6.15.2 The function layout
Setup function +
You can define the operation mode of the power supply and the
repetition rate here.
Function mode
= U/I/P
Function uses U/I/P operation mode (only
available at models from 1 kW)
= U/I
Function uses U/I operation mode (only
available at models upp to 640 W)
= U/I/R
Function uses U/I/R operation mode (only if
the option „internal resistance" is unlocked)
Also see section „7.1 Defining operation parameters")
Funct.cycles
= {1..254}
it is repeated n times
= ∞
it is repeated infinitely

Task:

Seq.: {-,1..5} {-,1..5} {-,1..5} {-,1..5} {-,1..5}
Beneath the particular tasks you can define of which sequences
the function will consist and in which order the sequences are
used. The symbol „-" indicates, that the task is not defined and
thus won't be processed.
6.15.3 Configuring sequences
Sequence {1..5}
The menu page
where the sequences are edited.
Sequence {1..5} +
It leads to the following menu selection:
Sequence {1..5}
(number of the sequence to edit)
Sequence control
Sequence points 0-4
Sequence points 5-9
The repetition rate of the sequence, the maximum power and
the internal resistance (optional, has to be unlocked) can be
configured here, as well as the sequence points.

Function mode of the power supply is displayed.

The maximum power given here is affecting the whole sequence.
This only with option „internal resistance" (unlockable):
R seq= {0Ω...20 * Ri
}
nom
The maximum internal resistance given here is affecting the
whole sequence.
6.15.5 Defining the sequence points
Sequence points 0-4 {5-9} +
A sequence consists of 10 sequence points. A sequence point
consists of three values: the set values for U and I together with
the time ∆t.
∆t = { 0...99:99 h}
U[ V] = { 0... U
}
nom
I[ V] = { 0... I
}
nom
In order to understand how sequences are processed you need
to consider the start condition of every sequence cycle:
Set values at the start of the function
The function always starts with
U
= 0 V and I
= 0 A
set
set
Set values at reentrance into the sequence
If the sequence is repeated, the last processed sequence point
alters the start condition of the next sequence cycle.
Example: Sequence point 9 is set to the values 80 V/50 A/250
ms and the sequence is repeated, then the sequence starts with
80 V and 50 A, but with the time that was set for sequence point
0, for instance 500 ms. During that 500 ms, the set values will
approach linearly to the defined values of sequence point 0.
