4.3.2 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 °C = 100% and an electrical angle of 90° also =
100%. For more information, see Section 7.4.
