� «Parameters»
Click the «Value» field of the corresponding parameter to define a value. Common parameter
types. Enter a numerical value, a variable, or an expression. Look the meaning up in the parameter
table below.
� «Initial Values»
Click the «Value» field of the corresponding parameter to define the initial values. Common
parameter types. Enter a numerical value, a variable, or an expression. The values are set only
once at simulation start. Look the meaning up in the parameter table below.
� «Angular Dimension»
In the list, select radians or degrees for the angular dimension. The dimension is valid for all
angle input quantities in the machine model.
