i try to change the cw/ccw angle limits permanently to set the servo to wheel mode. I have to change the value of both to 0 for this operation type. When i changed the limits in the terminal with the command:

rosrun dynamixel_driver set_servo_config.py --ccw-angle-limit=0 --cw-angle-limit=0

It has no effect even it shows that it has been changed. i use ros fuerte on ubuntu 12.04 / dynamixel mx 28 i also tried to change the py. code with the write-function from the dinamixel_io.py, but i am not sure using it in the right node. Has anyone suggestions?
