Control trinamic servo drive using ros_canopen, error: Could not set transition
Hi, I am trying to use the following tutorial (http://wiki.ros.org/ros_canopen/Tutor...) to run a motor(QMot QBL4208 family - BLDC) using Trinamic TMCM-1636 servo drive(link: https://www.trinamic.com/products/mod...). To keep things simple I didnt change the name of the package and left it as "epos4_canopen" and left the name "maxon" as it was. I am not using a maxon motor drive.
my rosdistro is: noetic, rosversion: 1.15.15
My files, including the candump and dcf files, are located here: https://github.com/nigel-bruce-khan/r...
I used the following guide to edit the eds file: https://www.trinamic.com/fileadmin/as....
From the tutorial at the top, when I run the following line, rosservice call /maxon/driver/init I get the error below:
success: False
message: "/home/nigel/catkin_ws/src/ros_canopen-noetic/canopen_master/include/canopen_master/objdict.h(496):\
\ Throw in function canopen::ObjectStorage::Entry<T> canopen::ObjectStorage::entry(const\
\ canopen::ObjectDict::Key&) [with T = short int]\nDynamic exception type: boost::wrapexcept<std::bad_cast>\n\
std::exception::what: std::bad_cast\n[canopen::tag_objectdict_key*] = 6071\n; Could\
\ not set transition"
And on the terminal with roslaunch epos4_canopen maxon_epos4.launch running, I see the error below when I run the rosservice call /maxon/driver/init command, seen above already:

I have tried not mapping object 6071( Target torque ) in RxPDO 4. That results in the error below:
success: False

I tried changing the data type as suggested here (https://answers.ros.org/question/4063...) that resulted in the same error as the first one above. I could not find CANeds or something equivalent to check my ...
