12.21 SMS (frequency band) via Input (Switch Mode = 19)
With parameter setting “Switch Mode” = 19, an SSM function is assigned to the output.
The center point of the switching point corresponds to the current frequency during the
transition from inactive to active enable flank and is cached in the device. The function
dissolves regardless of the direction of rotation when leaving a frequency band. An
enable input signal is required for the function, which is assigned by the parameter
"Matrix ". A lock function can be attributed. The lock output can be acknowledged
by a further input. A receipt is only possible for frequencies within the frequency band
or deactivated enable signal.
Relevant Parameters Remark
„Switch Mode “
= 19 (Safe Speed Monitor)
„Matrix “
use only inputs, but no feedback outputs
„MIA-Delay “
= 0 (can also be set according to need)
„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 output configuration (affects the Safety Integrity
Level SIL/PL)
„Delay “
shutter release delay
„Presel. .D“
+/-range from the cached center point
„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
