Dialog Settings
«Integral Gain»
Common parameter type. Enter a numerical value, a variable, or an expression in the text box.
«Initial Value»
Defines the value for t=0. Enter a numerical value, a variable, or an expression in the text box
to define the initial value at simulation start.
«Upper Limit»/«Lower Limit»
Define the value for the upper/lower limit of the output signal. Common parameter type. Enter
a numerical value, a variable, or an expression in the text box. The value '0' for upper and
lower limit means there is no limitation.
� � «Reset Integrator»
If the box is checked, you can enter a reset signal, a reset value, and a control value in the
corresponding text box.
«Reset Signal»
Controls the reset behavior of the integration block. There is a difference between =0 (no reset),
from lower 0 to greater 0, and from greater 0 to lower 0. Usually a variable or a logical
expression are chosen. Enter a numerical value, a variable, or an expression in the text box.
� � «Use Pin»
If the box is checked, the reset signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Reset Value»
Defines the value after a reset event. Common parameter type. Enter a numerical value, a
variable, or an expression in the text box.
«Trigger Setting»
Defines the integration after a reset event. Each value 0 means '1' in the table above.
Common parameter type. Enter a numerical value, a variable, or an expression in the text box.
� «Sample Time»
Select «System» for simulator-defined variable sample time. Select «Value» to define a numerical
value, a variable, or an expression in the text box or use the pin to connect a quantity.
Please note: The sample time must be a positive value.
� � «Use Pin»
If the box is checked, the sample time is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Input Signal»
Enter a quantity name used in your model sheet in the text box to define the input signal
(RLOAD.I, STEP.VAL, STATE.ST, VAR) or use the pin to connect a quantity. Please note: You
cannot use conservative nodes from circuits as input signal (N0002, GND).
� � «Use Pin»
If the box is checked, the input signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
