9.2.3.2 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
are generally normalized in accordance with parameters p2000 to r2004.
The following scalings apply:
A temperature of 100°C = 100% and 0°C = 0%
An electrical angle of 90° = 100 % and 0° = 0%.
