SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
Description and comments
Sets the tolerance time for the SGE changeover
Tolerance time for the SGE changeover on the Control Unit
Tolerance time for the SGE changeover on the Motor Module
S
The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 0 95 is set).
S
Due to the different runtimes in the two monitoring channels, an SGE
changeover (e.g. selection/deselection of SH) does not take immediate
effect. After an SGE switchover, dynamic data is not subject to a crosswise
data comparison during this tolerance time.
S
Both parameters are contained in the crosswise data comparison and must,
therefore, be "identical".
Sets the transition time from STOP F to STOP A
Transition time from STOP F to STOP A on the Control Unit
Transition time from STOP F to STOP A on the Motor Module
S
The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 0 95 is set).
S
STOP F is the stop response initiated by fault F01611 or F30611 (SI defect
in a monitoring channel) when the crosswise data comparison is violated.
STOP F normally initiates "no stop response".
S
Once the parameterized time has elapsed, STOP A (immediate safety
pulse cancellation) is initiated by fault F01600 or F30600 (SI STOP A initi-
ated).
The default setting for p9658 and p9858 is 0, i.e. STOP F immediately re-
sults in STOP A.
S
Practical use for STOP F:
Re-configure the stop response for fault F01611 e.g. from NONE to OFF1
or OFF3, for example, (p2100, p2101) and set a sufficient transition time
(e.g. p9658 = p9858 = 500 ms). In this way, STOP F can be used to initiate
stopping via the ramp-function generator (OFF1) or a fast stop (OFF3) be-
fore STOP A cancels the pulses.
S
Both parameters are contained in the crosswise data comparison and must,
therefore, be "identical".
Sets the time to carry-out the forced checking procedure and testing the
safety shutdown paths
S
After this time has expired, using alarm A01699 (SI CU: Shutdown paths
must be tested), is requested to test the shutdown paths (i.e. select/de-se-
lect SH).
S
The commissioning engineer can change the time required for carrying out
the forced checking procedure and testing the safety shutdownl paths.
