Data Description
8.2 Parameters for SINAMICS S120
p9650 SI SGE switchover discrepancy time (Control Unit)
Sets the discrepancy time to change over the safety- -relevant inputs (SGE) on
the Control Unit.
Because of the different runtimes of the two monitoring channels, an SIS
switchover is not effective at the same time. After an SGE switchover, a cross- -
comparison of the dynamic data is not carried out during this discrepancy time.
See also: p9850
For a crosswise data comparison between p9650 and p9850, 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 500
p9651 SI STO/SBC/SS1 debounce time (Control Unit)
Setting the debounce time for the fail- -safe digital inputs to control STO/SBC/
SS1.
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:
ms 0.00
p9652 SI Safe Stop 1 delay time (Control Unit)
Sets the delay time for STO for the function "Safe Stop 1" (SS1) on the Control
Unit to brake along the OFF3 down ramp (p1135).
So that the drive is able to travel along the OFF3 ramp completely before
transition into STO, the delay time should be set as follows:
Delay time >= p1135 + p1228
See also: p1135, p9852
For a crosswise data comparison between p9652 and p9852, a difference of
one safety monitoring clock cycle is tolerated.
The set time is internally rounded off to an integer multiple of the monitoring
clock cycle (r9780/r9880).
Unit: Default value:
s 0.00
