5.2 Control signals by way of terminals on the Control Unit and Motor / Power Module
● 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.
Not e
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 p9650 + p9658
has elapsed.
Further notes for setting the discrepancy time are contained in the "SINAMICS S120/S150
List Manual" for the following message:
● F01611 (Basic Functions)
● C01770 (Extended Functions)
