Motion Control With Profibus - Siemens SINAMICS S120 Function Manual

Communication PROFIBUS DP/PROFINET IO
10.2 Communication via PROFIBUS DP
Example: emergency stop with telegram failure
Assumption:
A drive unit with an Active Line Module and a Single Motor Module.
VECTOR mode is activated.
After the ramp-down time has elapsed (p1135), the drive is at a standstill.
Settings:
● A_INF p2044 = 2
● VECTOR p2044 = 0
Sequence:
After a telegram failure (t > t_An), binector output r2043.0 of drive object CU switches to "1".
At the same time, alarm A01920 is output for the A_INF 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.
