2. Telegram failure with a CPU stop
After telegram failure, bit r2043.0 is set to "1". Binector output r2043.0 can be used for an
emergency stop, for example.
Once the delay time (p2044) has elapsed, fault F01910 is output. Fault F01910 triggers
fault response OFF2 (pulse inhibit) for the infeed and OFF3 (emergency stop) for
SERVO/VECTOR. 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.

Figure 9-23 Monitoring telegram failure with a CPU stop
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.
