无法开启使能。
你好，我这里用ubuntu20.04 和ros noetic ，elfin5机械臂。
按照技术方案进行环境的配置与部署。
机械臂前期是稳定运行过一段时间，也可以正常使能servo on，控制机械臂移动，今天我按顺序运行
$ roslaunch elfin_robot_bringup elfin5_bringup.launch
$ sudo chrt 10 bash
$ roslaunch elfin_robot_bringup elfin_ros_control.launch
$ roslaunch elfin5_moveit_config moveit_planning_execution.launch
$ roslaunch elfin_basic_api elfin_basic_api.launch
**现象：**在我点击servo on时候，机械臂在使能开启的下一刻，马上自动关闭了使能，并出现以下报错。
api窗口报错如下
Failed to start the default controller
以下是txpdo
rosservice call /elfin_ros_control/elfin/get_txpdo "data: true"
success: True

在此之前，机械臂并未有任何硬件方面的变动，并未有改装或加装东西，突然就这样了。
我也单独用示教器控制机械臂，能正常开启使能并控制机械臂移动。
希望能得到您的帮助。
