Monitoring: Telegram failure
Description
Following a telegram failure and after a monitoring time has elapsed (t_An), bit r2043.0 is set
to "1" and alarm A01920 is output. Binector output r2043.0 can be used for an emergency
stop, for example.
Once a delay time (p2044) has elapsed, fault F01910 is output and fault reaction OFF3
(quick stop) is triggered. 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 PROFIBUS.
