Appendix
A.3 Acceptance tests (recommendations)
● Shutdown speed is detected (time axis from approx. 25 ms)
● STOP A (as follow-up response to STOP B) is activated (see bit "pulse enable" = 1); at
this point, the speed falls below the shutdown speed SS1 (p9560) (speed drops below
the shutdown speed SS1 before SS1 timer p9556 has expired)
Not e
Time differences through internal c alculations
Small time differences (of the order of two to three Safety cycles (here up to 7 ms)) are
caused by internal calculations and do not present a problem.
Acceptance test for Safe Direction without encoder with monitoring when the pulses are c anceled
(Extended Functions)
N o .
N o te:
The acceptance test must be individually performed for each configured control and for both directions of rotation.
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)
•
SDI during pulse cancellation (p9509.8 = 0)
•
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 SDI tolerance.
•
Note that regarding SDI, the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start
•
acceptance test".
Please note:
•
With active safety function (e.g. SLS or SSM with activated hysteresis) and for "SSM active" feedback signal
with a pulse inhibit (p9509.0 = 1), the drive enable must be issued within 5 seconds after STO deselection using
a positive edge at OFF1, otherwise STO becomes active again.
3. Switch-on the drive and select SDI positive or negative
Enter a positive setpoint.
Cancel the drive pulses using OFF1, OFF2 or OFF3.
During pulse suppression, monitoring is switched off and the status signal indicates inactive.
4. Check the following values:
r0899.11 = 1 (pulses enabled)
•
r9722.0 = 1 (STO active)
