Function mode
= U/I/P
Function uses U/I/P operation mode (only
available at models from 1kW)
= U/I Function uses U/I operation mode (only
available at models upp to 640W)
= U/I/R Function uses U/I/R operation mode (only if the
option „internal resistance“ is unlocked)

6.15.3 Conguringsequences
The menu pageSequence {1..5} leads to 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
conguredhere,aswellasthesequencepoints.
6.15.4 Sequence related parameters
Sequence control +
Function mode : U/I/P
Function mode of the power supply is displayed.
Seq. cycles {1..254,∞} Default: 1
= {1..254}
it will be repeated n times
 =∞   itwillberepeatedinnitely
P seq= {0…P
nom
} Default: P
nom
The maximum power given here is affecting the whole se-
quence.
This only with option „internal resistance“ (unlockable):
R seq= {0Ω...10 * Ri
nom
} Default: R
nom
The maximum internal resistance given here is affecting the
whole sequence.
6.15.5 Dening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…99:99h}
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
set
= 0V and I
set
= 0A
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 80V/50A/250ms
and the sequence is repeated, then the sequence starts with 80V
and 50A, but with the time that was set for sequence point 0, for
instance 500ms. During that 500ms, the set values will approach
linearlytothedenedvaluesofsequencepoint0.
