A normal state after start-up of the board is an error code of 0x1C (Motor not
enabled, CommWatchDog, PositionLag)
After an error reset the normal state is 0x04 (Motor not enabled).
After enabling the motor the status is 0x00, now the motor is ready to move.
To reach this state, the communication has to provide values in a fast and reliable
way and, when in position control, in the reach of the motor. These restrictions are
taken to prevent unwanted motion due to e.g. a blue screen on the control PC, a
broken communication, or programming bugs.
