• 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
To enable the drive to brake to 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 p965
0 + p9658
has elapsed.
Further notes for setting the discrepancy time are contained in the List Manual for the
following messages
• F01611 (Basic Functions)
• C01770 (Extended/Advanced Functions)
