A.3 Acceptance tests (recommendations)
Acceptance test for Safe Speed Monitor without encoder (Extended Functions)
Table A- 9 "Safe Speed Monitor without encoder" function
N o .
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)
•
Please note:
•
With active safety functions (e.g. SLS or for SSM with configured 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.
No Safety faults, alarms and messages (r0945[0...7], r2122[0...7], r9747[0...7]) at the
•
drive and TM54F (if one is being used); see note "Non-critical alarms" at the begin-
ning of Section "Acceptance tests."
2. Switch off the drive or specify speed setpoint = 0
Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.15 = 0)
•
Record the following values: r0899, r9714[0], r9722
•
Select the time interval and pretrigger so you can recognize when the level exceeds
•
the SSM limit (p9546) and subsequently falls below it again. You must also trace the
behavior when the pulses are canceled (as a result of OFF1, OFF2 or OFF3).
For better analysis, display the following bit values:
r9722.15 (SSM speed under the limit value)
•
r9722.0 (STO active)
•
r0899.11 (pulses enabled)
•
Switch on the drive and specify the setpoint so that the level briefly exceeds the SSM limit and then drops below it
once more. Then shutdown the drive with OFF1, OFF2 or OFF3.
Check whether the drive is turning
•
3. Analyze trace:
If r9714[0] exceeds the SSM limit p9546, r9722.15 = 0 applies
•
If the hysteresis is active, then r9722.15 only becomes 1 again if r9714[0] falls below
•
the SSM limit p9546 minus hysteresis value p9547.
For p9509.0 = 0, for pulse cancellation, the following applies r9722.15 = 1 and
•
r9722.0 = 1.
For p9509.0 = 1, for pulse cancellation, the following applies r9722.15 = 0 and
•
r9722.0 = 0.
4. Save/print the trace and add it to the acceptance report (refer to the example below)
