12.19 SOS/SLI/SS2 via Input
(Switch Mode = 17)
With parameter setting “Switch Mode” = 17, an SOS/SLI/SS2 function is assigned to the
output. This function will be triggered by overspeed or by position error, with no regard
of the direction of rotation. An enable input signal is required, which can be assigned by
the Matrix „Matrix
“ parameter. A clear lock function can be attributed The lock
function can be acknowledged by a further input. Acknowledgement is only possible
with frequencies lower than overspeed, or with the enable signal deactivated. With the
switchover the enable signal from inactive to active, the current position is adopted for
error evaluation or cached. SLI and SOS are different with regard to the level of the
switching points only. While SLI corresponds to a monitored Jog operation, SOS provides
standstill monitoring. A position error can be acknowledged only by disabling the Enable
signal. Any SOS function with MIA Delay unequal to zero will turn to an SS2 function.
Relevant Parameters Remark
„Switch Mode “
= 17 (Safe Operating Stop)
„Matrix “
use only inputs, but no feedback outputs
„MIA-Delay “
= 0 (can also be set according to need, SS2 )
„MAI-Delay “
= 0 (can also be set according to need)
„Lock Output“ for lock function use only range 0-31
„Output Mode““ homogenous or inverse (affects the Safety Integrity Level SIL/PL)
„Delay “
shutter release delay
„Presel. .D“
switch point for cached position
„Presel. . “
switching point for overspeed
„Input Mode “
configuration of the control inputs (affects the safety level SIL/PL)
„ IN Function“
function of the control input
„ IN Config“
switching behaviour (single-channel, two-channel, inverse,
homogeneous, dynamic, static)
„GPI Err Time“ max. permissible delay time during illegal conditions
Relevant input functions Remark
Enable, e.g. Parameter „IN1 Function“ = 21 activates the function
Clear lock function, e.g. parameter „IN2 Function“ = 1 … 6 Only when lock function is active
