Fig.11-27:
Calculation of a Cartesian coordinate and the angle coordinate
The specified calculation from a radius and a Cartesian coordinate is performed
as follows:
1.
Make sure that the coordinate system on which your calculation is based
is activated. For diameter programming check "Turning".
2.
Enter the pole coordinates. As in all entry fields, expressions are allowed.
3.
Enter the radius in the provided field.
4.
Enter the given horizontal and/or vertical Cartesian coordinate. If only the
distance of the point to the pole is known, activate ">>" in order to switch
over to the incremental entry. Enter the distance with sign and always as
radius measure.
5.
Initiate the calculation using the <return key> or by changing the focus.
6.
In this task, there are usually two solutions. By activating the "Another
Solution" pushbutton, switch over to the desired one, if necessary.
The following error causes can be considered:
●
Inadmissible mathematical operations,
●
Syntax errors,
●
The exceedance of a value range and
●
The entry values do not allow for the geometric calculation.
In the bottom left corner of the form, an error message with the corresponding
reference to the error cause appears. In value range and format errors, the
focus is automatically reset into the field of the latest entry.
Using the <Esc> key, you can reject the latest entry or edit the entry field speci‐
fied in the error message.
If the error has occurred in the geometrical calculation, the error can also be
removed by changing another entry field.
An error condition in the geometrical calculation may occur more
often in repeated calculations of identical tasks after the first given
parameter of the next calculation has been recorded. The interim
condition before completion of all new entries can hardly be avoided
and gives no cause for concern.
