Description
Setpoint branching (output = K9234)
The input quantity is weighted with 2 parameters:
Parameter U297 determines the output value with an input = 0%
Parameter U298 determines the output value with an input = +100%
-U297 and -U298 apply in the case of negative input values.
The hysteresis set in parameter U299 is applied for transitions from negative to positive input values and vice versa

11.65 Simple ramp-function generator
Only active with optional technology software S00
Please note: The output (y) = 0 is set in response to "Set simple ramp-function generator to zero" and POWER ON
The output (y) is frozen at the current value in response to "Stop simple ramp-function generator"
The ramp-up and ramp-down times are set to zero in response to "Bypass simple ramp-function generator"
Ramp-up integrator:
The simple ramp-function generator contains a flip-flop whose output is set to log. "0" (ramp generator initial run) after POWER
ON or when the ramp-function generator has been enabled. When the ramp-function generator output reaches a value
corresponding to the input quantity (y=x) for the first time, the flip-flop output switches to log. "1" and remains in this state until
the next enabling command. This output is linked to binector B9191. By parameterizing U301, index i001=919, it is possible to
apply this binector to the "Bypass simple ramp-function generator" function and thus to implement a ramp-up integrator
function.
