4.7.7 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4–20 mA. Common
terminal (terminal X30/8) is the same terminal and
electrical potential for analog common connection.
Resolution on analog output is 12 bit.
6-60 Terminal X30/8 Output
Option: Function:
Select the function of terminal X30/8 as an
analog current output. Depending on the
selection, the output is either a 0–20 mA or
4–20 mA output. The current value can be
read out in the LCP in
parameter 16-65 Analog Output 42 [mA].

6-61 Terminal X30/8 Min. Scale
Range: Function:
0 %* [0 - 200 %] Scales the minimum output of the
selected analog signal on terminal
X30/8. Scale the minimum value as
a percentage of the maximum
signal value. For example, enter the
value 25% if the output should be
0 mA at 25% of the maximum
output value. The value can never
exceed the corresponding setting in
parameter 6-62 Terminal X30/8 Max.
Scale if the value is below 100%.
This parameter is active when VLT

General Purpose I/O MCB 101 is
mounted in the frequency
converter.
