  This mode is useful for continuos incremental position movement. For example a robot rolling indefinitely, or an extruder motor or conveyor belt moving with controlled increments indefinitely.
  In the regular position mode, the `pos_setpoint` would grow to a very large value and would lose precision due to floating point rounding.
