12.22 No Standstill (Switch Mode = 20)
If the parameter „Switch Mode“ is set to 20, the functionality corresponds to the inverted
Switch Mode = 3. The function is always active as in the Switch Mode = 3, but the output
can only be set up statically.
With this function, the relay output is invertedly controlled to the Switch Mode=3, the
relay is closed at standstill and opened for frequencies different to zero. The Standstill
Time defines a delay before standstill is detected.
Relevant Parameters Remark
Switch Mode XXXX = 20
Pulse Time XXXX Only statically = 0
Standstill Time Standstill time in x seconds
Output Mode homogenous or inverse output configuration (affects the Safety
Integrity Level SIL)
Relevant Input function Remark
no no
12.23 Ramp monitoring (Switch Mode = 21)
With parameter setting “Switch Mode” = 21, a ramp monitoring function is assigned to
the output. The requirement for ramp monitoring is that the braking behavior follows a
linear function of frequency and time. During the transition from inactive to active
enable flank, the current frequency is cached in the device and the expected frequency
can be determined by the pre-programmed ramp parameter "Presel.

.F". If the
current frequency deviates so that the precalculated window "Presel. .

" is left,
the output is set. An enable input signal is required for the function, which is assigned by
the parameter "Matrix

". A lock function can be attributed. The lock function can
be acknowledged by a further input. A confirmation is only possible if the enable signal is
disabled.
Relevant Parameters Remark

„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. . “
+/-range from the cached center point
„Presel. .F“
