Acceptance test for Safely Limited Position
Requirements
● To perform the SLP acceptance test, you must activate the acceptance test mode
(p9570).
● Then you must select the SLP acceptance test (p9575 = 172)
● With the aid of the Safety Control Channel (SCC), a higher-level controller can now be
informed of an active SLP acceptance test through bit 14 in S_ZSWB3 so that the
controller can deactivate the software limit switches.
● If EPOS is enabled, the SLP acceptance test is signaled to EPOS via an internal software
interface so that EPOS can deactivate the EPOS monitoring functions.
SLP with stop response "STOP A"
N o .
N o te:
The acceptance test must be individually performed for each configured control and for both limits in each traversing range
used.
Control can be realized 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)
•
SLP enabled (p9501.1 = 1)
•
SLP deselected (r9720.6 = 1)
•
Drive safely referenced (r9721.7 = r9722.23 = 1)
•
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 position limits.
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9708[0], r9713[0], r9721, r9722
•
Select the time interval and pretrigger so you can recognize when the active SLP
•
limits have been exceeded and the subsequent drive responses
For better analysis, display the following bit values:
r9721.12 (STOP A or B active)
•
r9722.0 (STO active; set for STOP A)
•
