Appendix
A.3 Acceptance tests (recommendations)
● Fault response STOP A is initiated (time axis 0 ms; see bit "STOP A or B active" and
"STO active")
● Drive coasts (see red curve of r9714[0])
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.
SLS without encoder with stop response "STOP B"
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 without encoder (p9506 = 1 or p9506 = 3)
•
For "Motion monitoring without selection (Page 205)":
•
- "Safety without selection" configured (p9601 = 24 hex or 25 hex)
- "Safety without selection" activated (p9512.4 =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 active speed limit.
•
Note that regarding SDI, the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start
•
acceptance test".
After selecting SLS, the drive must be switched on within 5 seconds.
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9714[0], r9714[1], r9721, r9722
•
Select the time interval and pretrigger so you can recognize when the active SLS limit
•
has been exceeded and the subsequent drive responses
Select SLS with level x
Switch on the drive and specify the setpoint above the SLS limit
Check whether the drive is moving, and after the SLS limit (p9331[x]) has been ex-
•
ceeded that it is braked along the OFF3 ramp before STOP A becomes active
Check whether the following Safety messages are pending:
