Example: Quick stop at telegram failure
Settings:
● CU p2047 = 20 ms
● DC_CTRL p2044 = 0 s
Sequence:
1. Following a telegram failure, and once the additional monitoring time (p2047) has
elapsed, binector output r2043.0 of drive object CU switches to "1".
Alarm A01920 and fault F01910 are output at the same time for the DC_CTRL drive
objects.
2. When F01910 is output, an OFF3 is triggered for the drive.
Note
The additional monitoring time p2047 is only useful for cyclic communication.
