    1. Hello,
      Your post requires several answer.
      First of all, I can only speak for the single channel (the red one) as I did not test the other.
      Yes, it is CANOpen ready, however, it is not activated by default: you have to sold two jumper on the board of the KYDBL 2430-1E ( I don’t know for the other.)
      There is a software to configure the Jinan Keya devices, but it is not directly available on their web site: you have to ask for it.
      There is an EDS file, but you also have to ask for it.
      It seems that the KYDBL 2430-1E has some issue with high bandwidth CAN operation: at the time being, I’m using it at 125 kbps.
      I’m trying to use ros_canopen, but did not test yet: the doc is a bit light. I’m working on it and will update that post soon.

  2. Hey thanks for the post, so useful!

    Also, I am trying to do the same application with other motors and I was wondering, do you have to configure canopen_master first? what’s the difference between canopen_master, canopen_chain_mode and canopen_motor_node? I have taken a look to the documentation but I still don’t get it. Thanks!!

    Felipe
