The NXT firmware does not support a single operation which has the motor run to
a specific tachometer limit and then brake. The only way to do what you would
like to do involves several operations. But you can wrap it all up into a
reusable block (aka subroutine).
Just yesterday I uploaded a new program to the NBC Samples page which includes a
subroutine which does what you want. See the Motors.zip on the Samples page.
In the zip is a program called rot_test.nbc. It has a sample subroutine and
parameterized macro which encapsulates the subroutine call.
