Maxon EPOS2 Driver C++ Class using USB-CAN Gateway for Multiple Motor Actuation

I am sharing a C++ Class for multiple Maxon motor actuation by EPOS2 via USB-Can gateway.

The source code is written for two motors, but it is possible to modify easily to actuate multiple motors.

<Download>

If you want to see a simpler version for one motor actuation, see this article. 

I hope this article makes your life easier.

    Hi, Thanks for this very useful work.
    Can you help me about: Maxon EPOS2 driver (MATLAB class) using USB-CAN for two maxon motor.
    i’m very happy if you have some code and send me,
    Best wishes

      HI, Kamil. Have you tried to use the attached file? It includes a class for Maxon EPOS2 and a demo program. If you have a problem to use this, please let me know.

    Hi Youngmok,
    I tried to test this code but I didn’t succeed. I’m very new at GNU licensed code.
    I know that bother you, but I’ll be very happy if you help me.
    I’m working on the system as follows: 2*maxon EC motors and 2*EPOS2 50/5 (AGV). I want to control this system with MATLAB.

    ->node1 connected to the computer via USB and node2 connected to node1 via CANopen. I tried this connection via Epos studio and i run both nodes. now I want to run in the MATLAB (real-time) or I can try with visual c++ 2010 express. (I haven’t tried yet the RS232 interface)

    if you send this code (you share it here) to me as Matlab code or as visual c++ project, I would be very pleased.

    Best wishes

    Kamil,

      Sorry I do not have visual studio, and MATLAB is completely different…. As long as I know, you may download some example files for those platform from Maxon website.

    Hi ,

    Can you please describe the setup for this code to work?

    Does the computer link to one EPOS controller via USB ?

    Do you then you have a secondary EPOS controller connected to the first EPOS controller via the CAN interface connector ? J7 or J8 ?

    I am using the EPOS2 70/10

    Do we need to put these controllers in a specific mode/settings to get this code working ?

    Cheers

    I also find this confusing

    PortName_MCP = “USB0″;
    PortName_PIP = “USB1″;

    nodeId_MCP = 1;
    nodeId_PIP = 1;

    ErrorCode = 0x00;

    Does that mean that the Computer is connected to both EPOS2 controller via 2 separate USB cables ?

    what does MCP and PIP stand for ? why do they have the same value?

    I managed get the simpler version of the code you posted (for one motor actuation) working without any issues.

    Any help would be much appreciated

    Cheers
