very much again!!!!! :smiling_face_with_sunglasses:

    Check in Aux 0602 to see if output 1 has been set to dedicated, if it is not in there, I suspect output 1 maybe faulty, or as you say bad soldering.

    Good to hear you got it working on another output...... :top:

    The F controller is designed to be used with a centronics connector as described in the external IO Manual (3-9......3-13) and not soldered wires directly to the board connector pins.

    Then you should look at purchasing one of the following breakout devices, this will make interfacing 100% easier.

    RE: Wiring External I/O (F Controller)

    Welcome to the forum................:beerchug:

    Please check with External IO Manual:

    a. Connected the IO in conjunction with the correct configuration you wish to use (NPN/PNP).

    b. IO requires a power source (24V and 0V) to be used (either internal or external).

    c. These need to be wired to the relevant COM connections for the IO components as per the manual.

    d. Inputs require a COM source for each bank of 8 inputs to operate (Using correct NPN/PNP)

    e. Outputs require a COM source for each bank of 4 outputs to…
