Motion Control With Profibus - Siemens SINAMICS S120 Function Manual

● CU p2047 = 20 ms
● A_INF p2044 = 2 ms
● VECTOR p2044 = 0 ms
Sequence:
Following a telegram failure and once the additional monitoring time (p2047) has elapsed,
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 two-second
delay time (p2044), fault F01910 is output on the infeed and triggers OFF2.
Note
The additional monitoring time parameter p2047 is only useful for cyclic communication.
During isochronous communication, a telegram failure should be recorded without delay, in
order to respond as quickly as possible.
