Monitoring, telegram failure
When monitoring telegram failure, SINAMICS differentiates between two cases:
● Telegram failure with a bus fault
After a telegram failure, and the additional monitoring time has elapsed (p2047), bit
r2043.0 is set to "1" and alarm A01920 is output. Binector output r2043.0 can be used for
a quick stop, for example.
Once the delay time p2044 has elapsed, fault F01910 is output. Fault F01910 triggers
fault response OFF3 (quick stop) on the DO DC_CTRL. If no OFF response is to be
triggered, the fault response can be reparameterized accordingly.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIdrive.

● Telegram failure with a CPU stop
After telegram failure, bit r2043.0 is set to "1". Binector output r2043.0 can be used for a
quick stop, for example.
Once the delay time p2044 has elapsed, fault F01910 is output. Fault F01910 triggers
fault response OFF3 (quick stop) on the DO DC_CTRL. If no OFF response is to be
triggered, the fault response can be reparameterized accordingly.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIdrive.
