Monitoring: telegram failure

Description
After a telegram failure and a 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 a delay time has elapsed (p2044), fault F01910 is output. Fault F01910 triggers fault
response OFF2 (pulse inhibit) for the supply and fault response 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.

Example: emergency stop with telegram failure
Assumption:
● A drive unit with an Active Line Module and a Single Motor Module.
● VECTOR mode is activated.
● After the ramp-down time has elapsed (p1135), the drive is at a standstill.
Settings:
● CU p2047 = 20 ms
● A_INF p2044 = 2 ms
● VECTOR p2044 = 0 ms
Sequence:
After a telegram failure and the monitoring time has elapsed (p2047), binector output r2043.0
of drive object CU switches to "1". At the same time, alarm A01920 is output for the A_INF
