Acceptance test for Safe Brake Test (Extended Functions)
Not e
Dif ferences to other acceptance tests
SBT is itself a diagnostic function. Unlike the acceptance tests of the safety functions stated
above, in which a violation of the safety function has to be triggered, with SBT it is only
necessary to check the correct parameterization of this diagnostic function.
N o .
N o te:
The test must be performed separately for each configured brake and all the required test scenarios.
1. Initial state
Drive in the "Ready" state (p0010 = 0)
•
Safety Integrated Extended Functions enabled (p9601.2 = 1)
•
Safety functions enabled (p9501.0 = 1)
•
Safety configured with encoder (p9506 = 0 or p9506 = 2)
•
SBT enabled (p10201.0 = 1)
•
All brakes open
•
Enable Safe Brake Control (p9602 = 1) if an internal brake is to be tested.
•
No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]) at the drive and
•
TM54F (if used); see note "Non-critical alarms" at the beginning of Section "Ac-
ceptance test."
2. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r10231.1 = 1)
•
Record the following values: r9713[0], r10231, r10234, r10240, r0080, r0063
•
Select the time interval so that the entire brake test (2 × p10208 + p10211 or
•
2 × p10208 + p10221) of the respective brake can be recorded as of the trigger time.
Set a pretrigger in accordance with the time for selection of the brake test until the
start of the first test sequence (e.g. 1 s).
For better analysis, display the following bit values:
r10231.0 (brake test selection)
•
r10231.1 (brake test start of the test sequence)
•
r10231.2 (brake selection)
•
r10231.5 (external brake status) when testing an external brake
•
r10234.0 (brake test selected)
•
r10234.3 (brake test active)
•
r10234.4 (brake test result)
•
