Limitation in ramp-function generator, ramp-function generator tracking
H369 = 0: The limitation in the ramp-function generator is ineffective. The limitation of the output signal (K100),
but not of the internal integrator in the ramp generator (K096), is effected by means of the
downstream limiter stage (H390...H394).
H369 = 1: The limitation in the ramp-function generator is effective. When the limitations defined via
H385...H387 (L+, L-) are reached, the ramp-function generator (K096) follows the limitation via the
effective ramp-generator setting.
Limitation at ramp-function generator output
This limiter stage can be used completely independently of the ramp-function generator because the input signal
can be freely selected. A special feature of this limitation function is that the lower limitation can also be set to
positive values and the upper limitation to negative values (see H391 and H393). A limit set in this way is then
applied as the lower limit (minimum value) for the output signal of the ramp-function generator in the opposite
sign direction. Please observe the warning given in Chapter 3.11!
Example: H392.01-04 = 2 (= 200%)
H391 = 100.00 (%)
H393 = 10.00 (%)
H394.01-04 = 2 (= -200%)
results in a limitation of the value range of K100 to +10.00% to +100.00%
Velocity signal dy/dt (K095)
This signal specifies the variation in the ramp-function generator output K096 during the period set in H367.
Restriction in SW version 1.0:
In SW version 1.0, the signal dy/dt is generated correctly only if the comfort ramp-function generator is active. If
the change at the RFG output is generated, for example, by a ramp at the RFG input with a lower rate of rise
than the run-up/run-down ramp, then the dy/dt signal is "0" because the RFG ramp time has always expired in
this case. The same also applies when a ramp-up/ramp-down time of "0" is set.

Modes of operation
It is possible to switch over between operating modes either by a parameter setting (H400) or by means of a
control binector (selected via H408).
Automatic mode / Ramp-function generator mode:
The ramp-function generator follows the automatic-mode setpoint. The Raise/Lower commands are ignored.
Manual mode / Motorized potentiometer mode:
The ramp-function generator is operated according to Raise/Lower commands. The automatic-mode setpoint is
ignored.
The following settings can be made in manual mode / motorized potentiometer mode:
Operating range 0% to ±100%, Clockwise / Counter-clockwise:
When "Raise setpoint" is selected, a setpoint of +100% is applied to the ramp-generator input (for Clockwise
selection) or a setpoint of -100% (for Counter-clockwise selection). When "Lower setpoint" is selected, setpoint 0
is applied to the generator input.
