Data Description
8.2 Parameters for SINAMICS S120
p9851 SI STO/SBC/SS1 debounce time (Motor Module)
Setting of the debounce time for the EP terminal of the Motor Module.
The debounce time is rounded- -off to whole milliseconds. It specifies the maxi-
mum duration of a fault pulse at the fail- -safe digital inputs with no associated
reaction on the selection or deselection of the Safety Basic functions.
Example:
Debounce time = 1 ms: Interference pulses of 1 ms are filtered, only pulses
longer than 2 ms are processed.
Debounce time = 3 ms: Interference pulses of 3 ms are filtered, only pulses
longer than 4 ms are processed.
Unit: Default value:
0.00
μs
p9852 SI Safe Stop 1 delay time (Motor Module)
Sets the delay time of the pulse cancellation for the function "Safe Stop 1"
(SS1) on the Motor Module to brake along the OFF3 down ramp (p1135).
So that the drive is able to travel along the OFF3 ramp completely and any
motor holding brake present can be applied, the delay time should be set as
follows:
Motor holding brake parameterized: Delay time >= p1135 + p1228 + p1217
Motor holding brake not parameterized: Delay time >= p1135 + p1228
Also refer to: p1135, p9652
For a crosswise data comparison between p9652 and p9852, a difference of
one safety monitoring clock cycle is tolerated.
The parameterized time is internally rounded- -off to an integer multiple of the
monitoring clock cycle.
Unit: Default value:
ms 0
p9858 SI transition time STOP F to STOP A (Motor Module)
Sets the transition period from STOP F to STOP A on the Motor Module/
Hydraulic Module.
See also: p9658, r9895 and F30611
For a crosswise data comparison between p9658 and p9858, a difference of
one safety monitoring clock cycle is tolerated.
The parameterized time is internally rounded- -off to an integer multiple of the
monitoring clock cycle.
STOP F: Defect in a monitoring channel (error in the CDC)
STOP A: STO as a result of a fault identified by Safety Integrated
Unit: Default value:
0
