canopen_motor_node not sending position commands

edit

Hy there,

I already adressed my issue in this question but the track of the question was lost.

I successfully setup a canopen communication with a igus-dryve motorcontroller with the ros_canopen package. Calling the service /driver/init results in having the joint_state_controller and the position_controller loaded by the controller manager (both running by checking list_controllers service). The motorcontroller-axis does 2 klick-sounds.

Following the terminal output:

 INFO] [1563888510.915229736]: Initializing XXX
[ INFO] [1563888510.915637125]: Current state: 1 device error: system:0 internal_error: 0 (OK)
[ INFO] [1563888510.915873954]: Current state: 2 device error: system:0 internal_error: 0 (OK)
Loaded joint_state_controller
Loaded lifter_joint_position_controller
Started ['joint_state_controller'] successfully
Started ['lifter_joint_position_controller'] successfully
[lifter_ros/controller-4] process has finished cleanly

the communication between the USBCanmodule1 and the igus-dryve keeps alive, this has been proofed by checking the candump can0:

  can0  602   [8]  40 61 60 00 00 00 00 00
  can0  582   [8]  4F 61 60 00 01 00 00 00
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  080   [0] 
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  77F   [1]  05
  can0  602   [8]  40 61 60 00 00 00 00 00
  can0  582   [8]  4F 61 60 00 01 00 00 00

When I now publish a positioning command rostopic pub /lifter_ros/lifter_joint_position_controller/command std_msgs/Float64 "data: 1.0" no changes on the candump appear, so i suppose that the command piped over the joint_position_controller does not get forwarded by the canopen_motor_node.

Calling /halt, /shutdown and /recover works as well fine. I checked my EDS file with CANeds and got 1 warning: (I don't think this could be the problem)

warning 1000: Object [6098]: Default value differs from selected database  (have to be in the range of according data type).

Does anybody have an idea how I could debug this issue or how I could check where problem is in my configuration?

Thank you so much!

Ps. I would also like to turn this example into a tutorial
