Fixed. Freq. potentiometer
The Fixed Freq. potentiometer can be used to adjust the frequency reference value between the f-min
(P-02) and f-max (P-01) limits (the setting is infinitely variable). The potentiometer will become active
after the SET button is pressed (< 1 second). The STATUS LED will flash with a frequency of 4 Hz
when this happens.
When used this way, the Fixed Freq. potentiometer will directly overwrite the value in the DE1
variable speed starter's P-20 (FF1 fixed frequency) parameter.
Note:
The drive's speed can be adjusted directly in RUN mode when there is an FF1 enable signal at the
appropriate control terminal (see modes 0, 2, 3, 4, 7, 8 = P-15). If the SET button is pressed again
briefly, the frequency value currently being transferred will be stored in P-20.

Potentiometer I Motor
The I Motor potentiometer can be used to adjust the value of the motor current (P-08) for the motor
protection function (I
2
t) to a value between 10% and 100% of the DE1 variable speed starter's rated
operational current. The set percentage value needs to be activated in STOP mode by pressing the
SET button (and holding it down for 2 seconds) (the STATUS LED will flash three times for 2 seconds
and will then show a continuous green light).
Mode selector switch
The 10-setting Mode selector switch can be used to configure the DE1 variable speed starter's
control terminals.
The Mode selector switch can only be used if P-12 = 0.
Acronyms and function designations:
FWD = Clockwise rotating field (start command)
REV = Counterclockwise rotating field (start command)
FF1 = Fixed frequency 1 (20 Hz = P-20)
REF = Frequency reference value (0 - +10 V analog input)
EXT FLT = External fault message (if the terminal is open)
FF
0
, FF
1
= Fixed frequencies (binary-coded)
UP = Increase frequency reference value
DOWN = Lower frequency reference value
ENA = Enable signal in combination with DIR
DIR = Operating direction reversal (L = FWD
↔
H = REV)
