Acceptance test for Safe Stop 1 without encoder (Extended Functions)
N o .
N o te:
The acceptance test must be individually performed for each configured control.
The 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 without encoder (p9506 = 1 or p9506 = 3)
•
Only for "Safe Stop 1 with external stop (Page 90)":
•
p9507.3 = 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 "Acceptance
test."
2. Run the drive
Check whether the correct drive is operational
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9720.1 = 0)
•
Record the following values: r9714[0], r9714[1], r9720, r9722
•
Select the time interval and pretrigger so you can recognize the selection of SS1 and the
•
transition into the subsequent STO state
Select SS1 while the drive is moving
Drive brakes along the OFF3 ramp (not in the case of SS1 with external stop)
•
Subsequent state STO is activated
•
For better analysis, display the following bit values:
r9720.1 (deactivation SS1)
•
r9722.0 (STO active)
•
r9722.1 (SS1 active)
•
4. Analyze trace:
STO is triggered if the speed drops below the shutdown speed (p9560) The configuration
•
of SBR (r9714 [1]) should have approximately the same gradient as the OFF3 ramp. The
curves r9714[0] and r9714[1] should approximately run in parallel.
For p9506 = 3, STO is triggered after the threshold has been fallen below or after the SS1
•
timer has expired.
For p9507.3 = 1, the drive does not brake along the OFF3 ramp. Here, STO is triggered
•
after the SS1 timer has elapsed.
