A.3 Acceptance tests (recommendations)
Trace evaluation:
● SLS function with SLS level 1 is activated (see bits "SLS active", "active SLS level bit 0"
and "active SLS level bit 1")
● Drive is accelerated beyond the SLS limit (time axis from approx. -400 ms)
● Exceeding the limit is recognized (time axis 0 ms)
● Safety fault is initiated (time axis 0 ms; bit "internal event" is set to 0)
● Fault response STOP C is initiated (see bit "STOP C active" and "SS2 active")
● Drive is decelerated to a standstill (see curve of Drive_1.r9714[0])
● After the SS2 timer has expired, the subsequent SOS function is activated (time axis 500
ms)
● The "SOS active" bit is set and "SLS active" is reset
Not e
Time differences through internal c alculations
Small time differences (of the order of two to three safety cycles (here up to 36 ms)) are
caused by internal calculations and do not present a problem.

N o .
N o te:
The acceptance test must be carried out separately for each configured control and each SLS speed limit used.
Control can be realized without selection via TM54F, onboard terminals (CU310-2) or via PROFIsafe.
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)
•
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.
It may be necessary to take measures in the higher-level controller to be able to exceed the active speed limit.
•
Note that the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start acceptance test".
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9714[0], r9721, r9722
•
Select the time interval and pretrigger so that the exceeding of the active SLS limit
•
and the subsequent drive responses can be recognized
