Example 8
Focusing 1 cycle of 2 sequence points:
Two sequences run consecutively. The first gen -
erates a sine wave with increasing amplitude, 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 sequence 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 se-
quence 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

“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

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)
