Communication
10.2 Communication via PROFIBUS DP
Example: Quick stop at telegram failure
Assumption:
● A drive unit with an Active Line Module and a Single Motor Module.
● VECTOR mode is activated.
● After a ramp-down time (p1135) of two seconds, the drive is at a standstill.
Settings:
● CU p2047 = 20 ms
● A_INF p2044 = 2 s
● VECTOR p2044 = 0 s
Sequence:
1. Following a telegram failure and once the additional monitoring time (p2047) has elapsed,
2. When F01910 is output, an OFF3 is triggered for the drive.
3. After a two-second delay time (p2044), fault F01910 is output on the infeed and triggers
Note
The additional monitoring time 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.

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.
