12.24 Ramp monitoring (Switch Mode = 22)
With parameter setting “Switch Mode” = 22, 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". In
contrast to switch mode = 21, only one monitoring of the ramp is carried out.
If the current frequency is greater, so that the precalculated window "Presel.
.

" is left, the output is set. If the current frequency is smaller, so that the
calculated window is left, the output is not 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.
