Please note than NI-CAN and CANOpen library are different

If you want to synchronize 2 motors, you can do what is called trajectory planning. Giving 2 trajectories profile to the motors and program both in a single timed loop (same loop).

I’m sorry I am not be able to do that, because that is copyrighted by NI. You can purchase -at my time- for USD$30, which is very cheap

“I can send single input to my motor, but I think this is very difficult”.
Yes, I can send single data with this form: ID+DATA.
I read the maxon documentation and I understand how to command a motor whit SDO communication.
I think I need a PDO communication because I need to synchronize 2 motors, right?

I can’t try your example for now because i’m waiting for the IXXAT adapter. Your example in labview need subVI in user.lib\canopen\canopen.lib\
I’ve installed the NI-CAN but there isn’t.
Can you zip and send me this directory?

I use a TRINAMIC PCI CARD because i’ve not a IXXAT adapter. So the maxon userinterface do not work in CANOPEN modality.

I also wanted to ask how you installed the libraries CANopen. Thanks

Hi, just browse the labview folder and copy to the library folder. I forgot the details please check on the ni website.

Hi student!
I am an Italian student and I have to realize a system to check a robot of two wheels with two Maxon motors and Epos.
Excuse for my bad English!
I am curious of your video and I see your blog with a lot of pleasure!
I am a person in love of the automation as you; in my project, I will try to check the two wheels for a thesis in my university. you have used LabVIEW for this experiment and the Maxon UserInterface for the movement. Do you have some material on the movement of both the two wheels?
I use a TRINAMIC PCI CARD for canbus communication, but this isn’t recognized from the maxon UserInterface. I can send single input to my motor, but I think this is very difficult! Any packet has a ID and a DATA but from manual I can’t reach how to do (initially I must check the channel speed, then the communication type etc…). What do you use to set your LabView program?
Thanks,
Mattia

Hi Mattia, can you explain more regarding your project? What I understood is that, you want to control a two-wheeled robot using Maxon motor and Epos. I guess you have known that there’s an example to control the maxon motor using labview (If I am not forgotten). Why do you need a TRINAMIC PCI CARD? and you said “I can send single input to my motor, but I think this is very difficult”
