Description Of Control Words And Setpoints - Siemens SINAMICS S120 Function Manual

Communication PROFIBUS DP/PROFINET IO
10.1 Communications according to PROFIdrive
drive objects and alarm A01920 and fault F01910 are output for VECTOR. When F01910 is
output, an OFF3 is triggered for the drive. After a delay time (p2044) of two seconds has
elapsed, fault F01910 is output on the infeed and triggers OFF2.

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.
The following scalings apply:
A temperature of 100°C = 100% and 0°C = 0%
An electrical angle of 90° = 100 % and 0° = 0%.
