Description of control words and setpoints

Note
This chapter describes the assignment and meaning of the process data in
SINAMICS interface mode (p2038 = 0).
The reference parameter is also specified for the relevant process data. The
process data is generally normalized in accordance with parameters p2000 to
r2004. A temperature of 100
100%. For more information, see Section 7.4.
