Time differences through internal c alculations
Small time differences (of the order of two to three safety cycles (here up to 6 ms)) are
caused by internal calculations and do not present a problem.
SDI positive/negative with encoder and stop response "STOP C"
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 with encoder (p9506 = 0 or p9506 = 2)
•
For "Motion monitoring without selection (Page 205)":
•
- "SDI positive or negative" activated (p9512.12 = 1 or p9512.13 = 1)
SDI enabled (p9501.17 = 1)
•
SDI positive deselected (r9720.12 = 1) and SDI negative deselected (r9720.13 = 1)
•
Note: The parameterized SDI monitoring is already active for motion monitoring with-
out selection.
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 the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start acceptance test".
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9713[0], r9721, r9722
•
Select the time interval and pretrigger so you can recognize when the active SDI
•
tolerance has been exceeded and the subsequent drive responses
For better analysis, display the following bit values:
r9721.13 (STOP C active)
•
r9722.2 (SS2 active, set for STOP C)
•
r9722.3 (SOS active)
•
r9722.7 (internal event; set to 0 when the first safety message occurs)
•
