Schematic diagram: Applications and results:

Point 1 Point 2
Example 8
Focusing 1 cycle of 2 sequence points:
Two sequences run consecutively. The first
generates a sine wave with increasing ampli -
tude, the second with a decreasing amplitude.
Together they produce a progression as shown
left. In order to ensure that the maximum wave
in the middle occurs only once, the first se -
quence must end with a positive half wave and
the second start with a negative half wave as
shown in the diagram..

Example 9
Focusing 1 cycle of 4 sequence points:
Point 1: 1/4th sine wave (angle = 270°)
Point 2: Three sine waves (ratio of frequency to
sequence point time: 1:3)
Point 3: Horizontal ramp (f = 0)
Point 4: Falling ramp (f = 0)
3.10.10.1 Loading and saving the arbitrary function
The 99 sequence points of the arbitrary function, which can be manually configured with the control panel of the
device and which are applicable either to voltage (U) or current (I), can be saved to or loaded from a common
USB stick via the front side USB port. Generally, all 99 sequence points are saved or loaded using a text file of
type CSV (semicolon separator), which represents a table of values.
In order to load a sequence table for the arbitrary generator, following requirements have to be met:
• The table must contain 99 row (100 are also accepted for compatibility to previous firmwares), with 8 subsequent
values in 8 columns and must not have gaps
• The column separator (semicolon, comma) must be as selected by MENU parameter “USB file separator format”;
it also defines the decimal separator (dot, comma)
•
The files must be stored inside a folder called HMI_FILES which has to be in the root of the USB stick
•
The file name must always start with WAVE_U or WAVE_I (not case-sensitive)
• All values in every row and column have to be within the specified range (see below)
• The columns in the table have to be in a defined order which must not be changed
Following value ranges are given for use in the table, related to the manual configuration of the arbitrary generator
(column headers like in Excel):
Column Connected to HMI parameter Range
A AC start See table in “3.10.10. Arbitrary function“
B AC end See table in
“3.10.10. Arbitrary function“
C Start frequency 0...10000 Hz
D End frequency 0...10000 Hz
E Angle 0...359°
F DC start See table in “3.10.10. Arbitrary function“
G DC end See table in
“3.10.10. Arbitrary function“
H Time 100...36.000.000.000 (36 billion μs)
