+/-10V Set Value Card for SK 500E
2 technical changes might be possible BU 0920 GB
1. General Information
Set Value Card +/-10V for the SK 500E series provides users with the possibility to control
the inverter through analogue bipolar set values (-10VDC ... +10VDC).
2. Assembly
The card is to be mounted separately from the inverter on a DIN rail within a
proper electrical cabinet (the card is IP00).
3. Function and parameter setting
The Set Value Card converts external bipolar signals (-10V...+10V) into
0...10VDC signals. For that, the input signal voltage level is inverted!
To operate properly, the inverter must be programmed for this!
Notice: SK 500E frequency inverters frame size 5 or bigger, can be adjusted via a DIP-
switch for 0-10V or +/-10V set values, therefore it is not necessary to use the +/-
10V Set Value Card.

P400 Function analogue input 1 1
0 ... 82
[ 1 ]
1 = Sollfrequenz, der angegebene Analogbereich (P402/P403) variiert die
Ausgangsfrequenz zwischen der eingestellten Minimal- und Maximalfrequenz
(P104/P105).
P401 Mode analogue input 1 1
0 ... 4
[ 0 ]
1 = 0
– 10V: A set point smaller that the programmed adjustment 0% (P402) does
not lead to undershooting of the programmed minimum frequency (P104). This
allows a change of the rotation direction.
P402 Adjust analogue input 1: 0% 5,0 ... 5,1
-50.00 ...
50.00V
[ 0.00 ]
Might be needed to adjust to  5,1V
P403 Adjust analogue input 1: 100% 0,0 ... 0,2
-50.00 ...
50.00V
[ 10.00 ]
Might be needed to adjust to  0,2V
P505 Absolute minimal frequency 2,0 ... 3,0
0.0 ... 10.0Hz
[ 2.0 ]
To get a wider hysteresis range on 0V, the absolute minimum frequency can be
adjusted here (maximal setting for the Set Value Card is 3,0Hz).
