I know it has been quite a while since this project was posted, but I believe there's no harm in asking for help :)
Currently, I am working with a controller that uses hardware_interface::EffortJointInterface. The robot works with JOINTIMPEDANCE strategy `device->doJntImpedanceControl(device_->getMsrMsrJntPosition(), newJntStiff, newJntDamp, newJntAddTorque, false);. The calculated command joint torques are set throughjointhandles[i].setCommand(tau_cmd(i)); ` However, if tau_cmd exceeds the range of -1.0 to +1.0, the hardware drives' contactor will shut off and display a warning: 'LR:FRI cmd.addJntTrq not properly initialized' along with an 'FRI Interpolation error'. When tau_cmd is within the specified range, the robot joints can rotate, but sometimes it struggles to overcome friction."
PS: I have carefully gone through the issue https://github.com/CentroEPiaggio/kuka-lwr/issues/67 , and I believe it is some other issue causing my problem.

Any insights or experiences you could share based on your dealings with this robot would be immensely valuable!!
Any help is appreciated!! Many thanks!! Many thanks!! Many thanks!!
