«Denominator»«Order»
Enter a numerical value (non-negative integer with or without unit suffix) in the text box to
define the denominator order of the z-transfer function. Please note: You cannot define a variable
or expression in this case. Only a number is accepted.
«Denominator»«Coefficient»
Click the «Value» field of the corresponding denominaotr coefficient P[n] to define a value.
Common parameter types. Enter a numerical value, a variable, or an expression.
Defines the initial values for X (Q[n]) and Y (P[n]). Enter a numerical value, a variable, or an
expression in the text box to define the initial values at simulation start.
Transfers G(s) coefficients into G(z). Define the G(s) coefficients A[n] and B[n] and click
. The G(s) functions are transferred into G(z).
G(z)=Z{L-1 [G(s)]} with L-1 [G(s)]=g(t) and t=k*TS; general: z=es*TS � «Sample Time»
Enter 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.
