The acceptance test must be individually performed for each configured control and every SLS speed limit used.
The control can be realized, for example, via terminals, the TM54F 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)
•
No safety message (r0945, r2122, r2132, r9747)
•
2. Deactivate any speed setpoint limit in the higher-level controller
3. Start Trace (trigger r9722.7 = 1/0 edge)
Trace recording of the following values:
Safe actual velocity (r9714)
•
Parameterized STOP X* active (r9721.13)
•
r9720.3 = 0 (SOS selected)
•
r9722.4 = 0 (SLS selected)
•
4. Select SLS
5. Activate the acceptance test mode using p9370 = p9570 = 00AC (hex)
6. Move the drive beyond the speed limit set in p9331/p9531
7. Initiated by the parameterized stop function, the drive must accelerate down to the
standstill limit
8. Save / print the trace (see following example)
9. Deactivate the acceptance test mode using p9370 = p9570 = 0000 (hex)
* STOP C = default, STOP A to STOP D can be parameterized
