Monitoring: Telegram failure
Description
In monitoring for telegram failure, two cases are possible:
● 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 an emergency stop, for example.
After the fault delay time (p2044) has expired, fault F01910 is output.
Fault F01910 triggers fault response OFF2 (pulse inhibit) for the infeed and OFF3
(quick stop) in the drive.
The fault response can be re-parameterized if an OFF response is not to be initiated.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIdrive.
