Data Description
8.2 Parameters for SINAMICS S120
r9774.0...31 CO/BO: SI Status (group STO)
Displays the status for Safety Integrated of the group to which this drive
belongs. 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 05: SS1 selected in group
1 signal: Yes, 0 signal: No
Bit 06: SS1 active 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

If a drive belonging to a group is deactivated using p0105, then the signals in
r9774 can no longer be correctly displayed (countermeasure: Before deacti-
vating, remove this drive from the group).
A group is formed by appropriately grouping the terminals for the function "Safe
torque off" (STO). 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:
- - - -
r9776 SI diagnostics
The parameter is used for diagnostics.
Bit 00: safety parameter changed, POWER ON required
1 signal: Yes, 0 signal: No
Bit 01: safety functions enabled
1 signal: Yes, 0 signal: No
Bit 02: safety component replaced and save necessary
1 signal: Yes, 0 signal: No
Bit 03: safety component replaced and acknowledgment/save required
1 signal: Yes, 0 signal: No
See also: r9793
Note:
For bit 00 = 1:
At least one safety parameter was changed, that only becomes effective after a
POWER ON.
For bit 01 = 1:
Safety functions (basic functions or extended functions) have been enabled
and are effective.
For bit 02 = 1:
A safety- -relevant component was replaced. Must be saved (p0977 = 1 or
p0971 = 1 or "Copy RAM to ROM").
For bit 03 = 1:
a safety- -relevant component was replaced. Acknowledgment (p9702 = 29) and
save (p0977 = 1 or p0971 = 1 or "Copy RAM to ROM") required.
Unit: Default value:
