Acceptance Test For Safe Speed Monitor (Ssm) - Siemens SINAMICS G130 Manual

10.5.2.7

Acceptance test for Safe Speed Monitor (SSM)

Table 10- 20 "Safe Speed Monitor" function
No.
1. Initial state
Drive in "Ready" state (p0010 = 0)
•
Safety Integrated Extended Functions enabled (p9601.2 = 1)
•
Safety functions enabled (p9501.0 = 1)
•
No Safety message (r0945, r2122, r9747); see note "Non-critical alarms" in the
•
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 = 1)
•
Record the following values: r9714[0], r9722
•
Select the time interval and pretrigger so you can recognize when the level
•
exceeds the SSM limit (p9346/9546) and subsequently falls below it again
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 the drive is turning
•
3. Analyze trace:
If r9714[0] (unit [µm/Safety clock cycle] or [m°/Safety clock cycle]) exceeds the
•
SSM limit p9346/9546, r9722.15 = 0 is valid
Once the level is lower than the limit r9722.15 = 1 is valid
•
If hysteresis is active then r9722.15 only becomes 1 once more if r9714[0] falls
•
below the limit p9346/9546 minus the hysteresis value p9347/9547
For better analysis, display the following bit values:
• r9722.15 (SSM speed under the limit value)
4. Save/print the trace and add it to the acceptance report (refer to the example below)
