2 EPOS 24/5 synchronization

Hi all,

 

 I’m using 2 of EPOS2 24/5 Position Controller to control 2 of maxon EC motors (of different 2).  The communication between the host PC and the EPOS are established by serial USB communication. These 2 EPOS controllers communicate between them using CAN bus. I somehow was demanded to make the rotation of these 2 motors synchronous..

Let me put it this way.

I’m using Profile Position mode through which I input position and velocity for the motors to produce a to and fro motion.

Say, I just input them one cycle (say 0, 50, 0 degress for one motor & 0, 75,20,0 degrees for another motor) and made them to reproduce it until I say STOP.

Over here, for every change in angle, corresoponding velocity have to be given.

The problem that I’m facing is that I don’t know how to do the synchronization between the hip and knee motors to ensure that beginning of each consecutive cycle for the hip and knee start at the same time.

Is there any way to overcome this issue other than hardware triggering? 

 

Thanx in advance

I just ran into the same problem with my EPOS2, I want to synchronize two motors by means of the CANBus and control them from LabView by using the USB-bus.

 

Would you care to share your solution?

 

Thanks in advance!
