● If the "Safe Stop 1" of the Basic Functions is not selected within the tolerance time in two
channels, this is detected by the cross-check, and fault F01611 (STOP F) is output. After
the set "SI Safe Stop 1 delay time" (p9652), the pulses are suppressed.
Note
In order that the drive can brake down to a standstill even when selected through one
channel, the time in p9652 must be shorter than the sum of the parameters for the data
cross-check (p9650 and p9658). Otherwise, the drive will coast down after the time
p9650 + p9658 has elapsed.
Further notes for setting the discrepancy time (also see the following diagram "Discrepancy
time") are provided in the "SINAMICS S120/S150 List Manual" for the following message:
● F01611 (Basic Functions)
● C01770 (Extended/Advanced Functions)
