roboteq_motor_controller_driver_node dies when pubishing /cmd_vel topic

[ghost]

Hi all,

I am trying to control my Motor using Roboteq controller via RS485 communication.

Communication handshake is successful and checked via sending "?FID_" query to the Roboteq controller.

I ran the following commands ,

$ roslaunch roboteq_motor_controller_driver driver.launch

$ rosrun teleop_twist_keyboard teleop_twist_keyboard.py

By running this my roboteq_motor_controller_driver node is shutting down when I am trying to publish the /cmd_vel topic.

Also tried to publish the /cmd_vel topic by different methods.

Anyone faced this issue , if so help me to solve this.

Thanks in Advance.
