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 corresponds to 100% and 0°C corresponds to 0%
• An electrical angle of 90° also corresponds to 100 % and 0° corresponds to 0%
