Data Description
8.2 Parameters for SINAMICS S120
r9774 CO/BO: SI status (safe standstill group)
Displays the status for Safety Integrated of the group to which this drive be-
longs. This signals are an AND logic operation of the individual status signals of
the drives included in this group
Bit 00: STO selected in the group
1 signal: Yes, 0 signal: No
Bit 01: STO active in the group
1 signal: Yes, 0 signal: No
Bit 02: SS1 active in the group
1 signal: Yes, 0 signal: No
Bit 04: SBC requested in the group
1 signal: Yes, 0 signal: No
Bit 31: Shutdown paths of the group must be tested
1 signal: Yes, 0 signal: No
A group is formed by appropriately grouping the terminals for "safe standstill".
The status of a group of n drives is, for drives 1 to n–1 displayed with a delay of
one monitoring clock cycle; this is a system–related effect.
Unit: Default value:
– –
r9780 SI monitoring clock cycle (Control Unit)
Displays the clock cycle time for the safety functions integrated in the drive on
the Control Unit.
See also: r9880
Unit: Default value:
ms –
r9794[0...19] SI crosswise comparison list (Control Unit)
Displays the number of the data that are being presently compared crosswise
on the Control Unit.
r9794[0] = 1 (monitoring clock cycle)
r9794[1] = 2 (enable safety–related functions)
r9794[2] = 3 (SGE changeover, tolerance time)
r9794[3] = 4 (transition time, STOP F to STOP A)
...
The list of crosswise compared data depends on the particular application.
Unit: Default value:
– –
r9795 SI diagnostics, STOP F (Control Unit)
Displays the number of the cross–checked data which has caused STOP F on
the Control Unit.
Unit: Default value:
– –
