Not e
Time differences through internal c alculations
Small time differences (of the order of two to three Safety cycles (here up to 7 ms)) are
caused by internal calculations and do not present a problem.
SDI positive/negative without encoder and s top response "STOP B"
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 without encoder (p9506 = 1 or p9506 = 3)
•
For "Motion monitoring without selection (Page 205)":
•
- "Safety without selection" configured (p9601 = 24 hex or 25 hex)
- "Safety without selection" activated (p9512.12 = 1 or p9512.13 = 1)
SDI enabled (p9501.17 = 1)
•
No safety function selected.
•
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 regarding SDI, the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start
•
acceptance test".
Please note:
•
With active safety function (e.g. SLS or SSM with activated 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.
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9713[0], r9720, 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:
r9720.12 (deselection SDI positive) or r9720.13 (deselection SDI negative)
•
r9722.0 (STO active)
•
