Acceptance test for Safe Speed Monitor with encoder (Extended Functions)
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 with encoder (p9506 = 0 or p9506 = 2)
•
No Safety message (r0945, r2122, r9747) at the drive and TM54F (if used); see note
•
"Non-critical alarms" at the beginning 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: 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.
For better analysis, display the following bit values:
r9722.15 (SSM (speed below the limit value))
•
Switch on the drive and specify the setpoint so that the level briefly exceeds the SSM limit and then drops below it
once more
Check whether the drive is turning
•
3. Analyze trace:
If r9714[0] exceeds the SSM limit p9546, r9722.15 = 0 applies
•
Once the limit has been undershot, r9722.15 = 1 is valid
•
If the hysteresis is active, r9722.15 only becomes 1 again if r9714[0] falls below the
•
SSM limit p9546 minus hysteresis value p9547.
4. Save/print the trace and add it to the acceptance report (refer to the example below)
