Acceptance Test For "Safe Brake Control" (Sbc) - Siemens SINAMICS S120 Function Manual

10.10.4.4

Acceptance test for "Safe Brake Control" (SBC)

No.
Note:
The acceptance test must be individually conducted for each configured control.
The control can be realized via terminals and/or via PROFIsafe.
1. Initial state
Drive in the "Ready" state (p0010 = 0)
•
STO function enabled (onboard terminals / PROFIsafe p9601.0 = 1 and/or p9601.3 = 1)
•
SBC function enabled (p9602 = 1)
•
Brake as in sequence control or brake always released (p1215 = 1 or p1215 = 2)
•
No Safety faults and alarms (r0945[0...7], r2122[0...7]); see note "non-critical alarms" at
•
the beginning of section Acceptance tests".
r9773.4 = 0 (SBC not requested - drive)
•
r9774.4 = 0 (SBC not requested - group); only relevant for grouping
•
r9773.1 = 0 (STO inactive – drive)
•
r9774.1 = 0 (STO inactive – group); only relevant for grouping
•
2. Run drive (if applied, brake is released)
Check whether the correct drive is operational
•
Select STO/SS1 when you issue the traversing command and check the following:
The brake is applied (for SS1 the drive is previously decelerated along the OFF3 ramp)
•
No Safety faults and alarms (r0945[0...7], r2122[0...7])
•
r9773.4 = 1 (SBC not requested – drive)
•
r9774.4 = 1 (SBC not requested – group); only relevant for grouping
•
r9773.1 = 1 (STO inactive – drive)
•
r9774.1 = 1 (STO inactive – group); only relevant for grouping
•
3. Deselect STO and check the following:
No Safety faults and alarms (r0945[0...7], r2122[0...7])
•
r9773.4 = 0 (SBC not requested – drive)
•
r9774.4 = 0 (SBC not requested – group); only relevant for grouping
•
r9773.1 = 0 (STO inactive – drive)
•
r9774.1 = 0 (STO inactive – group); only relevant for grouping
•
4. Acknowledge switch-on inhibit and run the drive. Check whether the correct drive is operational.
